1. A battery, comprising:
an electrode assembly including a first electrode, a second electrode and a separator interposed between the first electrode and the second electrode wound around a winding axis, defining a core and an outer circumferential surface, wherein the first electrode includes 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 itself is used as an electrode tab;
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;
an insulator interposed 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: and
a terminal electrically connected to the first uncoated region, wherein at least part of the terminal is exposed through a through-hole on top of the battery housing,
wherein the insulator includes:
a first cover portion which covers an end of the first uncoated region or a surface of the first current collector facing the inner surface of the battery housing,
wherein the insulator has a center hole having a predetermined diameter at a center of the first cover portion, and
wherein the terminal includes:
a body portion inserted into the through-hole;
an outer flange portion extended from one side periphery of the body portion exposed through a top outer surface of the battery housing along the outer surface;
an inner flange portion extended from an opposite side periphery of the body portion exposed through a top inner surface of the batter housing toward the inner surface; and
a welding portion provided inside the inner flange portion.
