电化学电容器（EC）也称为“超级电容器”或“超级电容器”，其将能量存储在电化学双层的电场中。高表面积电极的使用导致极大的电容。EC的单电池电压通常限于1-3 V，这取决于所使用的电解质。用于低压电子应用的小型电化学电容器已在市场上销售多年。需要具有高电压和改进的能量和功率密度的大型EC的不同应用正在讨论中。本文介绍了电化学电容器的基本原理、性能、特点、应用现状和发展前景。(C)2000爱思唯尔科技有限公司版权所有。
Electrochemical capacitors (EC) also called 'supercapacitors' or 'ultracapacitors' store the energy in the electric field of the electrochemical double-layer. Use of high surface-area electrodes result in extremely large capacitance. Single cell voltage of ECs is typically limited to 1-3 V depending on the electrolyte used. Small electrochemical capacitors for low-voltage electronic applications have been commercially available for many years. Different applications demanding large ECs with high voltage and improved energy and power density are under discussion. Fundamental principles, performance, characteristics, present and future applications of electrochemical capacitors are presented in this communication. (C) 2000 Elsevier Science Ltd.
