Microanalysis of the Substances in Positive and Negative Electrodes of a LiMn2O4 Battery for Road Vehicles under Over-charge and Over-discharge

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