摘要

柔性全固态超级电容器作为便携式、可穿戴电子的储备电源备受青睐。利用印刷电子大面积、柔性化的独特优势可大大简化柔性电极的制作工艺，以活性炭为活性材料配制油墨，并结合导电银浆，采用丝网印刷方式套印制作了柔性超级电容器电极，并将PVA-H2SO4凝胶作为电解质涂覆在活性电极上组装成柔性共面超级电容器，测试其电化学性能。结果表明，丝印柔性超级电容器电极可成功应用于柔性共面超级电容器。当采用PVA-H2SO4凝胶作为电解质时工作电压可达0.8 V。当充放电电流为0.2 mA时，柔性共面超级电容器的面积比电容达到18 mF·cm-2。

Abstract

Flexible all-solid-state supercapacitors are favored as the backup power of the portable and wearable electronic devices. With the unique advantages of large-area and flexibility of printed electronics, the manufacturing process of flexible electrodes can be greatly simplified. In this paper, activated carbon is used as active material and flexible supercapacitor electrodes are prepared by screen printing technology using activated carbon ink and conductive silver ink. Then, the flexible supercapacitor is assembled with the electrode coated with PVA-H2SO4 gel and the electrochemical properties are measured. The results show that the printed supercapacitor electrode can be successfully applied to flexible in-plane supercapacitors. The working voltage achieves 0.8 V and the areal specific capacitance of the whole device achieves 18 mF·cm-2 at a charge-discharge current of 0.2 mA.

Key words： activated carbon; all solid state; printed electronics; supercapacitors
