The quality 48V 200Ah 10kwh Powerwall LiFePO4 battery is a lithium ion battery using lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material.

quality 48V 200Ah 10kwh Powerwall LiFePO4 battery
During the charging process, some of the lithium ions in the quality 48V 200Ah 10kwh Powerwall LiFePO4 battery are released, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of chemical reactions. During the discharge process, lithium ions come out from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy for the outside world.

The quality 48V 200Ah 10kwh Powerwall LiFePO4 battery high energy density
According to reports, the energy density of the square aluminum shell lithium iron phosphate battery 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 are made larger, or 185Wh/kg can be achieved.
The quality 48V 200Ah 10kwh Powerwall LiFePO4 battery 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 charging, squeezing, and acupuncture.
The quality 48V 200Ah 10kwh Powerwall LiFePO4 battery 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 1,000 cycles of ternary batteries. The cycle life of long-life lead-acid batteries is about 300 times.
