Analysis of the advantages of ladder iron phosphate lithium ion batteries compared to traditional lead-acid batteries

Advantages of cascade lithium iron phosphate batteries compared to traditional lead-acid batteries ●High temperature resistance: lead-acid batteries work stably at a temperature range of 25～28℃, rising temperature will damage the battery and reduce battery life; ●High energy density: lithium iron phosphate Ion battery product weight ratio energy can exceed 130Wh/kg (0.2C, 25℃), volume ratio energy is 210Wh/L; lead-acid battery product weight ratio energy is 32～37Wh/kg (0.2C, 25℃), volume ratio Energy is 70Wh/L; ●High current charge and discharge performance: Lithium iron phosphate battery can charge and discharge high current 2C quickly, and the starting current can reach more than 5C. Lead-acid batteries do not have this performance now. Therefore, the charging time of the lithium iron phosphate battery is short; ●Green and environmental protection: The lithium iron phosphate battery does not contain any heavy metals and rare metals (the nickel-hydrogen battery requires rare metals), non-toxic (SGS certification passed); but there are in lead-acid batteries A large amount of lead, if improperly handled after it is discarded, will still cause secondary pollution to the environment. ●The cascade utilization power lithium ion battery has a long service life and many cycles. After cascade utilization, it can theoretically still have an actual life of 6 years and an actual cycle number of 400 to 2000 times, which is compared with the 3 to 6 years of the traditional lead-acid battery. , The actual number of cycles of 200 times has been greatly improved; ●Strong high temperature resistance, lithium-ion batteries can meet the use of extreme conditions below 45℃, and the current upper limit of lead-acid batteries commonly used in communication base stations is only 35℃; ●Charge-discharge conversion High efficiency, the energy conversion efficiency of cascade lithium iron phosphate batteries is 10% to 15% higher than that of lead-acid batteries.
