Opis projektu
Wykorzystanie najnowszych innowacji w zakresie magazynowania energii
Rosnące zapotrzebowanie na tanie, skalowalne i ekologiczne koncepcje magazynowania energii doprowadziło do powstania szeregu innowacyjnych rozwiązań, materiałów i technologii charakteryzujących się doskonałymi osiągami. Na ich liście znajdziemy między innymi zwiększanie bezpieczeństwa i sprawności akumulatorów sodowych, zwiększanie wydajności nanoporowatych elektrod węglowych, wykorzystywanie materiałów hybrydowych oraz zmian struktury elektrochemicznej w celu uzyskania lepszych osiągów. Zespół finansowanego ze środków Unii Europejskiej projektu MoMa-STOR zamierza ocenić te nowatorskie technologie magazynowania energii i zbudować stosowną bazę materiałową w celu opracowania urządzeń do magazynowania energii następnej generacji.
Cel
Sustainable energy generation by water, wind, and solar has reached in the EU a mature and economic state, but further growth to tackle the climate crisis has faltered because more economic, scalable and sustainable energy storage concepts are missing.
The groups of both PIs have a proven track record in this area but, interestingly they were able just recently to perform first experiments indicating big potential gains in performance. The Simon group identified a specific ion organization in nanoporous carbon electrodes leading to enhanced capacity. He also evidenced fast, new pseudocapacitive redox contribution in metal carbides of still unclear origin. The Antonietti group could not only build from oxidation stable noble carbons a 6.5 Volt supercapacitor, but also show that in those new device major storage peaks come from solvent structure changes. In another work, massive sub-potential deposition of Na-metal was observed is the Schottky transition layers of hybrid materials, thus making sodium batteries potentially save and efficient.
The general aim of MoMa-STOR is to address such fundamentally new, non-classical and non-technically covered modes of energy storage and to develop the related materials base for them, to design the next generation of energy storage devices.
These new modes include a) energy storage by desolvation and matrix change, b) reversible high energy bulk structure transition, and c) metal-metal and metal-semiconductor heterojunction interface effects.
New modes will be carefully analysed with advanced electrochemical techniques, including quartz crystal microbalance, differential electrochemical mass spectroscopy, combined with in situ X-ray and Raman spectroscopy for instance, to gain a precise physico-chemical picture of the operation principles. In operando high resolution electron microscopy and EELS will complete the molecular understanding of the processes.
