Search, characterisation and application of novel materials for aųueous Na-ion energy storage systems

Electrochemical batteries represent one of the most attractive choices for electrical energy storage since they cover the widest range of power and energy, have superior round-trip energy efficiency, low environmental footprint, and easy scalability. Aqueous Na-ion batteries represent an attractive alternative to traditional non-aqueous Li-ion batteries, since they are based on abundant materials safe, non-flammable, low-cost and environmentally friendly. However, the narrow electrochemical stability window of water imposes a significant limit on the available energy densities of such systems and restricts their applicability to the field of stationary storage. The main tasks of this project are the search, synthesis, structural and electrochemical characterization of novel battery materials based on NASICON phosphate frameworks and their application for novel battery cells.

Synthesis, characterization and applications of novel materials for aqueous Na-ion batteries is a new research direction within the Department Electrochemical Materials Science. All the new activities are started and developed within the Lithuanian Research Council Grant NaAquaCell (2018-2022). A young team of experienced chemists, electrochemists and physicists has been assembled which is engaged in materials preparation, characterization and electrochemical testing. We operate well stocked solid-state chemistry (furnaces for ceramic synthesis) and electrochemistry (Zahner Zennium, Metrohm Autolab 302 electrochemical workstations, Neware 24 channel battery cycler etc.) labs.
