MgAl2O4 spinel doping into cathode materials LiMn2O4 was used to improve the cyclic performance of the cathode. X-ray analysis results showed, when MgAl2O4 precursors were mixed with LiMn2O4 and sintered at 770 ℃ for 12 hour, MgAl2O4-LiMn2O4 mulriple spinel with the same physical characteristics as ...
