Characteristics of lithium iron phosphate battery

1. High energy density
According to reports, the energy density of 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 chip technology and capacity can be made larger, or 185Wh/kg can be achieved.
2. 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. It is still very safe under special conditions such as filling, extrusion, and acupuncture.
3. Long cycle life
The 1C cycle life of lithium iron phosphate batteries generally reaches 2,000 times, or even more than 3,500 times, while the energy storage market requires more than 4,000-5,000 times, ensuring a service life of 8-10 years, which is higher than the cycle of more than 1,000 times for ternary batteries Life, while the cycle life of long-life lead-acid batteries is about 300 times.
