Recently, XJTU Professor Shao Jinyou's research group from the School of Mechanical Engineering discovered the dependency of the mechanical properties and electrical properties of solid super-capacitor on solid electrolyte filling, providing a novel solid electrolyte filling technology, which updated the knowledge of the flexibility and electronic characteristics of solid super-capacitors. The technology is suitable to all porous electrodes, and will exert great influence on the field of solid flexible super-capacitors.
