Problems solved by technology

Therefore, in the case of all-solid-state battery expansion, there is a possibility of excessively high confinement pressure
Since excessive confinement pressure will load both the all-solid-state battery and the confinement member, it is possible to degrade at least one of them, degrading the performance of the battery
In addition, in the case of shrinkage of the all-solid-state battery, it may not be possible to apply sufficient confinement pressure

Embodiment Construction

[0038] Hereinafter, the present invention will be described through embodiments of the invention, but the inventions in the scope of claims are not limited to the following embodiments. In addition, in order to clarify description, the following description and drawing are simplified suitably.

[0039] In addition, in the present invention, "curing" includes the case where the resin is cured by chemical reaction between the resin and the resin and the crosslinking agent, and the case where the resin is cured by cooling to below the glass transition temperature without chemical reaction. Condition.

[0040] First, the case structure of the present embodiment will be described. figure 1 It is a perspective view which schematically shows the case of this embodiment. In addition, in the following description, the three-dimensional (XYZ) coordinate system is used for description in order to clarify description. In addition, the scales in the respective axial directions may diffe...

Abstract

A case having elasticity corresponding to expansion and contraction of a stacked body housed therein and a method for manufacturing the same, a method for inserting the stacked body into the case, anda cell stack using the case are provided. A case configured to house a stacked body includes two opposed contact parts in contact with the stacked body, and two spring structures connecting the two contact parts with each other.

Description

technical field [0001] The present invention relates to a case, a method for manufacturing the same, a method for inserting a laminate, and a battery stack. Background technique [0002] In order to make the all-solid-state battery perform a battery reaction, it is necessary to apply, for example, left and right pressure. [0003] As a constraining member that applies a constraining pressure in the stacking direction of a stack constituting an all-solid-state battery, Japanese Patent Application Laid-Open No. 2018-14286 discloses a constraining member having: a plate-like portion sandwiching both surfaces of the stack; A rod-shaped part connecting the two plate-shaped parts; and an adjusting part connected to the rod-shaped part and adjusting the restraining pressure by a screw structure or the like. [0004] Japanese Patent Application Laid-Open No. 2018-107003 discloses a method of sealing and housing an all-solid-state battery laminate in an external can. In the metho...
