Separator, battery module and battery module production method

Abstract

A separator includes an intervening portion that is disposed between two adjacent batteries and insulates the two batteries, an input part that receives external force input during assembly of a battery module and is deformable by the external force, and a battery pressing part that is in contact with a first surface of one of batteries, the first surface extending in a stack direction X of the batteries, and use the external force input into the input part to press the first surface.

1 . A plurality of separators used in a battery module that includes a plurality of batteries stacked, each the plurality of separator comprising:
 an intervening portion that is disposed between two adjacent batteries of the plurality of batteries and insulates the two adjacent batteries;   an input part that receives external force input during assembly of the battery module and that is deformable by the external force; and   a battery pressing part that is in contact with a first surface of one of the two adjacent batteries, the first surface extending in a stack direction of the plurality of batteries, and uses the external force input into the input part to press the first surface; and   a heat dissipater that is in contact with a second surface of each of the plurality of batteries that is opposite the first surface of the battery that is pressed by the battery pressing part of corresponding one of the separators and dissipates heat of the plurality of batteries.   
     
     
         2 . The battery module according to  claim 1 ,
 wherein each of the plurality of separators does not regulate displacement of adjacent separators of the plurality of separators.
