【摘要】 超大容量离子电容器又称电池型电容器，是一种介于静电电容器与二次电池之间的一种新型储能器件。它具有比静电电容器大得多的能量密度，又有比二次电池大得多的功率密度。适宜于短时大电流放电的情况下工作，可作为电动车辆的启动、制动电源，是解决电动车辆发展的瓶颈。笔者综述了超大容量离子电容器的储能原理、应用以及国内外的研究现状。更多还原

【Abstract】 Supercapacitors have very large capacitance. They are also called battery capacitors, for their high energy density and high power density. They are suitable for the applications where a large current is needed within a short period of time, such as power supplies for electric vehicles starting and braking. The principle and applications, home and abroad, are reviewed.更多还原
