Abstract
An anode, an anode current collector, an anode active material and a battery using the anode are provided. The anode includes the anode current collector and the anode active material. The anode current collector has a projection. The anode active material layer is formed via at least one of a vapor deposition method, a liquid-phase deposition method, a sintering method and the like.
Claims19
An anode, comprising:
- an anode current collector comprising a projection provided on a substrate, the substrate having an arithmetic mean roughness Ra of 0.05 μm to 0.2 μm;
- and
- an anode active material layer disposed on the anode current collector and the projection,
- wherein the anode active material layer is alloyed with the anode current collector in at least a portion of an interface with the anode current collector, and
- wherein the anode active material layer includes at least one kind selected from the group consisting of silicon and silicon compounds.
