摘要

PROBLEM TO BE SOLVED: To provide: a polyacetylene derivative for a nonaqueous secondary battery positive electrode active material having excellent cycling characteristics; a positive electrode active material; a positive electrode; a nonaqueous secondary battery; and a vehicle equipped with the nonaqueous secondary battery.SOLUTION: The polyacetylene derivative has an anthraquinonediimine substituent. The positive electrode active material is a positive electrode active material for a nonaqueous secondary battery comprising the polyacetylene derivative. The positive electrode is a positive electrode for a nonaqueous secondary battery provided with the positive electrode active material. The nonaqueous secondary battery includes the positive electrode, a negative electrode and an electrolyte. The vehicle is equipped with the nonaqueous secondary battery.
