ABSTRACT
`
`The present disclosure relates to a secondary battery module including a nonaqueous
`
`electrolyte secondary battery and an elastic body. The elastic body has a compressive
`
`elastic modulus of 5 MPa to 120 MPa.
`
`Thepositive electrode includes a positive electrode
`
`collector with a thermal conductive rate of 65 W/(m:K) to 150 W/(m:K). The negative
`
`electrode includes a negative electrode active material layer includingafirst layer and a
`
`second layer sequentially formed from a side with the negative electrode collector. The
`
`first layer contains first carbon-based active material particles with a 10% proofstress of 3
`
`10
`
`MPaorless. The second layer contains second carbon-based active material particles with
`
`a 10% proofstress of 5 MPaorgreater.
