摘要

以酸化后的高导电柔性碳布为基底,通过电化学沉积及辅助热处理技术在碳布表面均匀地生长了规整排列的四氧化三钴(Co3O4)纳米片材料,纳米片厚度约为15nm,片层之间相互交织,形成三维网络多孔结构。这种独特的结构不仅增加了Co3O4纳米材料的有效利用率,而且缩短了电解质离子的传输通道,加速了其倍率性能。期待该材料成为组装高性能柔性电容器器件的备选电极材料。

Abstract

Flexible carbon cloth with high conductivity used as the substrate and after acidification,cobalt trioxide(Co3O4) nanosheets arrays were growing on the surface of the carbon cloth through electrochemical deposition and auxiliary thermal technology.The thickness of the Co3O4 nanosheets was about 15 nm,and the layers were interwoven to form a 3D network porous structure.This unique structure not only increased the effective utilization of Co3O4 nanomaterial,but also shortened the transport channel of electrolyte ions and accelerated its rate performance.The material was expected to be an alternative electrode material for assembling high performance flexible capacitor devices.
