    摘要： A rechargeable battery including a cathode and an anode each capable of inserting and extracting an electrode reaction material, and including an electrolyte, in which the anode includes an anode current collector which is formed by including a current collector body. The anode current collector is provided thereon with an active anode material layer, and a plurality of conductive particles disposed on the surface of the current collector body with the surface facing the active anode material layer. The plurality of conductive particles is formed to include spherical particles and plate-like particles. Since a tridimensional structure having irregularities is formed on the surface of the current collector body with the spherical particles and plate-like particles, anchoring effects are greatly increased. As a result, the adhesion of the active anode material layer to the anode current collector is considerably improved.

    摘要： A secondary battery capable of obtaining superior cycle characteristics and superior swollenness characteristics is provided. The secondary battery includes a cathode, an anode, and an electrolytic solution. The electrolytic solution is impregnated in a separator provided between the cathode and the anode. An anode active material layer contains a crystalline anode active material having silicon as an element. The anode active material layer has a coating section where the surface of an anode current collector is coated with the anode active material and a non-coating section where the surface of the anode current collector is not coated with the anode active material but is exposed. Thereby, the physical property of the anode active material is hardly deteriorated with age. Further, at the time of charge and discharge, the anode active material layer is hardly expanded and shrunk, and thus the anode current collector is hardly deformed.
