Abstract

Official abstract text for this publication.

A power storage module includes: a stacked electrode assembly which includes a plurality of electrodes stacked in a first direction and is impregnated with an electrolyte solution; and a housing accommodating the stacked electrode assembly. The housing and the stacked electrode assembly extend in a second direction perpendicular to the first direction. The power storage module further includes a plate-like member extending in the second direction and disposed facing the stacked electrode assembly within the housing. The plate-like member is disposed so that a thickness direction of the plate-like member is a third direction perpendicular to the first direction and the second direction. The plate-like member has a facing surface facing the stacked electrode assembly. At least a portion of the facing surface is curved or distorted along the second direction. The facing surface being curved or distorted forms a space between the facing surface and the stacked electrode assembly.

First claim

Opening claim text (preview).

What is claimed is: 1 . A power storage module, comprising: a stacked electrode assembly which includes a plurality of electrodes stacked in a first direction and is impregnated with an electrolyte solution; and a housing accommodating the stacked electrode assembly, wherein the housing and the stacked electrode assembly extend in a second direction perpendicular to the first direction, the power storage module further includes a plate-like member extending in the second direction and disposed facing the stacked electrode assembly within the housing, wherein the plate-like member is disposed so that a thickness direction of the plate-like member is a third direction perpendicular to the first direction and the second direction, the plate-like member has a facing surface facing the stacked electrode assembly, at least a portion of the facing surface is curved or distorted along the second direction, and the facing surface being curved or distorted forms a space between the facing surface and the stacked electrode assembly. 2 . The power storage module according to claim 1 , wherein the plate-like member has a middle portion and opposing end portions in the second direction, and the middle portion is thinner than the opposing end portions. 3 . The power storage module according to claim 1 , wherein a plurality of through-holes, passing through in the third direction, are formed in the plate-like member at different locations in the second direction. 4 . The power storage module according to claim 3 , wherein among the plurality of through-holes, a first through-hole closer to the middle portion than one of the opposing end portions has a greater open area than a second through-hole closer to the one of the opposing end portions than the middle portion.
