LiFePO4 Rechargeable 3.2V 50Ah Battery Cell for AGV
The LiFePO4 battery refers to a lithium ion battery using LiFePO4 as a positive electrode material. The positive electrode materials of lithium ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, LiFePO4 and the like. Among them, lithium cobaltate is the positive electrode material used in most lithium ion batteries.
The P-O bond in the LiFePO4 crystal is stable and difficult to decompose, and does not collapse or heat like a lithium cobaltate or form a strong oxidizing substance even at a high temperature or overcharge, and thus has good safety.
Lithium iron phosphate is currently used in many alternative lead-acid battery projects, such as golf carts, forklifts, AGV and other lead-acid batteries, which are now being gradually replaced with lithium iron phosphate batteries. Like 3.2V 50Ah LiFePO4 Cell for AGV.
It has been reported that in the actual operation, a small part of the sample was found to have a burning phenomenon in the acupuncture or short-circuit test, but there was no explosion event. In the overcharge experiment, a high-voltage charge that was several times higher than the self-discharge voltage was used, and it was found that there was still Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared to the ordinary liquid electrolyte lithium cobalt oxide battery. The long-life lead-acid battery has a cycle life of about 300 times, and the highest is 500 times. The lithium iron phosphate power battery has a cycle life of more than 2000 times, and the standard charge (5 hour rate) can be used up to 2000 times.
