US Patent 9246150 Non-aqueous electrolyte battery

A non-aqueous electrolyte battery in which formation of a flame retardant layer formed on the surface of an electrode or the like hardly affects the discharge characteristics is provided. A non-aqueous electrolyte battery 1 includes a positive electrode 3, a negative electrode 5, and a separator 7. A porous layer having ion permeability is formed using a flame retardant material on a surface of the positive electrode 3. The porous layer is formed by applying a hot melt, which is a fused flame retardant material made of a thermoplastic resin, to the surface of the positive electrode 3.
