Where is the advantage of equipment using lithium iron phosphate batteries?energy storage battery for solar system Vendor

　　Large voltage

　　Lithium iron phosphate battery voltage platform High: The average voltage of a single battery is 3.7V or 3.2V, which is convenient for the battery pack.

　　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. Lithium battery has a high energy density, which is about 6-7 times that of lead-acid batteries.

　　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.

　　Safe and environmentally friendly

　　Lithium iron phosphate battery does not contain any heavy metals and rare metals, safe, non -toxic and pollution, and is an absolute green environmentally friendly battery. During the entire production process of lithium iron phosphate materials, all raw materials are non -toxic and non -polluting.

　　Ultra -low temperature performance

　　In addition to the above advantages, battery manufacturers also develop new types of low-temperature iron phosphate batteries, which can discharge 0.5C at -40 ° C. The discharge capacity exceeds 60%of the initial capacity; 0.3C is discharged at -35 ° C. The discharge capacity More than 70%of the initial capacity. The vast majority of battery equipment is completely sufficient.
