Abstract
The low temperature performance of Li-ion batteries and LiFePO4/C composites was discussed. A conclusion that cathode material is the main limitation for the low temperature performance was come up, by comparing the low temperature performance of 18650 Li-ion batteries with LiMn2O4, LiNi1/3Co1/3Mn1/3O2 and LiFePO4/C as cathode materials. The low temperature performance results indicate the LiFePO4/C microstructure is the main factor influencing the low temperature performance of LiFePO4. A new LiFePO4/C with pomegranate-like spherical structure was proposed in this paper, which shows superior low temperature performance, which can be attributed to its uniform fine primary particles and smaller primary particles.
