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. The positive 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 including a first 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% proof stress of 3 MPa or less. The second layer contains second carbon-based active material particles with a 10% proof stress of 5 MPa or greater.
