Author:
Lithium iron phosphate battery cathode material electrochemical performance is relatively stable, which determines that it has a smooth charging and discharging platform, therefore, in the process of charging and discharging the structure of the battery will not change, will not burn and explode, and even in the short-circuit, overcharging, extrusion, pinprick and other special conditions.
1. Higher energy density
It is reported that in 2018, the mass production of square aluminum shell lithium iron phosphate battery monomer energy density is about 160Wh/kg, and in 2019, some excellent battery manufacturers can probably achieve the level of 175-180Wh/kg, and individual powerful manufacturers use the stacking process, the capacity to do more, or can do 185Wh/kg.
2. Good performance
Lithium iron phosphate battery cathode material electrochemical performance is relatively stable, which determines that it has a smooth charging and discharging platform, therefore, in the process of charging and discharging the structure of the battery will not change, will not burn and explode, and even in the short-circuit, overcharging, extrusion, pinprick, and other special conditions, it is still very.
3. Long cycle life
Lithium iron phosphate battery 1C cycle life is generally up to 2,000 times, or even more than 3,500 times, and for the energy storage market requirements to reach more than 4,000-5,000 times to ensure that 8-10 years of service life, higher than more than 1,000 times ternary batteries cycle life, and long-life lead-acid batteries in the cycle life of about 300 times.
