Abstract: To improve the adhesion between a current collector and an electrode active material so as to improve long-term reliability. An electrode is formed in the following manner: an electrode active material (a negative electrode active material or a positive electrode active material) is formed over a base, a conductive film is formed over the electrode active material by a sputtering method, the base and the electrode active material are separated at the interface therebetween, and the electrode active material is made in contact with a current collector. The conductive film has a surface with projections and depressions because the conductive film is formed on the electrode active material containing particles. Accordingly, moderate adhesion can be provided between the conductive film and the current collector, with which stress at the interface between the conductive film and the current collector can be reduced while conductivity is maintained.
Abstract translation: 为了提高集电体与电极活性物质的密合性，提高长期可靠性。 以下述方式形成电极：在基底上形成电极活性物质（负极活性物质或正极活性物质），通过溅射法在电极活性物质的上方形成导电膜， 电极活性物质在它们之间的界面处分离，并且使电极活性材料与集电体接触。 由于导电膜形成在含有颗粒的电极活性物质上，所以导电膜具有具有凹凸的表面。 因此，可以在导电膜和集电体之间提供适度的粘合，由此可以减小导电膜和集电体之间的界面处的应力，同时保持导电性。
