  "textContent": "There is provided a positive electrode active material production method, a positive electrode, and a storage device. A production method of a positive electrode active material having a LiVPOF-type crystal structure and containing carbon, includes: a step of synthesizing a precursor that has VPOcontaining carbon, from a starting material in the form of vanadium pentoxide and a phosphate compound, and from a carbon material as an additive; and a step of synthesizing LiVPOF containing carbon, from the precursor and LiF. The carbon material as an additive is conductive carbon black having a specific surface area of 700 to 1500 m/g, and in the step of synthesizing the precursor, an addition amount of the conductive carbon black is less than 2 moles per mole of vanadium pentoxide.",
