Battery, current collector plate applied thereto, and battery pack and vehicle comprising the same

A battery, comprising:

• an electrode assembly including a first electrode and a second electrode and a separator interposed therebetween wound together around a winding axis to define a core and an outer circumferential surface, wherein the first electrode and the second electrode have a first electrode tab formed of a first uncoated portion and a second electrode tab formed of a second uncoated portion at a long side end along a winding direction, respectively, and wherein the first electrode tab and the second electrode tab protrude outside of the separator in opposite directions along a winding axis direction;
• a battery housing accommodating the electrode assembly, and electrically connected to the second electrode tab;
• a terminal installed to be insulated from the battery housing and exposed outside of the battery housing;
• and
• a current collector plate disposed between the first electrode tab and the terminal for electrical connecting thereof, the current collector plate including:
• an edge portion which defines a space inside;
• a tab coupling portion extended from the edge portion in a centripetal direction and coupled to the first electrode tab;
• a terminal coupling portion disposed radially inward of the edge portion;
• and
• a connection portion connecting the terminal coupling portion to the edge portion,
• wherein the first electrode tab is coupled to the tab coupling portion of the current collector plate, and the terminal is coupled to the terminal coupling portion of the current collector plate.
