Abstract: 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.

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.

Abstract: A non-aqueous electrolyte battery providing high safety and having stable battery characteristics in which a flame retardant has little effect on the battery characteristics when the battery is in a use environment and in which flame retardance is imparted to a non-aqueous electrolyte when the battery generates an abnormal amount of heat is provided. The battery includes a non-aqueous electrolyte and a large number of flame retardant particles added to the electrolyte as the flame retardant is formed. The particles are made of a material that exists as a solid and does not perform a function of suppressing ignition when the temperature of the electrolyte is equal to or less than a reference temperature at which the electrolyte is likely to start combustion and that is at least partially liquefied and performs a function of suppressing combustion when the temperature of the non-aqueous electrolyte is more than the reference temperature.
