摘要
尖晶石型锰酸锂具有原材料丰富、易制备、环境友好、比容量高、循环性能好、充放电电压高等优点被认为是最有发展潜力的锂离子电池正极材料之一。但在充放电过程中较差的循环性能成为制约其产业化的主要因数。掺杂能有效地抑制容量衰减改善循环性能。综述了尖晶石LiMn2O4在阳离子掺杂,阴离子掺杂及复合掺杂方面的研究进展。
Spinel lithium manganate has been considered as a promising anode material for lithium ion batteries, since its abundant resources, simple synthesis process , low cost, no pollution, high specific capacity, excellent cycle performance and high charge-discharge voltage. However, the bad circulating performance restricted it to be commercialized. Doping was an effective method to improve the circulating performance. The research progress about the cation, anion and compounded doping process of LiMn2O4 were summarized.
