    摘要： A negative electrode for a rechargeable lithium battery which is obtained by sintering under a non-oxidizing atmosphere, in the form of a layer on a surface of a metal foil current collector, an anode mix containing a binder and particles of active material containing silicon and/or a silicon alloy; the negative electrode being characterized in that the metal foil current corrector has projections and recesses on its surface, the projection is shaped to have a recurved side face portion that curves more outwardly as it extends closer to a distal end of the projection, and the binder penetrates into spaces defined by the recurved side face portions.

    摘要： A method of manufacturing an electrode for a secondary battery by depositing a thin film composed of active material on a current collector in which a surface-treated layer such as an antirust-treated layer is formed, including the steps of: removing at least part of the surface-treated layer by etching the surface of the current collector with an ion beam or plasma in order to improve the diffusion of the current collector material into the active material thin film; and depositing the thin film on the surface of the current collector subjected to the etching step.

    摘要： A method of manufacturing an electrode for a secondary cell capable of readily forming an active material layer only on a necessary portion of a collector by a method supplying raw material from a gas phase is obtained. This method of manufacturing an electrode for a secondary cell comprises steps of forming a mask layer containing a material reduced in adhesion to a collector due to a high temperature for forming an active material layer on a prescribed region of the collector, forming the active material layer on the collector and on the mask layer by a method supplying raw material from a gas phase and removing the mask layer and part of the active material layer formed on the mask layer. Thus, the mask layer is readily separated from the collector after the active material layer is formed by the method supplying raw material from a gas phase. Consequently, the mask layer and part of the active material layer formed on the mask layer are so readily removed that the active material layer is readily located only on a necessary portion of the collector.
