Abstract

The synthesis of Al2O3coated and uncoated LiMn2O4 by solidstate method and fabrication of LiMn2O4/graphite battery were described The structure and morphology of the powders were characterized by Xray diffraction XRD and scanning electron microscopy SEM respectively The electrochemical and overcharge performances of Al2O3coated and uncoated LiMn2O4 batteries were investigated and compared The uncoated LiMn2O4 battery shows capacity loss of 165 after 200 cycles and the coated LiMn2O4 battery only shows 125 after 200 cycles The uncoated LiMn2O4 battery explodes and creates carbon MnO and Li2CO3 after 3C/10 V overcharged test while the coated LiMn2O4 battery passes the test The steadier structure polarization of electrode and modified layer are responsible for the safety performance
