Electrochemical Energy Conversion and Storage Laboratory (EECS Lab) is a part of nESSI group at IMPEE Heriot-Watt University. Our research topics are dedicated to the electrochemical energy storage and conversion system and device design including solar-rechargeable redox flow battery (SRFB), RFB with thermally-regenerative electrochemical cycle (TREC), and photo- and electro-chemical (PEC & EC) device architecture. Currently, our research is focused on both theoretical modelling and experimental verification that reveal untapped potential of the electrochemical energy conversion and storage systems.
