Abstract:
[Problem] To provide a rectangular nonaqueous electrolyte secondary battery for which the generation of a magnetic field due to current during use is suppressed and the danger of internal shorts between the positive electrode tab and negative electrode tab is reduced. [Solution] The positive electrode tab and negative electrode tab are both disposed at the beginning side of a winding for wound electrodes. An outer housing and sealing plate are welded in a state with the positive electrode tab sandwiched at a mating part of the outer housing and sealing plate. The negative electrode tab is electrically connected to a negative electrode terminal provided on the sealing plate. The positive electrode tab and negative electrode tab are divided by a space of 2-12 mm in the direction of battery width.
