本文详细介绍了工业化的超级电容器所用材料，同时对超级电容器材料的研究趋势做了一定的分析。Electrochemical capacitors (ECs) have come to be called ‘‘supercapacitors,’’‘‘ultracapacitors,’’ and ‘‘power capacitors’’ depending on its charge mechanismor active electrode material used for construction. The expression‘‘supercapacitor’’ was originally coined by Nippon Electric Company (NEC),who first successfully marketed the device as SuperCapacitor , made fromcarbon material, while ‘‘ultracapacitor’’ stems from devices designed for useby the U.S. military using ruthenium and tantalum oxides. A clear termhas yet to be defined in either research or industry; regardless, the term‘‘electrochemical supercapacitor’’ will be used in this text to describe all materialsthat store energy by means of capacitance. Electrochemical supercapacitorsuse two distinctly different charge mechanisms to develop capacitance: electricdouble-layer capacitance through an electrostatic charge development betweenthe electrode/electrolyte interfaces, and pseudocapacitance developed from highlyreversible Faradaic reactions processes occurring at specific potentials [1–4].The resulting capacitors are called electric double-layer capacitors (EDLC) andpseudo-capacitors.下载提醒：APP中打开可直接下载，点击下载01-Yu_Electrochemical-supercapacitors.pdf返回小木虫查看更多
