溶胶－凝胶－酯化方法是通过金属离子与多元有机酯形成均一的螯合物。在较低的温度（＜２５０℃）下形成尖晶石型ＬｉＭｎ２Ｏ４正极材料。采用该方法制备的ＬｉＭｎ２Ｏ４具有很好的电化学活性。Ｌｉ／ＬｉＭｎ２Ｏ４二次电池首次充放电容量超过１３０ｍＡｈ／ｇ，循环１０次以后容量仍然保持在１２０ｍＡｈ／ｇ的较高水 The sol-gel-esterification process is the formation of a uniform chelate with a polybasic organic ester through a metal ion. Spinel LiMn2O4 cathode material was formed at lower temperature (<250 ℃). The prepared LiMn2O4 has good electrochemical activity. Li / LiMn2O4 secondary battery first charge and discharge capacity of more than 130mAh / g, after 10 cycles capacity remained at 120mAh / g higher water
