Abstract
An advantage of the present invention is to suppress an increase in resistance during high-rate charge and discharge and a reduction in capacity during a charge and discharge cycle. An electrical storage module of the present embodiment includes: an electrical storage device, and an elastic body that is placed with the electrical storage device and receives a load from the electrical storage device in a placement direction. The electrical storage device includes a positive electrode, a negative electrode, and a separator. The negative electrode includes a negative-electrode active material layer. The negative-electrode active material layer includes a first layer formed on the negative-electrode current collector, and a second layer that is formed on the first layer and has a higher compression modulus than the first layer. The separator has a lower compression modulus than the first layer, and the elastic body has a lower compression modulus than the separator.
