ABSTRACT:
A current collector for polymer electrolyte thin film electrochemical cells and an electrochemical generator is disclosed. The current collector comprises a polymer substrate support film having a thickness of between 1 and 15 microns; a conductive metallic layer having a thickness of less than 3 microns, coated by metal vapor deposition onto at least one surface of the polymer substrate film; and a protective metal or metal oxide layer deposited onto the conductive metallic layer, having a thickness of between 5 and 500 nanometer and being electronically conductive.
