1. High energy density

It is reported that the energy density of the Lithium iron phosphate battery with square aluminum shell produced in mass in 2018 is about 160Wh/kg. In 2019, some excellent battery manufacturers will be able to reach the level of 175-180Wh/kg, and some powerful manufacturers will adopt lamination process and have larger capacity, or can reach 185Wh/kg.

2. Good safety performance

The electrochemical performance of the positive electrode material of Lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the battery structure will not change during the charging and discharging process, and will not burn or explode, and it is still very safe even under special conditions such as short circuit, overcharge, extrusion, acupuncture, etc.

3. Long cycle life

The 1C cycle life of Lithium iron phosphate battery is generally up to 2000 times, or even more than 3500 times. For the energy storage market, it is required to reach more than 4000-5000 times, ensuring a service life of 8-10 years, which is higher than the cycle life of ternary battery for more than 1000 times, while the cycle life of long-life lead-acid battery is about 300 times.
