What are the advantages of lithium iron phosphate batteries

　　1. Improvement of safety functions

　　The P-O key in lithium iron phosphate crystals is stable and difficult to distinguish. Even if it is high temperature or over-charged, it will not be like lithium cobalt oxides with structure collapse or constitutes a strong oxidation substance, so it has excellent safety Essence Chen pointed out that in actual operation, a small number of samples were burned in acupuncture or short -circuit tests, but no blasting. However, in the overcharge test, a high voltage charging that is several times higher than the discharge voltage itself will still explode. However, compared with ordinary liquid electrolyte lithium cobalt batteries, the overcharge safety of lithium cobalt oxide batteries has made great progress.

　　2. Longevity of improvement

　　Lithium iron phosphate cells refer to lithium ion batteries based on lithium iron phosphate.

　　The circulation life of long -life lead -acid batteries is about 300 times, up to 500 times, and the cycle life of lithium iron phosphate power lithium batteries reaches more than 2000 times. Standard charging (5 hours rate) can reach 2000 times. Lead -acid batteries of the same quality have a new half -year, old half -year, protection for half a year, and protection for half a year. At most 1 to 1.5 years, the theoretical life life will reach 7 to 8 years as the same conditions are under the same conditions as lithium iron phosphate battery. Infuse considerations, the functional price is theoretically more than 4 times that of lead -acid batteries. Large -current discharge can be large -current 2C quickly and quickly charged. Among the special chargers, the battery can be filled within 40 minutes of charging, and the current can reach 2C, while the lead -acid battery does not have this function.

　　3. High temperature function well

　　The electric peak of lithium iron phosphate can reach 350 ° C-500 ° C, while the electric peaks of lithium manganate and cobalt oxide lithium are only about 200 ° C. The scale of working temperature is wide (-20C75C), and lithium iron phosphate with high temperature resistance can reach 350 ° C-500 ° C, while lithium manganate and lithium cobaltate can only be around 200 ° C.

　　4. Large capacity

　　The capacity of the rechargeable battery is less than the additional capacity value of the always full situation. This phenomenon is called the recovery effect. There is a recall of nickel -metal hydride and nickel -cadmium batteries, but there is no such phenomenon of lithium iron phosphate ion batteries. Under what circumstances are the battery, it can be used with charging. Do not take it out before charging.
