Mercury-free button batteries deep cycle of patent litigation cycle

Thursday, December 31st, 2009

With the use of mercury-containing button cell volume and the increasing volume of waste, waste batteries, mercury pollution of the environment have long plagued the human life. China has independently developed by the mercury-free button cell patent, has passed the edge of life and death are in the 8th year.

The patent has been twice the national patent review committee declared invalid. Beijing Municipal Higher People’s Court of Final Appeal ruling overturned two patent review laptop battery  committee’s decision. In September 2009, the Patent Reexamination Committee announced a third of mercury-free button cell patent is invalid, the patent owner of the third patent review committee to resort to the courts. The case is currently pending under the Beijing Municipal No. 1 Intermediate People’s Court.

■ patented technology is no longer a secret at all

Why was there for the mercury-free button batteries have been repeatedly declared the patent invalid, the reporter interviewed a number of contacts of national patent review committee and in accordance with the requirements of the other fax an outline of the interview, but last Friday, the Patent Reexamination entrusted with the inconvenient interview camcorder battery and refused to interview with reporters.

According to reports, in accordance with our rules of patent protection, patent protection is a patented invention, the disclosure of patented technology for the premise that the inventor in patent applications at the same time, to declare its own patented technology secrets made public. That is, if the patent is declared invalid, the inventor is also no longer a secret at all, other manufacturers can not put any development funding for free public use of the technology of others, rather than held accountable under the law does not assume any liability.

■ 10-year patent protection period is about to expire

Mercury-free button on the camera battery patent license notice, after a further round of the battery businesses and individuals began to Patent Reexamination Board to submit a request to declare the patent invalid mercury-free button batteries.

May 31, 2004, the National Committee of the patent reexamination of enterprises according to two batteries apply to mercury-free button batteries do not have the creativity, and declared all of the patent is invalid. The Guangdong companies to court Leader, December 20, 2005, the Beijing Municipal Higher People’s Court of Final Appeal ruling committee loses patent reexamination, the court found that mercury-free button batteries all the valid patent.

June 19, 2009, the State Patent Reexamination Committee make a decision the third time, to mercury-free button batteries do not have the creativity, and declared all of the patent is invalid. In October 2009, Guangdong New Leader’s third patent review committee sue in court, asked the court to revoke the patent review committee’s decision null and void. At present, mercury-free button batteries 10-year patent protection period is about to expire  battery charger, the ultimate fate of the concern of the patent.

■ “judicial finality” Why is it difficult to finality?

An interview with intellectual property experts. Experts in the field, the original court in Beijing, a tribunal of senior judges to know middle Guang-Liang Zhang told reporters before the WTO, the case involves a utility model patent license and maintenance procedures, are “administrative finality”, that National Patent Reexamination Board makes its decision direct the force of law, the parties have no right to bring administrative proceedings.

Keeping with international standards, China’s “Patent Law” was amended accordingly, and change “executive finality” for “judicial finality”, that is made by the administrative department of intellectual property satisfied with the ruling, the parties have the right to bring an administrative lawsuit. The final decision by the court.

Knowledge of lithium iron phosphate battery

Tuesday, December 29th, 2009

Lithium iron phosphate batteries are currently no widely used, but was hailed as the future scientists, a new lithium battery. It has several advantages.

1, long life
Long-life lead-acid battery cycle life of about 300 times the maximum also 500 times, some bias battery for more than 2,000 times, the standard charge (5 hours rate) to use, up to 2000 times. The quality of lead-acid batteries with the most frequently used also a ~ 1.5 years, while the lithium iron phosphate camera battery used under the same conditions, it will reach 7 to 8 years. Taken together, cost performance will be four times more than lead-acid batteries.

2, the use of safety
Lithium iron phosphate lithium cobalt completely resolved and the safety of lithium manganese oxide hidden problems, cobalt and manganese lithium lithium in the strong collision will produce an explosion under the right pose a threat to the safety of consumers, while the lithium iron phosphate to undergo a rigorous safety testing, even in the worst accident will not produce an explosion.

3, can be high current
2C fast charge and discharge, under the dedicated charger, 1.5C within 40 minutes you can recharge the battery is full, the starting current of up to 2C, but now there is no such performance of lead-acid dell battery.

4, high temperature, lithium iron phosphate peak heating up to 350 ℃ -500 ℃ and the lithium manganese oxide and lithium cobalt only about 200 ℃.

5, high-capacity.

6, no memory effect.

7, small size and light weight.

8, green environmental protection.
Lithium iron phosphate battery is truly safe lithium-ion batteries
Lithium iron phosphate battery with lithium iron phosphate (LiFePO4) as cathode material, is true security through the abuse of the test battery. LiFePO4 high temperature does not decompose when exposed to heat, in overcharge or short circuit the battery case of physical and chemical properties of its extremely stable. Battery abused, LiFePO4 and will not be released or thermal runaway due to heat caused by burning the battery. Under the battery 3.6A5V overcharge, the dell Inspiron 1521 battery will not exceed a maximum temperature of 55 ℃, very safe, hot-box test, 7 to 8 hours after heating to 300 ℃ process, the battery temperature is almost in line with the case temperature does not appear in short, squeeze and acupuncture, the temperature does not exceed 110 ℃.

Mining equipment in terms of security requirements is particularly high, which also pairs of lithium batteries have higher requirements. At present, the lithium battery on the market they use lithium cobalt oxide and lithium manganese oxide as cathode material. Lithium iron phosphate battery using lithium iron phosphate as a cathode material, with olivine-type structure to meet the ideal high-security, high-capacity high-power lithium batteries needed LiFePO4, known as “lithium-ion battery of a new era.”
LiFePO4 non-toxic, environment-friendly, rich in raw materials than the high capacity, charge-discharge stable cycle performance, thermal stability, high, very safe and reliable, using the materials of lithium-ion batteries is ideal for safety, cycle life, power characteristics, the use of extremely cost-sensitive battery applications.
Lithium iron phosphate battery, safety miner’s lamp is fully guaranteed, even under conditions of abuse, it will not fire explosion, but life is a traditional lithium-ion battery 2 times.

Currently, in China, Dell notebooks on the market a total of four broad categories: one, family and home office; 2, growth-oriented enterprises; 3, medium-sized enterprises; 4, government, educational and medical institutions.

But for ordinary consumers, the above-mentioned classification does not have a reference value: after all, to get the user in the hands of DELL laptop battery uses are diverse, a flagship business notebook could be used to play games; the main gaming notebook may also be used for office. Well, we still have to return to visible, tangible, real machine.

Dell Notebook Series Home

Dell’s notebook on the current model in terms of a “Inspiron series, XPS series, Vostro achievements Series, Latitude Series, Precision Series” five series, we will focus on issues of public concern in front of the three series.

1, Dell Inspiron Series

Inspiron word is rooted in the word inspire, and inspire has to generate inspiration, revelation was intended. Clearly, Dell, the meanings of words to create such a self-evident. Dell Inspiron needs of the user group is faster performance, the latest technology and premium prices, at the same time does not require long-term product life-cycle management of product transition and the individual users and home users.

Let me know how to make my laptop batteries use more durable?

Thursday, December 24th, 2009

1. Read carefully before using the laptop battery maintenance part of the manual;

2. The first charge, you should continuously charge the battery to 12 hours, and the loop to fully charge and discharge completely 3 times to wake up a new battery;

3. If the prolonged use of an external power supply, preferably remove the dell Inspiron 1501  battery. Many of my friends no attention to this issue, remove the battery without external power supply not only affect the battery life, but also allow notebook computers to become even heavier burden on the heat to shorten the life of notebook computers;

4. Periodically charge and discharge. Even without the memory effect of lithium-ion battery there is a certain inertia effect for a long time not to use lithium-ion loss of activity would need to re-activation. Therefore, if a long time (three weeks or longer) without using a computer or found that the battery charge and discharge time shorter, should be fully discharged and then recharge the battery, generally a month for at least a full charge and discharge 1.

5. Best to switch off the notebook when charging, the dell Inspiron 1520  battery can be fully charged, do not unplug the power in the charge half-way. Charging off recharge shorter than the boot more than 30% of the charging time, but also to extend battery life. The best finish for 30 minutes in the charge before use.

6. To prevent the exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with metal objects touch the battery short-circuit, etc. happen. Lithium battery charging and discharging of the number of generally not more than 800 times, on one charge, it will shorten a life. Suggest that you try to use an external power supply, many times if you use half-way Plug Power, and the laptop does not pull out the built-in battery will give the battery life shortened by large, because each access to external power supply is equivalent to charge the battery once.

Optimization of power management options to set

For notebook computer users, we recommend the use of WindowsXP operating system, of course, if the laptop’s configuration is too low or even WindowsXP can not meet the minimum configuration requirements, it is another matter.

There are many reasons, the main point is that the notebook power management is the most advanced of all computer operating systems, if combined with Centrino platform, the better.

1.6GHz of the Pentium-M load is small below only work in the 600MHz frequency. If your laptop supports Intel SpeedStep, AMD PowerNow  or Transmeta’s LongRun technology, we must remember that the latest drivers installed, to play its biggest utility, WindowsXP is automatic, you can follow their own requirements in terms of performance and power to find a balance.

Users can do the most optimized power management settings, 1. Do not use a screen saver.

2. The power to use the program, select “Portable / Laptop”, the following of the time as you need a reasonable setting, everyone’s circumstances vary, inconvenience to make mandatory. General to shut down the hard drive time setting time was slightly longer than the stand-point, so as not to affect the hard drive life.

3. Enter “Power Options” attribute in the “Advanced” reasonable use “power button”, give you great convenience, can also enhance the rational use of battery life. For example: the phrase “together on a portable computer” is set to “standby”, which left the laptop for a while, the only power but also the confidentiality of private information helps a lot, but not need to wait to restart the time. For the first-line maker of notebook computers (such as IBM, SONY, HP, Toshiba, etc.), often provide some better dell Inspiron 1521 battery power management software, and has some special features: IBM’s power management program can reduce the LCD screen refresh rate; TOSHIBA Toshiba’s power management program in the absence of sufficient direct power off your device in any designated 1; SONY dedicated power management program can set the cooling fan speed, you can also turn off non-use of the IEEE1394 interface and MEMORY STICK slot in order to achieve energy-efficient head to.

Energy Saving Hardware

In the use of laptop computers, we can do the hardware energy have the following main categories: 1. To reduce the brightness of laptop LCD screens, LCD liquid crystal screen is large power consumption in notebook computers, we can reduce the screen brightness to the appropriate to reduce its consumption of electricity, the majority of notebook computers through the “Fn” + “F8″ or “F9″ to adjust the screen brightness, there is usually an optional eight kinds of brightness, the brightness is generally used on almost the middle of the key to your personal hobby .

2. Notebook computers will be taken into account in the design expansion of capacity to facilitate the connection with other devices. So we will see a lot of laptops around the peripheral devices can be connected to an extension of mouth, as long as reasonable layout and of course, is to extend the mouth, the stronger the more scalable. However, each port needs power, too much on the external interface to an unnecessary increase in power consumption and shorten dell Inspiron 1525  battery life. Notebook computers LPT, serial most people rarely used, it is recommended in the BIOS will disable them. If your laptop has infrared capabilities, without having time to also put it off, which in the “Device Manager” can be directly disabled, and when the need arises to open.

3. Now almost all of the computers have built-in Modem and network card, it is best to switch off them when needed and then opened. A lot of computers coupled with a wireless card, if you temporarily do not have access, it is recommended to disable, otherwise it is in constant search of the network, consuming unnecessary electricity.

4. Drive energy savings. Maximize notebook memory to improve performance and reduce power consumption hard drive constantly reading, memory is reached 512MB, using the Windows XP system, you can disable the virtual memory to avoid frequent disk read.

5. Some notebook computers will adjust the BIOS in the CPU and other parts of the state of energy-saving technologies, check the feature is turned on.
In use to save on the usual use as long as we pay attention to the dell Inspiron 1526  battery power consumption can be reduced. Here we summarize it, so that you can pay attention to in use.

1. Peripherals connected to the expansion of the mouth immediately after use to remove, such as printers, scanners, digital cameras, mobile hard drives, USB floppy drive and so on. As long as these peripherals connected to the laptop computer, even if no work will consume battery power;

2. If the PCMCIA slot expansion card is no need to use, should be immediately removed;

3. Laptop computer power drive great no need to use the CD-ROM to be taken out, otherwise it would intermittently read, to increase energy consumption. Smooth performance notebook cooling heat and power relationship between the two are very close, this is the heat from the laptop way to decide. Notebook computers generally use the temperature-controlled fan with heat pipe cooling technology, and only reach a certain temperature will enable the built-in cooling fan. Once the notebook computer’s internal air circulation by heat pipe heat can not be spread out in time, will lead to the fan stop running.

Since only a notebook computer’s internal temperature reaches a certain temperature-controlled fan will run, then we note the following points can reduce the fan power consumption.

1. As far as better ventilation or air-conditioned rooms.
2. Do not let debris and dust blocked cooling holes in notebook computers, heat pipe, heat sinks, the internal parts can not be too dirty, I have been dismantled to a notebook everywhere, a thick gray, that would lead to heat a lot of trouble.
3. In the home or office use, the best preparations for a good cooling effect of water cushion pad at the bottom through the water cushion so that laptop for better cooling.

Lithium-polymer battery with high-end notebooks

Tuesday, December 15th, 2009

With several major international manufacturers cut-off batteries, notebook battery is facing out, resulting in notebook shipments hit a bottleneck. According to the statistics: in 2008 the global notebook shipments reach 130 million units, compared with 101 million units in 2007 growth of about 28%, such a rapid growth of the output gap with the sony VGP-BPS2 battery so much so that Hewlett-Packard, Dell and other international notebook manufacturers have to look to invest in lithium-polymer batteries. However, the cost of lithium-polymer battery is now widely in use than higher than 50% of lithium batteries. These international firms will use lithium polymer batteries for it?

Notebook industry sustained rapid growth, but limited sony VGP-BPS2A battery  module the problem of inadequate supply, mainly due to an imbalance between supply and demand caused by the battery core Queliao. In order to effectively alleviate the battery cell Queliao, the international brand makers intended to increase the adoption of a more high-end, cost more than 50% of the lithium-polymer (Li-Polymer) batteries, the battery module manufacturer in Taiwan, according to the industry pointed out that, in addition to Apple’s long spearheaded the introduction of Lithium-polymer batteries, the current Hewlett-Packard, Dell, also plans to follow up on some of the new high-end models use lithium polymer battery, notebook battery module to supply in 2008 to add new momentum, but also for the second half of the world’s notebook out of Cargo growth inject momentum.

Not only the sony VGP-BPS2B battery,sony VGP-BPS2C batterycell assembly plant in order to consolidate the material sources Queliao everywhere, the international laptop brand notebook makers in order to allow shipments to be smooth, multi-Sourcing. However, the battery cell are subject to the current production capacity is limited, new capacity has not yet out, it is estimated that in 2009 will continue to tight supply and demand, and the gap roughly about 10%, natural or unable to meet the needs of the existing notebooks.

Scientists made the United States “virus cell” used in notebook computers

Monday, December 14th, 2009

Massachusetts Institute of Technology scientists have used the virus creates a environment-friendly high-power lithium-ion battery, the dell Inspiron E1405 battery could be used to power portable electronic devices and hybrid vehicles.

Scientists will be published on the 3rd
The new issue of “Science” magazine published an article, said that they will first strip of the M13 virus, genetic programming, so that it can be grown as the electrode surface of amorphous iron phosphate. Generally speaking, amorphous iron phosphate is not a good conductor, but it is in the nanometer scale has become a useful dell Inspiron E1505 battery materials. The end of these viruses are designed to work with carbon nanotubes to connect, thus creating an increase in the battery inside the conductive properties of network structure.

Scientists have used microscopes to the hundreds of millions of viral DNA scanned, identified the M13 virus. This virus length of 880 nm is a very simple and easy manipulation of the virus, harmless to human body.

The researchers found that with the carbon nanotube, “binding” of genetically modified virus can make iron phosphate electrode charge-discharge rate and the current state of the art of crystalline lithium iron phosphate electrodes comparable. This “virus cells” can charge and discharge at least 100 times without loss of capacitance, although lithium iron phosphate dell Inspiron E1705 battery are still gaps, but the latter is expensive and toxic, while “virus cell” There are clear advantages: You can at room temperature or below room temperature preparation, no harmful organic solvents, are also non-toxic material inside the battery.

Who led the study Anjielabei Pilcher said they next plan to use can produce higher capacitance and voltage of the substances, such as manganese phosphate, phosphoric acid and nickel to develop better performance of the batteries, and look forward to the relevant technologies can be commercialized as soon as possible application stage.

Six Summer Note of the laptop use

Friday, December 11th, 2009

During the hot summer, how can the health and safety through the books is that all netizens concerned about an issue, I am going to talk about the summer, using a dell Inspiron 6400 battery on several considerations.

1. Work and rest. Notebook also need to pay attention to rest a long time use, the notebook’s temperature will rise a lot, so during the break, you can use sleep / sleep / standby, etc., so that laptop can be a very good rest.

2. To keep out the outlet flow. When you use the notebook do not let things that blocked out the draft, paying particular attention not to the soft cushions on the bed or using a DELL laptop battery. In addition, the summer before the arrival of a draft for the notebook’s heat sink, fan and other parts of the cleaning, is also a very good Idea.

3. An appropriate booster books. We can artificially elevate notebook, the notebook at the bottom to bring better air circulation and heat away faster. If the prolonged use of laptop, notebook under arms in copper, steel and some other materials conducive to heat dissipation. Do not booster the same time, be sure to pay attention to maintaining a stable notebook.

4. To maintain ventilation. In the summer, be sure to use the notebook to keep the room ventilation, air circulation in order to ensure a good notebook cooling.

5. Cooling base. Now there are a lot of notebooks on the market dedicated cooling base, you can choose according to their needs, enhance notebook dell Inspiron 1501 battery cooling.

6. As far as possible the use of air-conditioned room. Heat of the summer, conditional of course, where there is air-conditioned environments, not only their own comfort can also be a good solution to notebook cooling environment.

How to divide laptop battery batteries?

Friday, December 4th, 2009

In the market we see some laptop batteries ads, almost all have adopted the A-cell batteries, it is not all of the battery factory only produce A-batteries do? The answer is definitely no! So how do we distinguish between batteries category?

Manufacturers in the production of the same group of cells when the battery discharge test based on the performance of classification, ABCD is divided into four categories (Sanyo distinction, as this way the distinction between Sanyo and Panasonic has actually become the industry standard), A = 2000MAH , B = 2200MAH, C = 2400MAH D = 2600MAH, the battery on the distinction between marked with ABCD code, and then at the same time shielding gas in the sony VGP-BPS8 battery cover to distinguish color (when the battery will discharge gas, the battery positive to have a protective cover, When the battery is deflated to a certain amount of time, that is soon to meet the design life of the time, the gas would be to open the lid to the top, so that the battery off road), this is the source of ABCD, as Sanyo and Panasonic’s strength, this is also On the difference between the industry has become the default mode. Of course, this by the production technology limits are to stop the original 2400mah Sanyo batteries internal material composition in favor of new material formulations, therefore, the current production of 2000-2600mah Sanyo’s batteries, is actually different from the same production line quality products.
