摘　　要：介绍了高储能密度电容器研究的发展及现状 ,讨论了复合介质薄膜、分割电极金属化膜和复合喷金层技术等新的研究方向。研究表明 ,优化结构设计、选择合适的介质膜(如金刚石复合膜 )及改善端部的接触 (如增大喷金与电极的接触面及改善电场分布 )可有效地提高电容器的性能及寿命 ,储能密度 2～ 3k J/ L 的电容器可望投入使用。The evolution of high energy density capacitor is described briefly. Due to the adoption of metallization technology, the capacitor energy density has risen greatly, from tens of joules/liter to almost 1k joules/liter. Some current research trends, including hybrid dielectric film, segmented electrode metallized film and end spraying employing plural materials, are also presented. With the development of material science and the application of new materials, the capacitor energy density is promising to reach as high as 2k^3k joules/liter.
