几种LiFePO4正极材料的表征及电化学性能研究
Characterizing and study on electrochemical performance of LiFePO4 cathode materials
摘要
Abstract
The crystal inity, morphology, particle size and electrochemical performance of three kinds of LiFePO4 provided by three manufacturers were characterized by XRD, SEM, CV, EIS and constant current charge/discharge. The results show that these properties have great influences on the discharge capacity, cycle life and rate property of the batteries. Sample 1 has perfect crystal inity, and the secondary particle aggregated with nanoscale initial particles has proper size. Accordingly, 18650-type battery using sample 1 as the cathode material exhibits the highest specific capacity, the best cycle stability and the highest capacity retention when discharging at 8 .关键词
