摘要 本文通过原位生长法制备了ZIF-8/CNT复合材料,并通过离子交换法优化合成了钴掺杂的ZIF-8/CNT,以此为模板制备了ZnCoS/CNT复合材料。同时本文还利用Fe-MOF/CNT复合材料制备其衍生的Fe_(2)O_(3)/CNT复合材料。进一步组装的ZnCoS-CNT//Fe_(2)O_(3)-CNT不对称型超级电容器,在功率密度为749.1 W·kg^(-1)时,达到46.3 Wh·kg^(-1)的高能量密度。在10 A·g^(-1)的电流密度下循环5000次充放电测试,仍保持了83.3%的容量。 In this paper, ZIF-8/CNT composites were prepared by in-situ growth method, and cobalt-doped ZIF-8/CNT was optimized by ion exchange method, which was used as a template to prepare ZnCOS/CNT composites.When the power density is 749.1 W·kg^(-1),the high energy density of ZnCoS-CNT//Fe_(2)O_(3)-CNT is 46.3 Wh·kg^(-1).It’s capacity can still maintain 83.3%even after 5000 cycles at the current density of 10 A·g^(-1).
