ELECTRODE FOR ELECTRICAL DOUBLE-LAYER CAPACITOR AND ELECTRICAL DOUBLE-LAYER CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a novel polarized electrode which improves manufacturing efficiency, particularly in a rolling sheet process of the polarized electrode using a carbon material which has graphite-like microcrystalline carbon.;SOLUTION: The electrode is the sheet-like electrode for an electrical double layer capacitor which contains: the carbon material which has the graphite-like microcrystalline carbon; and a binder wherein the average sphericity (X-axis Y-axis aspect ratio) of the carbon material by a flow type image analysis method is 0.65 or larger.;COPYRIGHT: (C)2010,JPO&INPIT
