Master the three major characteristics of lithium iron phosphate battery.48v solar power energy storage power wall

　　During the charging process, some lithium ions in lithium iron phosphate were removed, passed through the electrolyte to the negative electrode, and embedded in the negative electrode carbon material. At the same time, the electrons were released from the positive electrode, reached the negative electrode from the external circuit to maintain the balance of chemical reactions.

　　During the discharge process, the lithium ion was removed from the negative electrode, reached the positive electrode through the electrolyte, and the electrons were released at the same time.

　　Lithium iron phosphate batteries have the advantages of high working voltage, high energy density, long circular life, good safety performance, small self -discharge rate, and no memory effect.

　　High energy density

　　According to reports, the energy density of a square aluminum-shaped iron phosphate battery in 2018 is about 160Wh/KG. In 2019, some excellent battery manufacturers can achieve the level of 175-180Wh/kg. The film and capacity are large, or they can achieve 185Wh/kg.

　　Good safety performance

　　The electrochemical performance of the positive electrode material of the lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharge platform. Therefore, the structure of the battery will not change during the charging and discharge process, and it will not burn and explode. Under special conditions such as charging, squeezing, acupuncture, etc., it is still very safe.

　　Long cycle life

　　Lithium iron phosphate battery 1C has a 1C cycle life of 2000 times, or even more than 3500 times, and the requirements for the energy storage market will reach 4,000-5,000 times. It is guaranteed to use the service life of 8-10 years. Life, and the cycle life of long life lead -acid batteries is about 300 times.
