Electrolyte design represents an effective strategy for enabling battery operation over a wide temperature range. By introducing solvents with broad liquid ranges and weak solvation abilities, researchers have developed electrolytes characterized by anion‐rich solvation structures. This design not only reduces the desolvation barrier of lithium ions but also facilitates the formation of inorganic‐dominated interphases on both the cathode and anode surfaces, thereby accelerating ionic transport kinetics and suppressing side reactions. Consequently, stable electrochemical performance can be achieved across a broad temperature window. Further details can be found in the article by Han et al . on pages 453—461. image
