SECONDARY-BATTERY CURRENT COLLECTOR FOIL AND METHOD OF MANUFACTURING THE SAME

摘要

A secondary-battery current collector foil (X) includes: an electrically conductive metal foil element (1); a metal intermediate layer (2) formed on the metal foil element (1); and a carbon thin film layer (3) deposited on the metal intermediate layer (2). The metal intermediate layer (2) is formed between the metal foil element (1) and the carbon thin film layer (3) so that the metal intermediate layer (2) closely adheres to both the metal foil element (1) and the carbon thin film layer (3).
