Kind Code:
A1
Abstract:
Disclosed is an aluminum foil which can be easily produced and has low surface resistance. The aluminum foil is capable of providing a thinner positive electrode collector film that enables an electricity storage device to have a smaller size and a higher energy density. Specifically disclosed is an aluminum foil which is characterized by supporting carbonaceous particles that are scattered thereon. The aluminum foil that supports carbonaceous particles scattered thereon can be produced by electrolysis.
