  • ELECTRODE AND BATTERY
    Publication number: 20080138716
    Abstract: A battery realizing the superior cycle characteristics is provided. An electrode includes a current collector including an active-material-layer-formation region and a flat and smooth region having a surface roughness smaller than that of the active-material-layer-formation region, and an active material layer provided in the active-material-layer-formation region of the current collector. An electrode lead is connected to the flat and smooth region.
