Abstract

A non-aqueous electrolyte secondary battery includes: an electrode assembly including a positive and negative electrode plate; a rectangular outer casing having an opening; a sealing plate; an electrode terminal on the sealing plate; a first current collector connected to the electrode terminal; an insulation member; a second current collector connected to the first current collector; and a tab group extending from the electrode assembly toward the side wall and connected to the second current collector. The second current collector is a flat plate including a surface parallel to the side wall. The tab group is connected to the second current collector, and is bent at a connection portion with the second current collector such that the bent tab group extends parallel to the side wall. The second current collector is positioned on the first current collector by a guide portion extending from the insulation member.
