Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. Among them, lithium cobalt oxide is currently the cathode material used in most lithium-ion batteries.
The cycle life of a long-life lead-acid battery is about 300 times, the highest is 500 times, while the cycle life of a lithium iron phosphate power battery is more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. Lead-acid batteries of the same quality are “new half a year, half a year old, and half a year for maintenance”, which is 1 to 1.5 years at most, while lithium iron phosphate batteries used under the same conditions will have a theoretical life of 7 to 8 years. Comprehensive consideration, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge high-current 2C. With a dedicated charger, the battery can be fully charged within 40 minutes at 1.5C. The starting current can reach 2C, but lead-acid batteries have no such performance.
Because lithium iron phosphate power batteries have the above-mentioned characteristics, and produce batteries with different capacities, they will soon be widely used. Its main application areas are:
Large electric vehicles: buses, electric vehicles, tourist attractions, hybrid vehicles, etc.;
Light electric vehicles: electric bicycles, golf carts, small flat battery carts, forklifts, cleaning vehicles, electric wheelchairs, etc.;
Power tools: electric drills, electric saws, lawn mowers, etc.;
Remote control cars, boats, airplanes and other toys;
Energy storage equipment for solar and wind power generation;
UPS and emergency lights, warning lights and miner’s lamps (the best safety);
Replace the 3V disposable lithium battery and 9V nickel-cadmium or nickel-metal hydride rechargeable batteries in the camera (the same size);
Small medical equipment and portable equipment, etc.
