二硼化钛在氟化钾溶液中的放电行为

摘要研究了二硼化钛电极在20%(质量分数)KF溶液中的放电性能及其影响因素。试验发现,当放电速率为100 mA/g时,二硼化钛电极总的放电容量可达2000 mA.h/g。二硼化钛电极在20%(质量分数)KF溶液中的放电曲线上出现了4个放电平台,结合循环伏安曲线、ICP及XRD等分析手段对相应的电化学过程进行了分析,提出了二硼化钛发生电化学氧化反应的可能机理。

Abstract： The discharge performance of TiB_2 electrode in 20% KF solution was studied in this paper.The experimental results showed that the total discharge capacity of TiB_2 electrode could reach(2 000) mA·h/g at a constant current rate of 100 mA/g.There are four discharge stages on the discharge curves of TiB_2 electrode,and their related electrochemical processes were analyzed by the cycle voltammograms,ICP and XRD, and the possible reacting mechanism of TiB_2 was discussed in detail.
