Problems solved by technology

[0006] However, if the structure of the secondary battery is such that the outer parts are covered only with a sheet having rubber elasticity, an excessive load may act on the secondary battery due to shock or vibration generated when the vehicle is running.

Abstract

A battery unit (1) in which a battery case (3) of a bipolar type battery (2) is constructed of an elastic member is provided. The battery unit (1) includes a reinforcement member (4) that is internally integrated within the battery case (3) to heighten the mechanical strength of the battery case (3).

Description

technical field [0001] The present invention relates to a power storage device in which an outer member of the power storage body is constituted by an elastic member. Background technique [0002] Ordinary batteries differ in external parts, including batteries whose external parts are made of metal sheets (sheets), batteries whose external parts are made of plastic sheets, and those whose external parts are made of plastic sheets provided with a metal film that prevents gas permeation battery, etc. Metal materials have good strength, but do not have good recovery (recovery) performance from deformation of a battery that generates heat during charging or discharging, so if the cycle of deformation and recovery (recovery) is repeated Excessive load will occur. This problem also exists in the case where a plastic material is used as the outer material. [0003] Therefore, in connection with the technology disclosed in Japanese Patent Application Publication No. 06-267515 (J...
