Synthesis and Electrochemical Properties of LiAl0.1Mn1.9O4 by Sol-gel Method

摘要

Spinel-type LiAl0.1Mn1.9O4 have been synthesized by sol-gel method. We found that Al-doped LiMn2O4 can overcome capacity fading, showed relatively good cycling performances. The structural and electrochemical properties of LiAl0.1Mn1.9O4 was investigated by X-ray diffraction (XRD),charge/discharge.Electrochemical test of the Al-doped LiAl0.1Mn1.9O4 showed excellent rate capability, better reversibility than that of no Al-doped LiMn2O4.
