The characteristics of lithium iron phosphate battery.solar energy storage system battery pack lithium

　　1) High energy density

　　The energy density of a square aluminum -shaped aluminum -shaped iron phosphate battery in 2018 is about 160Wh/kg. The single energy density of lithium iron phosphate batteries produced in 2019 reaches the level of 175 to 180Wh/kg. The single energy density of lithium iron phosphate batteries reaches 185Wh/kg.

　　2) Good safety performance

　　The electrochemical performance of the positive electrode material of lithium iron phosphate batteries 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 discharge process, it will not burn and explode, and even in short -circuit, over -charging Under special conditions such as squeezing and acupuncture, it is still very safe. Because the thermal output temperature of lithium iron phosphate batteries is generally above 500 ° C, the ternary lithium battery is lower than 300 ° C, and the heat loss temperature of some high -nickel batteries is even lower than 200 ° C. The risk of spontaneous combustion during fast charging is low.

　　3) Long cycle life

　　Because the charging cycle of lithium iron phosphate battery is greater than 3500 times, it will begin attenuation, which means that its service life can be as long as about ten years, but the number of three -yuan lithium battery charging discharge cycle is only 2000 times, which means that it uses its use Life is only 6 years, and the gap between the two can be seen. 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 to 5,000 times. Life, and the cycle life of long life lead -acid batteries is about 300 times.

　　4) Safety and environmental protection

　　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.

　　5) The cost of manufacturing is lower, because the lithium iron phosphate battery does not have valuable metals, so the production cost is low. On the other hand, the ternary lithium battery is high due to cobalt metals, resulting in high cost.
