摘要:
LiFePO4 and LiFePO4/C cathodes were prepared by freeze-drying technology. The as-prepared powders were characterized and capacities of cathodes were investigated LiFePO4 and LiFePO4/C had small particle size and narrow particle size distribution, the particle size of LiFePO4/C (174 5 nm) was smaller than that of LiFePO4. The capacity of LiFePO4/C was higher than that of LiFePO4 under different ratio, the capacity of fading was not obvious on their cycle performances. both of them had better cycle performance.
