POROUS CONDUCTIVE SHEET AND METHOD FOR PRODUCING THE SAME

摘要

A porous conductive sheet containing at least inorganic conductive fibers and soft inorganic conductive particles which are made of expanded graphite in one aspect of the invention. Unlike conventional porous conductive sheets, the member constituting the porous conductive sheet of the invention is immune from breakage even in the steps of forming the sheet and incorporating the sheet in a cell and from coming off, thereby lowering the production cost.
