CA 2350925

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.

L'invention concerne une feuille conductrice poreuse contenant au moins des fibres conductrices inorganiques et des particules conductrices inorganiques tendres qui peuvent être par exemple en graphite expansé. A la différence des feuilles conductrices poreuses conventionnelles, la matière constituant cette feuille conductrice poreuse résiste à la rupture même pendant la fabrication et l'étape consistant à l'incorporer dans une pile, et ne se détache pas, ce qui permet de réduire les coûts de production.
