摘要
近年来超级电容器作为一种储能装置备受关注,传统电极材料大多存在对环境有害、电荷储备性能较差的问题,因此开发一种能够快速充放电、绿色、环保友好的电极材料迫在眉睫.研究选取木质炭、菊花炭、钢炭(碳化炉烧)、竹炭和钢炭(土窑烧)5 种木、竹基碳材料,制备成木竹基电极,测试他们的电化学性能.结果表明,竹炭制成的竹基电极面积比电容可达 2 432 mF/cm2,具有较好的倍率性能,相比其他材料是最具发展潜力的木竹基电极材料.
Abstract
In recent years,supercapacitor has attracted widespread attention as an energy storage device.Traditional electrode materials often have issues relevant to environment and charge storage performance.Therefore,it is imminent to develop an environmentally-friendly green electrode material capable of rapid charge and discharge.This study selects five types of wood-and bamboo-based carbon materials,including wood charcoal,chrysanthemum charcoal,steel charcoal(furnace burned),bamboo charcoal,and steel charcoal(kiln burned)to prepare wood-and bamboo-based electrodes and then test their electrochemical performance,the results show that the bamboo-based electrode made from bamboo charcoal can achieve a specific area capacitance of 2 432 mF/cm2,showcasing a good rate performance.Compared to other materials,it is the most promising wood-and bamboo-based electrode material.
