Higher energy density
According to reports, the energy density of the square aluminum-shell lithium iron phosphate batteries mass-produced in 2018 is about 160Wh/kg. In 2019, some excellent battery manufacturers can probably achieve the level of 175-180Wh/kg. The film technology and capacity can be made larger, or 185Wh/kg can be achieved.
Good safety performance
The electrochemical performance of the cathode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and it will not burn and explode. It is still very safe under special conditions such as filling, squeezing, and acupuncture.
Long cycle life
The 1C cycle life of lithium iron phosphate batteries is generally up to 2000 times, or even more than 3,500 times, and the energy storage market requires 4000-5000 times or more, guaranteeing a service life of 8-10 years, which is more than 1,000 cycles of ternary batteries Life span, and the cycle life of long-life lead-acid batteries is about 300 times.
