Lithium iron phosphate full name should be lithium iron phosphate lithium-ion battery, referred to as lithium iron phosphate battery. Because of its performance is particularly suitable for power applications, so called power battery, that is, lithium iron phosphate power battery.
LiFePO4 battery internal structure:
LiFePO4 material is used as the cathode cost. At present the cathode materials used in lithium-ion battery are: LiCoO2、LiMn2O4、LiNiO2 and LiFePO4. Among the metal elements constituting the positive electrode material of the battery, cobalt (Co) is the most expensive and has a small storage amount. Ni, Ni and Mn are cheaper and Fe is the cheapest. The price of the cathode material is also consistent with the prices of these metals. Therefore, the use of LiFePO4 cathode material made of lithium-ion battery should be the cheapest.
The advantages and disadvantages of lithium iron phosphate battery as the power of new energy vehicles:
Pros: safety and longer life; Does not contain any heavy metals and rare metals (raw materials, low cost); No memory effect; Heat – resisting; Can easily pass the needle test.
Cons: low tap density and compaction density; poor low temperature performance; small capacity; same capacity: heavy weight and large volume; No recyclable value.
