Abstract
According to one embodiment, an electrode composite is provided. The electrode composite includes a negative electrode active material-containing layer and an insulating particle layer. The negative electrode active material-containing layer includes negative electrode active material secondary particles having an average secondary particle size of from 1 μm to 30 μm. The insulating particle layer is provided on the negative electrode active material-containing layer. The insulating particle layer includes a first surface and a second surface opposed to the first surface. The first surface is in contact with the negative electrode active material-containing layer. The second surface has a surface roughness of 0.1 μm or less.
