Abstract
A negative electrode mixture layer containing CMC and a hydroxy group-modified PVP. The mass ratio of CMC is greater than that of the hydroxy group-modified PVP. The hydroxy group-modified PVP has low affinity with a solvent for a solvent-system slurry that forms an inorganic particle layer. Adhesion strength is prevented from degrading after forming the inorganic particle layer on the negative electrode mixture layer.
