With an 11Ah LiMn2O4 battery as the object of study, through disassembling the battery after normal charge and normal discharge as well as over-charge and over-discharge, and using such methods as x-ray diffraction and scanning electron microscope, this study explores the micro-changes that happened to the material for the anode and cathode of this lithium battery after over-charge and over-discharge, and provides the measures to prevent batteries from charge and discharge, so as to avoid potential safety problems during the use of lithium batteries.
