Abstract

Se/KB composite was synthesized by heat-treatment,respectively,using super conductive ketjen black(KB) as carrier of element selenium(Se).The electrochemical performance of Se/KB composites was investigated.The phase and electrochemical properties of Se/KB composite were analyzed by XRD,SEM,EIS and galvanostatic charge-discharge tests.The results showed that Se/KB composite owned better specific capacity and cycle performance.At 0.2C,the initial discharge capacity reached 665.3mAh/g,even after 30 cycles,the composite can maintain a capacity of 334.7mAh/g and coulombic efficiency of 97.1%.
