The reasons of the capacity attenuation have primarily to accompany with the Li~+ ion embedding material on discharge process the effect of Jahn-Teller of the occurrence, the deliquescence of the cathode manganese in the material and the decomposition of the electrolyte.

在锂离子电池众多的正极材料中，尖晶石型LiMn_2O_4化合物，由于其原材料资源丰富，价格低，环境污染小，合成工艺简单，成为最有希望取代LiCoO_2的材料，但LiMn_2O_4存在容量衰减大，循环寿命短等问题，阻碍了其商品化应用；容量衰减的原因主要有在放电过程中伴随着Li~+离子嵌入发生的Jahn-Teller效应，正极材(来源：AacBCbd论4b文网www.abclunwen.com)料中的锰的溶解和电解液的分解。

In chapter three, various theories and experience on the dispersion of nano-powders proposed by former researchers were generalized and reviewed. Technical standards and experimental process for determining technological parameters were suggested for the dispersion of nano-scaled metal oxides in aqueous medium according to their surface wettability, surface charge, the dependence of surface charge on pH and the compatibility of surfactants with pH and pH adjusting agents. Based on these suggested standards and experimental method, highly stable and dispersive aqueous suspensoid of nm-ZnO, nm-TiO〓, nm-Co〓O〓 and nm-MnO powders were prepared successfully and surface modification on these nano-powders was also achieved.

本文第三章通过大量的文献调研，归纳总结了前人在纳米粒子分散技术方面的理论和经验，并在此基础上根据纳米氧化物粉体的表面润湿性、表面电性及其与分散介质pH值的关系、表面活性剂及其与pH调节剂的配伍关系设计了纳米氧化物水分散体系的工艺规范以及确定工艺参数的通用实验步骤，成功地制备了纳米氧化锌、纳米二氧化钛、纳米氧化钴和纳米氧化锰的高稳定分散悬浮液并实现了干粉体的表面改性，为纳米材料在氧化锌压敏电阻中的应用创造了第二个前提条件。
