| 摘 要： | 文献中对LiCoO2材料的表面包覆已经进行大量的报道,清晰显示LiCoO2的表面改性对材料循环性能产生了重要正性效应。然而,材料的包覆原理和作用机制直到目前仍然模糊不清,没有一个确定统一定论。采用溶胶-凝胶法,结合TiO2与LiCoO2体相反应的研究结果,详细地研究了TiO2对LiCoO2的包覆效应,建议了可能包覆原理和作用机制。 |

| Abstract: | Recently,a lot of efforts were dedicated to the investigation on TiO2-coated LiCoO2,indicating that the surface-coating produced remarkable improvement in cycle ability.However,the working mechanism of surface-coating was still unclear so far.In this work,in combination with the study on the phase thermal stability of coating materials against LiCoO2,TiO2-coated LiCoO2 was investigated in detail by a sol-gel coating route and further a possible coating process and working mechanism of coating materials were proposed. |
| Keywords: | TiO2 LiCoO2 surface-coating lithium ion battery |
