【摘要】 报导了在７５０ ℃下合成尖晶石ＬｉＭｎ２Ｏ４ 的最佳时间为７２ｈ 。以Ｎｉ 取代部分Ｍｎ 后合成的ＬｉＭｎ２ － ｘＮｉｘＯ４ ，其首次的可逆容量有所下降，但循环性能提高。掺杂量ｘ 大于０１ 时，产物中存在杂质相ＮｉＯ，导致电化学性能下降。更多还原

【Abstract】 The optimistic heating time of spinel manganese oxide LiMn 2O 4 was 72 hours under 750 ℃ in air.The initial reversible capacity of the doped spinel oxide LiMn 2-x Ni xO 4 declined while the cycling performance improved.X-ray diffraction profiles indicated the existence of NiO in the products when the content of dopant Ni was above 0.1更多还原
