Rechargeable batteries have been indispensable for various portable devices, electric vehicles, and energy storage stations. The operation of rechargeable batteries at low temperatures has been challenging due to increasing electrolyte viscosity and rising electrode resistance, which lead to sluggish ion transfer and large voltage hysteresis. Advanced electrolyte design and feasible electrode engineering to achieve desirable performance at low temperatures are crucial for the practical application of rechargeable batteries. Herein, the failure mechanism of the batteries at low temperature is discussed in detail from atomic perspectives, and deep insights on the solvent–solvent, solvent–ion, and ion–ion interactions in the electrolytes at low temperatures are provided. The evolution of electrode interfaces is discussed in detail. The electrochemical reactions of the electrodes at low temperatures are elucidated, and the approaches to accelerate the internal ion diffusion kinetics of the electrodes are highlighted. This review aims to deepen the understanding of the working mechanism of low‐temperature batteries at the atomic scale to shed light on the future development of low‐temperature rechargeable batteries.

Low‐concentration electrolytes (LCEs) have attracted great attention due to their cost effectiveness and low viscosity, but suffer undesired organic‐rich interfacial chemistry and poor oxidative stability. Herein, a unique latent solvent, 1,2‐dibutoxyethane (DBE), is proposed to manipulate the anion‐reinforced solvation sheath and construct a robust inorganic‐rich interface in a 0.5 M electrolyte. This unique solvation structure reduces the desolvation energy, facilitating rapid interfacial kinetics and K+ intercalation in graphite. Additionally, enhanced anion‐cation interactions promote the formation of a thin and robust interfacial layer with excellent cycling performance of potassium‐ion batteries (PIBs). Graphite||perylene‐3,4,9,10‐tetracarboxylic dianhydride full cell exhibits a good capacity retention of 80.3% after 300 cycles, and delivers a high discharge capacity of 131.3 mAh g‐1 even at 500 mA g‐1. This study demonstrates the feasibility of latent solvent‐optimized electrolyte engineering, providing a pathway of superior electrochemical energy storage in PIBs.
