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。The discharge performance of TiB2 electrode in 20% KF solution was studied in this paper. The experimental results showed that the total discharge capacity of TiB2 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 TiB2 electrode, and their related electrochemical processes were analyzed by the cycle voltammograms, ICP and XRD, and the possible reacting mechanism of TiB2 was discussed in detail.
