摘要
以硝酸锂、硝酸锰和尿素为原料，采用燃烧法制备尖晶石型ＬｉＭｎ２Ｏ４锂离子电池电极材料，并考察了锂和锰的比例、尿素用量、预置炉温、焙烧温度及焙烧时间等工艺条件对合成产物的组成结构及电化学性能的影响。最佳工艺条件下制备的产物具有纯净的尖晶石结构，均一的颗粒度及优良的电化学性能。
A new simplified technique(combustion method)was adopted to synthesize LiMn2O4 directly from lithium nitrate, manganese nitrate and urea. The influence of the Li/Mn ratio, the amount of urea, the preset furnace temperature, the calcining temperature and time was investigated. The resultant LiMn2O4 synthesized under the optimum synthesis conditions showed perfect spinel structure,uniform particle size and excellent electrochemical performance.
