ABSTRACT:
A battery using the anode, and methods of manufacturing the anode and the battery are provided. The battery is capable of relaxing stress while securing the contact characteristics between an anode current collector and an anode active material layer, and capable of improving the characteristics. The anode active material layer containing Si as an element is provided on the anode current collector. The anode active material layer includes a first anode active material layer having a first particle formed by being grown on the anode current collector by vapor-phase deposition method and a second anode active material layer having a second particle with an average particle diameter ranging from 0.2 μm to 20 μm which is deposited on the first anode active material layer by coating the first anode active material layer with the second particles.
