discharging platform

The charging and discharging result indicated that when the alloying element are many ( M: V ≥ 0.25:1.75), the material charging and discharging platform reduces, this causes the material the platform to be stable, which is advantageous in using for the battery charging and discharging.

充放电结果表明，当掺杂元素多时（M：V≥0.25：1.75），材料的充放电平台减少，这就使得材料的平台更加稳定，有利于用电池充放电，改善充放电效率。

The batteries showed higher specific capacity on high voltage charge-discharge but decreasing rapidly during the cycling. Cathode controls the charging-discharging characteristics, including discharging platform.

高电位下恒流充放电循环，放电比容量虽增加但衰减很快。阴极在很大的程度上控制电池的充放电性能，阴极的放电电位控制着电池的放电平台；
