摘　　要：介绍了在实验室用柠檬酸络合法合成尖晶石LiMn2O4的方法以及用上述材料制备的试验电池;用X射线衍射仪和扫描电镜分析了热处理条件对LiMn2O4粉末结构和形貌的影响;详细报道了试验电池在不同热处理温度和时间条件下的充放电特性和循环性能的试验结果。The synthetical method of spinel LiMn2O4 prepared by citric acid complex and the sample battery made of above-mentioned materials were introduced. The effect of heat treatement condition on structure and configuration of spinel LiMn2O4 were analyzed with X-ray diffraction and scanning electron microseopy. The charge-discharge characteristics and cycle performance of sample battery treated at different temperature and time were described in detail.
