Abstract
A non-aqueous electrolyte battery capable of securing safety at a time of battery abnormality and restricting a drop in a charge/discharge property or lowering in an energy density at a time of battery use is provided. The lithium-ion secondary battery 1 has an electrode group 5 formed by winding a positive electrode plate 2 that a positive electrode mixture layer including an active material is formed at a collector, a negative electrode plate 3 that a negative electrode mixture layer including an active material is formed at a collector via a porous separator 4. A flame retardant layer is disposed at one side or both sides of at least one kind of the positive electrode plate, the negative electrode plate and the separator. The flame retardant layer contains a non-fluorinated organic polymer, a flame retardant and a thickener.
