Non-aqueous batteries

Abstract

To mitigate current concentration in the vicinity of a terminal in a lateral terminal structure.SOLUTION: A non-aqueous battery includes a case, an electrode body, and an electrolyte. The case has a rectangular parallelepiped shape. The case has a width direction, a height direction, and a thickness direction. The case includes a first side wall and a second side wall. The second side wall faces the first side wall. Each of the first side wall and the second side wall is orthogonal to the width direction. A cathode terminal and an anode terminal are provided to the first side wall. The electrode body is a wound type. The winding axis of the electrode body is parallel to the width direction. The electrode body includes a first end and a second end. The first end faces the first side wall. A relationship R1 / R2>1 is satisfied. R1 denotes electrode resistance at the first end, and R2 denotes electrode resistance at the second end.SELECTED DRAWING: Figure 1
