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.
