摘要: 研究了人工施加的无机固体电解质晶体膜对锂碳负极电池性能的影响作用,结果表明碳电极的容量及首次充放电效率相对于未改性电极都得到了一定程度的提高,显示了以这层外界人工施加的晶体膜替代由电极体系本身所形成的钝化膜之有效性.扫描电子显微镜的研究直观地显示了这层人工施加膜的均匀、致密性质.

Abstract: The improving effect of solid electrolyte film artificially imposed on carbon electrode was investigated. The result showed that both the charge/discharge capacity and first charge/discharge efficiency, to a certain extent, were enhanced, and the result also suggested the effectiveness of the substitution of the artificially imposed solid electrolyte film for the inherent passivating film which was formed on the surface of the carbon electrode while inserted in the electrolyte during charging or discharging. The Scanning Electron Microscope result displayed the compact and well defined morphology of the artificially imposed crystalline film.

Key words: Lithium ion battery, Carbon material, Anode, Modification, Artificially imposed solid electrolyte film
