eNargiZinc aims at developing new knowledge, technology, and commercially exploitable products related to innovative and affordable next-generation of electrochemical energy storage devices. The project encompasses comprehensive research on all the essential parts needed to develop sodium-ion batteries (SIBs), zinc-air batteries (ZABs), and zinc-ion batteries/hybrid supercapacitors (ZIBs/ZHSCs). This includes the exploration of sustainable electrode materials, electrolytes, and, specially, the integration of all the developed components into full cells at an industrially-relevant scale.
