Abstract
A battery having high output voltage, high energy density and excellent charge and discharge cycle characteristics is achieved through the use of one of the following negative electrode base members as a negative electrode base member for lithium ion secondary batteries: a negative electrode base member where a metal film is formed on a support having an organic film; such a negative electrode base member where the surface layer of the organic film is covered with a metal oxide film; a negative electrode base member where a metal film is formed on a support having a composite film formed from a composite film-forming material containing an organic component and an inorganic component; and a negative electrode base member where a silica coating is formed, on a support having a photoresist pattern, from a silica film-forming coating liquid and a metal film is formed on the support after removing the photoresist pattern.
