Abstract
In one embodiment, a nonaqueous electrolyte secondary battery includes an electrode group, a battery container, an insulation member, and a nonaqueous electrolyte solution. The electrode group includes a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode. The insulation member, which insulates the positive electrode and the negative electrode from the battery container and absorbs vibration, includes a resin and an inorganic material and has a bending elastic modulus between 600 MPa and 1,500 MPa, a specific heat between 0.25 cal/° C.·g and 0.40 cal/° C.·g, and a thermal conductivity between 0.3 W/m·K and 0.6 W/m·K.
