Asymmetric Electrolytes Design for Aqueous Multivalent Metal Ion Batteries

Abstract

Highlights The working principle of the asymmetric electrolyte and the long-term-seated contradictory issues were analyzed. The characterization methods for the interfaces of anolyte/catholyte and electrolyte/electrode were summarized for revealing the fundamental mechanism of asymmetric electrolytes. The future research directions for asymmetric electrolyte systems were proposed.
