The rapid development of the communications industry has led to the continuous increase of various equipment and the continuous increase of required power demand. The communications industry is facing huge cost pressure and pressure to increase the incidence of failures. Lithium iron phosphate (LiFePO4) battery is the most important energy storage link in the communication industry. It can effectively reduce costs and reduce power failures in communication base stations.

　　Compared with traditional lead-acid batteries, the application of lithium iron phosphate batteries for communication can better meet the needs of energy saving, material saving and land saving.

　　The main advantages of lithium iron phosphate are:

　　Regardless of the volume ratio energy or weight ratio of lithium iron phosphate batteries, lithium iron phosphate batteries are more than 3 times higher than lead-acid batteries. The same is the 12V100ah specification. The lithium iron phosphate battery weighs only about 10kg, but the lead-acid battery has a weight of about 30kg.

　　The cycle life of a lithium iron phosphate battery reaches about 2000 times, and the cycle life of a lead-acid battery is only about 500 times. The service life of the lithium iron phosphate battery is 3 to 5 times that of the lead-acid battery, which greatly reduces the long-term use cost of the LiFePO4 battery and saves the after-sales maintenance and repair costs of later replacement and maintenance.

　　LiFePO4 batteries have excellent high temperature resistance, which can double the battery life of outdoor stations of communication base stations, reduce battery maintenance and replacement costs, and improve system reliability.

　　LiFePO4 battery can still discharge to more than 90% of its full capacity when discharged at a rate above 3C. The advantages of high power and deep discharge can effectively reduce the total capacity of the current UPS backup battery
