[Two departments: Research large-capacity high-specific power battery energy storage and promote pilot applications of high-specific power battery energy storage and supercapacitors] On November 13, the National Development and Reform Commission and the National Energy Administration issued the "New Energy Storage Implementation Plan for the 15th Five-Year Plan". Develop short-term high-frequency power energy storage technology. Develop low-cost and high-strength materials for flywheel energy storage, high-performance bearings, vacuum high-speed motors, etc., and optimize rotor heat dissipation technology; research high-performance materials and devices for supercapacitors, study large-capacity high-specific power battery energy storage, promote high-specific power battery energy storage, and pilot applications of supercapacitors; develop high-temperature superconducting materials.
