摘要:
According to one embodiment, a nonaqueous electrolyte battery including a negative electrode that includes a negative electrode current collector and a negative electrode mixed-materials layer is provided. The negative electrode mixed-materials layer includes a titanium-including metal oxide particle that includes a phase including a carbon material on a surface and a binder that includes an acrylic resin. The negative electrode satisfies Equation (I): α/β>6 (I) α is a peel strength (kN/m) between the negative electrode current collector and the negative electrode mixed-materials layer, and β is a cutting strength (kN/m) in the negative electrode mixed-materials layer.
