Na metal / NaSICON All-Solid-State Batteries: towards impoved safety, sustainability, energy and power density in batteries

Lead Research Organisation: Imperial College London
Department Name: Materials

Abstract

Na metal all-solid-state batteries have the potential to address three crucial objectives for the development of next-generation batteries: an improved safety due to the absence of flammable liquid electrolytes; the presence of more earth abundant elements in its composition than conventional Li-ion batteries; a dramatic boost in energy density originating from the use of high capacity Na metal anodes and high voltage cathodes.

With this project, we aim at understanding the fundamental limitations of the anode/solid-electrolyte interface and how to overcome them. Focusing on the highly ionically conductive family of NaSICON Na conducting solid-electrolytes, this project shines light on methods to reduce the high Na metal / NaSICON interfacial resistance. It will also provide information about the degradation of this interface with time and the formation of a so-called Solid Electrolyte Interface (SEI).
