以MoS2修饰的3D打印还原石墨烯气凝胶制备微型超级电容器电极
The production of electrodes for microsupercapacitors based on MoS2-modified reduced graphene oxide aerogels by 3D printing
摘要
Abstract
Micro-supercapacitors(MSCs)are of interest because of their high power density and excellent cycling performance,offering a broad array of potential applications.However,preparing electrodes for the MSCs with an extremely high areal capacit-ance and energy density remains a challenge.We constructed MSC electrodes with an ultra-high area capacitance and a high energy density,using reduced graphene oxide aerogel(GA)and MoS2 as the active materials,combined with 3D printing and surface modi-fication.Using 3D printing,we obtained electrodes with a stable macro structure and a GA-crosslinked micropore structure.We also used a solution method to load the surface of the printed electrode with molybdenum disulfide nanosheets,further improving the electrochemical performance.The surface capacitance of the electrode reached 3.99 F cm-2,the power density was 194 μW cm-2,and the energy density was 1 997 mWh cm-2,confirming its excellent electrochemical performance and cycling stability.This work provides a simple and efficient method for preparing MSC electrodes with a high areal capacitance and energy density,making them ideal for portable electronic devices.关键词
