What are the advantages and disadvantages of lithium iron batteries for electric vehicles

Advantages of lithium iron batteries for electric vehicles (1) High energy density: nominal voltage is 3.2V, energy density is about 4 times that of lead-acid batteries, small in size and light in weight; (2) Strong safety: lithium iron phosphate cathode material It has good electrochemical performance, the charging and discharging platform is very stable, the structure is stable during the charging and discharging process, the battery does not burn, does not explode, and the safety is good; (3) Good high temperature performance: the battery works normally at an external temperature of 55°C; (4) High power output: standard discharge is 0.2C, can be charged and discharged at 3C; (5) Long cycle life: 1C charge and discharge at room temperature, the capacity of the monomer is still greater than 80% after 2000 cycles; (6) Environmental protection: the entire processing process is clean and free Toxic, all raw materials are non-toxic. The shortcomings of electric vehicle iron-lithium batteries will have the risk of explosion. When the lithium battery is charged and discharged with high current, the internal temperature of the battery continues to heat up, the gas that appears during the activation process expands, the internal pressure of the battery increases, and the pressure reaches a certain level, such as the outer shell is scarred. , It will break, causing leakage, fire, or even explosion.
