以Ｌｉ２ＣＯ３和Ｍｎ（ＮＯ３）２为原料，以聚丙烯酰胺为高分子网络剂制得前驱体后，用微波加热技术合成了纳米晶尖晶石ＬｉＭｎ２Ｏ４粉体，通过循环伏安及充放电技术对其进行电化学性能测试表明，该材料的电化学比容量为 １２０ｍＡｈ／ｇ；循环 ５０次后衰减率为 ４．７％；通过 ＳＥＭ及ＸＲＤ分析其微观形貌表明，该材料不仅相纯度高，而且颗粒粒度近于纳米级，有利于Ｌｉ＋的嵌入／脱嵌．本文所提供的微波一高分子网络技术不仅为合成具有优良性能的锂锰尖晶石氧化物材料提供了一个新方法，而且为合成其他类型高性能氧化物陶瓷材料提供了一条新思路．
After Li2CO3 and Mn (NO3) 2 were used as raw materials and polyacrylamide was used as the polymer network agent, the nanocrystalline spinel LiMn2O4 was synthesized by microwave heating technique. The cyclic voltammetry and charge-discharge The results of electrochemical tests show that the material has a specific electrochemical capacity of 120 mAh / g and a decay rate of 4.7% after 50 cycles. The SEM and XRD results show that the material has high phase purity, Moreover, the grain size is near nanometer, which is good for embedding / deintercalation of Li +. The microwave-to-macromolecule network technology provided in this article not only provides a new method for synthesizing lithium manganese spinel oxide materials with excellent properties, but also provides a new idea for synthesizing other types of high performance oxide ceramic materials.
