Knowledge of lithium iron phosphate battery
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.
