摘要
集流体用穿孔箔是锂离子电容器的重要组成部分,不仅为锂离子电容器电极预掺锂提供通道,使锂离子迅速、均匀地掺杂到整个电极中,而且还承载电极活性材料,并将产生的电流汇集起来。系统地介绍了穿孔箔的主要结构参数(孔径、孔隙率)对锂离子电容器电化学性能的影响规律及其机理,并综述了锂离子电容器集流体用穿孔箔的制备方法,最后展望了穿孔箔的发展趋势。
Perforated foil of electrode collector is an important component of lithium ion capacitor, which pro vides the way for electrode active materials to predope lithium ions rapidly, and serves as carriers of electrode activa ted materials,and collect the current of electrode activated materials. A comprehensive review is presented on the methods in preparation for perforated foil and the analysis of the mechanisms responding to shapes parameters （hole diameter,opening rates） of perforated foil is done. In the end, the development trend of perforated foil are also pro posed.
