摘要： A non-aqueous electrolyte secondary battery comprises a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive electrode comprises a positive electrode mixture and a current collector, wherein the positive electrode mixture has a positive electrode active material, a binder, and a conducting agent. A lithium-containing compound having an olivine structure is used as the positive electrode active material. A copolymer of polyvinylidene fluoride, tetrafluoroethylene, and hexafluoropropylene is used as the binder. Conducting carbon powder may be used as the conducting agent. Lithium metal may be used as the negative electrode. A non-aqueous solvent in which an electrolytic salt is dissolved may be used as the non-aqueous electrolyte.
