Cycle life:

The oretically, lithium iron phosphate has an advantage in longevity.The olivine crystal structure is more stable, the expansion is lower and the electrochemical reaction is more stable.


Lithium-iron phosphate batteries have unparalleled safety advantages.Its positive electrode voltage is low, there is no similar to the ternary oxygen release thermal chain reaction, thermal stability temperature can reach more than 300℃, and ternary battery at about 150-200℃.


In terms of price, LiFePO4 has obvious advantages at present. The raw materials are relatively cheap and the domestic industrial chain is relatively mature.
