A dimethylacetamide-based eutectic electrolyte for high-performance aqueous lithium-ion batteries

Abstract

By designing dimethylacetamide-based aqueous eutectic electrolytes, an inorganic-rich interfacial phase was achieved to regulate the electrode–electrolyte interface and suppress the hydrogen evolution reaction. A high-voltage aqueous LiMn₂O₄‖Li₄Ti₅O₁₂ battery was successfully developed and maintained stability over 870 cycles.
