【摘要】 综述了近年来掺杂锂离子正极材料尖晶石LiMn2O4的元素及方法,阐述了在锂离子正极材料LiMn2O4中掺杂钴、铬、镍、铝、稀土、钒后对材料性能的影响.结果表明,掺杂均不同程度地改善材料的循环稳定性,但对容量大都产生不利影响.更多还原

【Abstract】 Recent studies on spinel LiMn 2 O 4 doping other ions as cathode materials for Li-batteries were reviewed.The method of doping cobalt,chromium,aluminum,rare earths and other elements to the materials and their effects on the performances of materials were discussed in details.The result showed that doping can improve the cyclic stability,but will cause a negative effect on capacity.更多还原
