Electrochemical energy storage materials, devices, and hybrid systems


The electrochemical capacitor (EC) is an important energy storage technology for high power and fast energy deliveries. Our research in EC covers chemical modifications and characterizations of electrode materials (nanocarbon and transition metals), investigation of solid polymer electrolytes, and development and characterization of symmetric and asymmetric cells and hybrid systems. In terms of electrodes, we are focusing on chemical modifications of porous and nonporous carbon materials to add pseudocapacitance for enhanced energy density and conductivity. As for electrolytes, we are investigating polymer proton conducting electrolytes for ECs which can greatly improve the volume energy and power density with very thin form factors. The thin cells are combined with batteries or solar cells to form hybrid energy devices for prolonged fast energy delivery and for self-powered energy devices.
