Novel energy storage concepts and devices

Author: Krzysztof Fic

Abstract:

The goal of the project was to develop a supercapacitor with high specific power (up to 5 kW/kg) and energy (up to 20 Wh/kg) preserved along at least 50 000 cycles. The project resulted in remarkable enhancement of specific energy, power and lifespan. Advanced electrochemical testing was accompanied by materials design. Moreover, implementation of novel concepts of the electrolytes and designing of new operando technique for capacitor characterization was made, resulting in sustainable and efficient energy conversion and storage system.
