Embodiment Construction

[0038] The power storage device of the present invention has:

[0039] a plurality of storage elements having external terminals and discharging in a first direction; and

[0040] a separator disposed between adjacent power storage elements,

[0041] external terminals of the plurality of storage elements are aligned in the first direction,

[0042] The spacer has a first end on the external terminal side and a second end opposite to the first end in a second direction perpendicular to the first direction,

[0043] A rigidity in the first direction of a portion of the spacer on the second end side is lower than a rigidity in the first direction of a portion of the spacer on the first end side.

[0044] In the power storage device configured as described above, the spacer is disposed between adjacent power storage elements. Therefore, in a normal state, a plurality of power storage elements are arranged at intervals in the first direction. It should be noted that the normal...

Abstract

The present invention aims to provide an electric storage apparatus configured to prevent external terminals of adjacent electric storage devices from contacting each other, even if a compressive force in a direction in which a plurality of electric storage devices are aligned acts thereon. In the electric storage apparatus of the present invention, a spacer is arranged between each adjacent two of the plurality of electric storage devices having external terminals, and a portion opposite to the external terminal side of the spacer has a lower rigidity than a portion on the external terminal side of the spacer.

Description

technical field [0001] The present invention relates to an electrical storage device including a plurality of electrical storage elements. Background technique [0002] Conventionally, power storage devices have been provided as power sources for various devices. The power storage device includes: a plurality of power storage elements that have external terminals and are discharged in a first direction, a spacer disposed between adjacent power storage elements, and holding the plurality of power storage elements and the spacer. frame of things. [0003] The frame includes a pair of terminal members disposed on both sides of the plurality of power storage elements in the first direction and sandwiching the plurality of power storage elements, and a connecting member (for example, Patent Document 1). [0004] However, in the power storage device as described above, by arranging the power storage elements at equal intervals, the air permeability between the separator and the...
