Perspective on Lewis Acid‐Base Interactions in Emerging Batteries

Abstract

AbstractLewis acid‐base interactions are common in chemical processes presented in diverse applications, such as synthesis, catalysis, batteries, semiconductors, and solar cells. The Lewis acid‐base interactions allow precise tuning of material properties from the molecular level to more aggregated and organized structures. This review will focus on the origin, development, and prospects of applying Lewis acid‐base interactions for the materials design and mechanism understanding in the advancement of battery materials and chemistries. The covered topics relate to aqueous batteries, lithium‐ion batteries, solid‐state batteries, alkali metal‐sulfur batteries, and alkali metal‐oxygen batteries. In this review, the Lewis acid‐base theories will be first introduced. Thereafter the application strategies for Lewis acid‐base interactions in solid‐state and liquid‐based batteries will be introduced from the aspects of liquid electrolyte, solid polymer electrolyte, metal anodes, and high‐capacity cathodes. The underlying mechanism is highlighted in regard to ion transport, electrochemical stability, mechanical property, reaction kinetics, dendrite growth, corrosion, and so on. Last but not least, perspectives on the future directions related to Lewis acid‐base interactions for next‐generation batteries are like to be shared.
