COLLECTOR, ELECTRODE SHEET, AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a positive electrode sheet (10) (electrode sheet), which is provided with an aluminum foil (12) that serves as a collector substrate, a titanium film (32) that is formed on the surface of the aluminum foil (12), and a binder-less carbon film (34) that is formed on the surface of the titanium film (32). An active material layer (20) is formed on the binder-less carbon film (34). In the positive electrode sheet (10), the binder-less carbon film (34) is not easily separated, and the active material layer (20) is not easily separated.
