  "textContent": "A non-aqueous electrolyte battery capable of flattening of a voltage property and securing safety at a time of battery abnormality is provided. A lithium-ion secondary battery 20 has an electrode group 6 in which a positive and a negative electrode plates are wound. A non-aqueous electrolyte is formed by adding LiBF 4 to a mixed solvent of EC and DMC. In the positive electrode plate, a positive electrode mixture layer W2 including a positive electrode active material is formed at both surfaces of an aluminum foil W1. A lithium manganese magnesium complex oxide having a spinel crystal structure is used as the positive electrode active material. A flame retardant layer W6 including a phosphazene compound is formed at a surface of the positive electrode mixture layer W2. In the negative electrode plate, a negative electrode mixture layer W4 including a negative electrode active material is formed at both surfaces of a rolled copper foil W3. A carbon material that a surface of graphite is coated by pyrolytic carbon is used as the negative electrode active material. The phosphazene compound demonstrates non-flammability, and a voltage property is flattened by the graphite material.",
