摘要

摘要:针对全固态平面超级电容器性能偏低的问题，采用一种由在硅片上直接生长的方法制备出石墨烯薄膜作为电极，利用双电层超级电容器工作原理，采用PVA/H2SO4凝胶电解质，制备得到石墨烯基全固态平面超级电容器。循环伏安测试结果表明：该超级电容器具有双电层电容特性。循环伏安曲线没有氧化还原峰，说明双电层电容完全提供电极的容量。当扫描速率为50mV/s时，该超级电容器的循环伏安特性较好，面积比电容为290.24μFcm-2，能量密度为22.68μWhcm-2。为平面微型超级电容器的研究提供了重要参考。

Abstract

Abstract:For a problem of low performance of planar supercapacitors

graphene films were prepared by a method of direct growth on silicon wafers as electrodes

and PVA/H2SO4 is used as gel electrolyte. Graphenebased all-solidstate planar supercapacitor was prepared with working principle of electric double layer capacitor. The results of cyclic voltammetry showed that the supercapacitor had characteristics of double layer capacitance

and there was no redox peak in the cyclic voltammetry curves

indicating that the electric double layer provided capacity of electrodes. When the scanning rate was 50mV/s

the supercapacitor had better performance of cyclic voltammetry. The area capacitance was 290.24μFc-2 and the energy density was 22.68μWhcm-2. This paper provides an important reference for further research on planar micro-supercapacitors.
