The project’s main goal will be to develop high-performance Na-ion HSCs based on the local abundant biomass materials to lower the cost over current technologies, complementing or even replacing the existing costly stationary energy storage system.
The sub-goals are to:
Develop the process to derive activated carbon (specific surface area > 2500 m2/g, specific capacitance > 150 F/g in organic electrolyte) and hard carbon (interlayer spacing d002 > 0.4 nm, specific capacity > 300 mAh/g) from biomass.
Produce Na-ions energy storage device made of biomass-derived carbon materials with an energy density above 50 Wh/kg and a life cycle above 30,000
Develop a Na-based household energy storage system prototype with a capacity of 10 Wh at half price compared to the existing commercial energy storage system
