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 nonaqueous electrolyte secondary battery includes a positive electrode and a negative electrode. The positive electrode includes a positive electrode collector containing Ti as a main component and having a thickness of 1 μm to 8 μm. The negative electrode includes a first layer and a second layer sequentially formed from a side with the negative electrode collector. The first layer contains negative electrode active material particles containing first carbon-based active material particles with a 10% proof stress of 3 MPa or less. The second layer contains negative electrode active material particles containing second carbon-based active material particles with a 10% proof stress of 5 MPa or greater.
