What are the advantages and disadvantages of iron-lithium batteries?

Introduction to iron lithium battery

The iron- lithium battery is a kind of battery in the lithium battery family, and the positive electrode material is mainly lithium iron phosphate material, which is also referred to as lithium iron battery. Compared with traditional lead-acid batteries, lithium-ion batteries have significant advantages in terms of operating voltage, energy density, and cycle life.

Advantages of electric vehicle iron lithium battery

(1) High energy density: the nominal voltage is 3.2V, the energy density is about 4 times that of lead-acid batteries, and the volume is small and the weight is light;

(2) Strong safety: lithium iron phosphate cathode material has good electrochemical performance, the charging and discharging platform is very stable, the structure is stable during charging and discharging, the battery does not burn, does not explode, and has good safety;

(3) Good high temperature performance: the battery works normally when the external temperature is 55 °C;

(4) High power output: standard discharge is 0.2C, 3C can be charged and discharged;

(5) Long cycle life: 1C charge and discharge at room temperature, the capacity of the monomer after 2000 cycles is still greater than 80%;

(6) Environmental protection: The whole production process is clean and non-toxic, and all raw materials are non-toxic.

There is a danger of explosion. When the lithium battery is charged and discharged at a high current, the inside of the battery continues to heat up. The gas generated during the activation process expands, the internal pressure of the battery increases, and the pressure reaches a certain level. If the outer casing is scratched, it will rupture, causing Leakage, fire, or even explosion.
