ALUMINUM FOIL WHICH SUPPORTS CARBONACEOUS PARTICLES SCATTERED THEREON

摘要

An object of the present invention is to provide an aluminum foil that can make a positive electrode current collector thinner for size reduction and higher energy density of electrical storage devices, be produced easily and has a low surface resistance. An aluminum foil of the present invention as a means for achieving the object is characterized in that carbonaceous particles are dispersed and supported therein. The aluminum foil with carbonaceous particles dispersed and supported therein of the present invention can be produced by electrolysis.
