What are the advantages and disadvantages of lithium iron phosphate batteries? What are its application areas?

Lithium iron phosphate battery refers to a lithium battery that uses lithium iron phosphate as the positive electrode material. The important cathode materials of lithium batteries include lithium cobalt oxide, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. Among them, lithium cobalt oxide is the cathode material used in most lithium batteries at present. 1. The life of lithium iron phosphate batteries is long, with a cycle life of more than 2000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years. 2. Safe to use. Lithium iron phosphate batteries have undergone strict safety tests and will not explode even in traffic accidents. 3. Fast charging. Using a dedicated charger, the battery can be fully charged after 40 minutes of charging at 1.5C. 4. The lithium iron phosphate battery is resistant to high temperatures, and the hot air value of the lithium iron phosphate battery can reach 350 to 500 degrees Celsius. 5. The lithium iron phosphate battery has a large capacity. 6. The lithium iron phosphate battery has no memory effect. 7. Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, has a wide range of raw materials, and is cheap. Disadvantages of lithium iron phosphate batteries 1. The tap density of the positive electrode of lithium iron phosphate batteries is small, and the density is generally about 0.8 to 1.3. huge size. 2. Poor conductivity, slow diffusion of lithium ions, and low actual specific capacity during high charge and discharge. 3. The low temperature performance of lithium iron phosphate battery is poor. 4. The life of a single battery of lithium iron phosphate battery is long, about 2000 times, but the life of lithium iron phosphate battery pack is short, generally about 500 times. Application areas of lithium iron phosphate batteries: 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, chainsaws, lawn mowers, etc.; remote control cars, boats, airplanes and other toys; solar energy and wind power storage equipment; UPS and emergency lights, warning lights and miner's lamps (the best safety); alternative The 3V disposable lithium battery and the 9V nickel-cadmium or nickel-metal hydride rechargeable battery in the camera (the same size); Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
