AbstractThe lithium-ion battery cathode material spinel LiMn_2O_4 and LiMn_(1.92)Mg_(0.08)O_(3.84)Br_(0.16) samples were synthesized by sol-gel method,the effects of Mg and Br co-doping on the structure,morphology,chemical component and electrochemical performanc
Other Abstract通过溶胶凝胶法制备出LiMn_2O_4和LiMn_(1.92)Mg_(0.08)O_(3.84)Br_(0.16)锂离子电池正极材料,并用XRD、SEM、XPS、充放电测试和CV对其结构、形貌、化学成份以及电化学性能进行了研究。结果表明,Mg、Br的掺杂未改变LiMn_2O_4的结构。在0.5 C倍率下,LiMn_(1.92)Mg_(0.08)O_(3.84)Br_(0.16)的放电比容量为119 m Ah/g,与LiMn_2O_4相比,其首次放电比容量提高了3.6%,循环100次后,Li Mn1.92M
