Title:
BATTERY STRUCTURE
Document Type and Number:
Japanese Patent JP2023049356
Kind Code:
A
Abstract:
To suppress heat conduction from an excessively heat generating battery to a battery next to the heat generating battery through the surfaces facing each other of the two batteries when a battery is hotter than a normal operation temperature, and also suppress reduction of the energy density.SOLUTION: A battery structure includes: a plurality of batteries arranged at intervals in the direction of arrangement; and a spacer member provided between adjacent two of the batteries, the spacer including a pair of elastic members arranged at intervals in the direction of arrangement and an intermediate layer member which is adhesive and is located between the pair of elastic members to be integrated with the elastic members by an adhesive force, the adhesive force becoming lower when the temperature is a predetermined temperature or higher. The pair of elastic members are elastically deformed so that the size of the outer shape along the arrangement direction is increased in association with reduction of the adhesive force of the intermediate layer member in a temperature environment of at least the predetermined temperature.SELECTED DRAWING: Figure 1
