This review mainly summarizes the recent progress in addressing the challenges of sodium metal batteries through electrolyte optimization. It discusses the advancements in liquid electrolytes and solid-state electrolytes, as well as their applications in improving the electrochemical performance of sodium metal anodes. The review emphasizes the critical challenges and new perspectives in electrolyte engineering for high-performance sodium metal batteries.
Intermittent renewable energy requires a powerful energy storage system to smoothen the relationship between power generation and power consumption. Due to the rapidly rising price of Li resources, the development of Li-ion batteries (LIBs) has been severely limited. Therefore, developing high-efficiency and low-cost Na-ion batteries has become an alternative to energy storage systems. The high potential plateau of most anode materials urges the exploration of the ultimate anode, the Na metal anode. However, three big dilemmas regarding Na metal anodes, including the formation of Na dendrites, the formation of dead Na, and the continuous appearance of bare Na lead to the degradation of the performance of Na metal batteries (NMBs). In this review, we mainly summarize the recent progress to address these dilemmas for NMBs by electrolyte optimization. We firstly discuss the liquid electrolyte progresses to improve the Na metal anode's electrochemical performance by solvent chemistry, salt chemistry, and additive. In addition, considering the ultimate goal of NMBs is solid-state batteries, we also discuss the recent progress of polymer electrolytes and all-solid-state electrolytes for Na metal anodes and summarize the enhancement of Na-ion transport mechanisms and interface engineering mechanisms of different solid-state electrolytes. Furthermore, the critical challenges and new perspectives of NMBs using electrolyte optimization are also emphasized. We believe that our review will provide insight to conduct more comprehensive and effective electrolyte engineering for high-performance NMBs.
