Abstract
A battery can include an electrode assembly having a first electrode, a second electrode and a separator. The first electrode can include a first active material region coated with an active material layer along a winding direction and a first uncoated region not coated with the active material layer, and at least part of the first uncoated region used as an electrode tab. The battery can further include a first current collector coupled to at least part of the first uncoated region on the electrode assembly, a battery housing to accommodate the electrode assembly and the first current collector, and an insulator between an inner surface of the battery housing facing the first uncoated region or the first current collector and the first uncoated region or the first current collector to block the electrical connection between the first uncoated region and the battery housing.
