Lifepo4 Battery Pack

Introduction of Lifepo4 Battery Pack 

Lifepo4 battery pack is a kind of lithium ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single unit is 3.2V, and the charge cut-off voltage is 3.6V~3.65V.
During the charging process, part of the lithium ions in the lithium iron phosphate are extracted, 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 the chemical reaction. During the discharge process, lithium ions are extracted 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. 

Features of Lifepo4 Battery Pack

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 Lifepo4 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 Lifepo4 battery 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.

Lifepo4 is the more efficient technology batteries , knocking out traditional lead acid batteries . Lifepo4 battery has the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect. VODNO, one of the leading Lifepo4 battery pack manufacturer, provides a complete line of 12 ,24 and 48 volt batteries for use inRVS , Boats , Evs and off-grid applications and much more.
