A perspective on liquid salts for energy and materials

Abstract

Liquid salts comprising molten salts and ionic liquids offer important media to address both energy and materials challenges. Here we review topics presented in this Faraday Discussion volume related to improved electrowinning of metals, optimisation of processes, new electrochemical device concepts, chemistry in ionic liquids, conversion of biomass, carbon chemistry and nuclear applications. The underlying phenomenology is then reviewed and commentary given. Some future applications are then discussed, further exemplifying the high potential rewards achievable from these chemistries.

Elucidating the influence of molten salt chemistries on the synthesis and stability of perovskites oxides

“…For example, species such as superoxides and dissolved metals, which are usually nonexistent in a solid-state PTO synthesis, can be found in the MSS. 13 The overarching chemical basis of molten salt chemistry and synthesis is understood through the Lux-Flood acid base theory: 14 Base → acid + O 2− …”
