Problems solved by technology

However, when the insulating film is heat-sealed, the insulating film may shrink and form a hard block
If other components are designed so as to avoid interference with the block, the degree of freedom of design decreases, and as a result, the miniaturization of the entire module including the electric storage unit may be hindered.

Abstract

The present disclosure provides a power storage cell capable of achieving insulation protection and improving the degree of freedom of design of peripheral members, and a method for manufacturing the same. A power storage unit (100) is provided with: an outer tank (120) having a top surface (120D), a bottom surface (120C), and side surfaces (120B) positioned between the top surface (120D) and the bottom surface (120C); and an insulating film (130) that covers at least a side surface (120B) of the outer can (120). The insulating film (130) has a seam (130a) on a side surface (120B) of the outer can (120), and the seam (130a) on the side surface (120B) is heat-sealed. The heat seal section (140) on the side surface has a terminal section (140A) at a position separated from the top surface (120D) or the bottom surface (120C) of the outer can (120).

Description

technical field [0001] The present disclosure relates to an electric storage unit and a method of manufacturing the same. Background technique [0002] From the viewpoint of realizing electrical insulation protection, the housing of the electric storage unit has conventionally been covered with an insulating film. As a conventional structure, the structure described in Unexamined-Japanese-Patent No. 2013-33668 (patent document 1) is mentioned, for example. [0003] When the housing is covered with an insulating film, a seam may be formed on the insulating film. By heat-sealing the seam, the seam can be closed to achieve insulation protection. However, when the insulating film is heat-sealed, the insulating film may shrink to cause hard lumps. If it is desired to design other components so as to avoid interference with the block, the degree of freedom in design decreases, and as a result, the miniaturization of the entire module including the electric storage unit may be h...
