Abstract:

Lithium iron phosphate (LiFePO4) electrode material has the advantages of high specific capacity, stable operating voltage, low cost and environmental friendliness. It is regarded as an ideal cathode material for lithium ion batteries and is one of the main cathode materials for electric vehicles. However, the performance of LiFePO4 batteries decreases significantly at low temperatures, limiting their use in winter and cold regions. The researchers analyzed the reasons and proposed some solutions. This mini-review summaries four methods for performance improve of LiFePO4 battery at low temperature: 1)pulse current; 2)electrolyte additives; 3)surface coating; and 4)bulk doping of LiFePO4.

Key words: lithium-ion battery, lithium iron phosphate, low temperature performance, pulse current, impedance
