`
`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
`
`um to 8 um. The negative electrode includes a first layer and a second layer sequentially
`
`formed from a side with the negative electrode collector.
`
`Thefirst layer contains negative
`
`10
`
`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 MPaor greater.
