摘要： An anode in which an anode active material layer is arranged on an anode current collector. The anode active material layer includes anode active material particles made of an anode active material including at least one of silicon and tin as an element. An oxide-containing film including an oxide of at least one kind selected from the group consisting of silicon, germanium and tin is formed in a region in contact with an electrolytic solution of the surface of each anode active material particle by a liquid-phase method such as a liquid-phase deposition method. The region in contact with the electrolytic solution of the surface of each anode active material particle is covered with the oxide-containing film, to thereby improve the chemical stability of the anode and the charge-discharge efficiency. The thickness of the oxide-containing film is preferably within a range from 0.1 nm to 500 nm both inclusive.

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： The present invention uses a mixture of spherical carbonaceous materials having different average particle sizes as an anode active material in an anode composite mixture layer of an anode. The spherical carbonaceous material of large particle size decreases the reaction with non-aqueous electrolyte solution to suppress the decrease in battery capacity, form clearances having suitable sizes in the anode composite mixture layer, and retain the non-aqueous electrolyte solution. The clearances in the anode composite mixture layer are efficiently filled with the carbonaceous material of small particle size while spaces capable of suitably retaining the non-aqueous electrolyte solution are left unfilled. Thus, the volume density of the anode composite mixture layer is improved and the battery capacity is increased. Accordingly, energy density can be increased without deteriorating battery characteristics.
