2023 – 2026 Elucidation of the aqueous ELEctrochemical deGRAdation and aging processes in NASICON-Type materials: towards in situ NMR (ELEGRANT), funded by Research Council of Lithuania, P-MIP-23-146. PI- dr. Vytautas Klimavičius
The current shift towards more sustainable energy and materials systems requires significant development in energy conversion and storage technologies based on non-critical materials. Alternative technologies, such as aqueous Na-ion batteries could solve many of the mentioned issues due to their safety, cost and sustainability at the expense of reduced energy density which is less important for stationary power grid stabilisation applications. Project ELEGRANT aims to contribute to the field of sustainable energy conversion. This will be achieved by developing NASICON-structured (Na Super Ionic CONductor) materials for the electrochemical applications. For the successful application of NASICON based materials in technologies such as battery electrode materials, separators for redox flow and seawater batteries, or as insertion hosts for capacitive deionization cells, the understanding of the relation between molecular structure and macroscopic properties is an essential factor. In order to elucidate structure - properties relations, experimental investigations using various techniques are required. Solid-state NMR among other methods has a handful of experimental techniques allowing to reveal fine details on studied materials. It provides information on the molecular level and allows to detect all crystalline and amorphous species in the studied systems which is often an issue for other techniques. Among development of NASICON-based materials for electrochemical applications, project ELEGRANT aims to perform extensive solid state NMR based investigation on these materials which include ex-situ and in-situ approaches employing MAS, MQMAS, REDOR-type, wideline methods. The obtained data will contribute for the application of NASICON-based materials in battery technology as well as the development of solid state NMR methodology for studying such type of functional materials.
