摘要

A simple sol-gel method was applied to synthesize LiMn(1-x)FexPO4 (x=0-0.5). The kinetics of LiMn(1- x)FexPO4 was studied by chemical delithiation experiment and EIS measurements. The results showedthat the LiMn0.6Fe0.4PO4 has the fastest conversion rate from LiMn(1-x)FexPO4 to Mn(1-x)FexPO4 whichmight be related to the best rate capability among all these samples. The electrochemical tests showed-1 -1 -1 -1 that the discharge capacity for it is about 130 mAhg , 100 mAhg , 80 mAhg and 60 mAhg at 0.1 C,0.5 C, 1 C, and 2 C respectively.
