Intermolecular Interaction Adjustment for LiNO3 Solubility Promotion toward High-Performance Li||NCM811 Batteries

without compromising the compatibility of the electrolyte with the lithium metal anode. The introduction of the "Small-Sized Carrier" additive system simultaneously enhances the stability of the electrode-electrolyte interfaces and optimizes the solvation structure of the electrolyte. As a result, the electrolyte developed through this strategy demonstrates outstanding electrochemical performance, with Li||NCM811 batteries achieving a capacity retention of 83.8% after 600 cycles. This work provides an insightful approach to designing advanced electrolytes tailored to high-energy-density lithium metal batteries (LMBs).
