A positive electrode active material for a non-aqueous electrolyte secondary battery, comprising LiX, where X represents a halogen atom.
A method of manufacturing a positive electrode active material for a non-aqueous electrolyte secondary battery, the method comprising a step of blending LiX with another substance, where X represents a halogen atom.
A method of charging and discharging a battery including a positive electrode and a negative electrode, the method comprising:
- a charge step including causing LiX, where X represents a halogen atom, to ionize to generate Li+, X−, and an electron in the positive electrode, and causing the electron to migrate to the negative electrode;
- and
- a discharge step including causing the Li− and the X− to bind to each other to generate LiX in the positive electrode, and causing an electron to migrate from the negative electrode to the positive electrode.
