Monovalent manganese based anodes and co-solvent electrolyte for stable low-cost high-rate sodium-ion batteries

Abstract

Sodium ion batteries offer more cost-effective storage than lithium and could be used for grid-scale energy storage. Here, the authors demonstrate a full cell based on a MnHCMn anode and an organic-aqueous cosolvent electrolyte. X-ray spectroscopy evidence further suggests the presence of Mn(I).
