通过在其颗粒表面涂覆一层涂层，大大提高了颗粒尺寸为的带电材料的热稳定性。在常温下加热制备的复合材料的热分解起始温度为IS，而裸露样品的起始热分解温度为IS。此外，涂层还显著提高了充电截止时的循环容量保持率。这些结果表明，涂层有效地延缓了与电解液的分解反应，并在循环中保持了其结构的稳定性。©1999电化学会
A significant improvement in thermal stability of the charged with a particle size of has been achieved by coating its particle surface with . An onset temperature for thermal decomposition of the prepared by heating at was , whereas that of the bare is . In addition, the coating also improved the capacity retention on cycling at charge cut‐off significantly. These results appear to indicate that the coating is effective in retarding the decomposition reaction of with the electrolytes as well as sustaining its structural stability on cycling. ©1999 The Electrochemical Society
