What is a lithium iron phosphate battery? Introduction to the advantages of lithium iron phosphate batteries

by:Vglory      2021-05-13
Lithium iron phosphate battery is a type of lithium battery, which refers to a lithium battery that uses lithium iron phosphate as a positive electrode material. It is characterized by strong safety and stability, high temperature resistance and good cycle performance. Like the ternary lithium battery, the theoretical life of the lithium iron phosphate battery also exceeds 2000 charge and discharge cycles, and it can last for more than five years even if it is charged once a day. Generally speaking, the daily household charge is three days, and it can be used for about eight years. However, due to the poor low-temperature performance of lithium iron phosphate batteries, the life of lithium iron phosphate batteries will be relatively longer in the southern region.

Lithium iron phosphate battery has a high storage energy density, which has now reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries; 2. The service life is long, and the service life of lithium iron phosphate battery packs can reach more than 6 years. 3. The extra voltage is high (the single working voltage is 3.7V3.2V), which is approximately equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is convenient to form a battery power pack; 4. It has high power acceptance, among which electric cars The lithium iron phosphate battery used can reach the charging and discharging ability of 15-30C, which is convenient for high-intensity start-up speed; 5. The self-discharge rate is low, which is one of the most outstanding advantages of the battery, and it can usually achieve 1%/ At the end of the month, it is much lower than 25-30% of Ni-Cd and 30-35% of Ni and MH; 6. Light weight, the weight of lithium iron phosphate battery is about 1/5-1/ of that of lead-acid battery products under the same volume. 6;7. The upper and lower temperature has strong applicability, and it can be used under the condition of -20C-60C, and can be used in the environment of -45 degrees through the process of disposal.
