摘要:
According to one embodiment, a non-aqueous electrolyte battery includes an electrode group. The electrode group includes a positive electrode and a negative electrode. At least one of the positive electrode or the negative electrode has a first electrode part and a second electrode part. The first electrode part includes a first metal substrate and an active material-containing part. The second electrode part includes a second metal substrate and an active material-containing part. The first metal substrate has a tensile strength larger than a tensile strength of the second metal substrate. A part of the first electrode part is provided more outside of the electrode group than a part of the second electrode group.
