Abstract Fast‐charging capability and calendar life are critical metrics in rechargeable batteries, especially silicon‐based batteries that susceptible to sluggish Li + desolvation kinetics HF‐induced corrosion. No existing electrolyte simultaneously tackles both these pivotal challenges. Here we report a microscopically heterogeneous covalent organic nanosheet (CON) colloid for extremely fast‐charging long‐calendar‐life Si‐based lithium‐ion batteries. Theoretical calculations operando Raman spectroscopy reveal the fundamental mechanism of multiscale noncovalent interaction, which involves mesoscopic CON attenuating microscopic ‐solvent coordination, thereby expediting kinetics. This design enables capabilities full cell, at 8 C (83.1 % state charge) 10 (81.3 charge). Remarkably, demonstrates record‐breaking cycling performance (capacity retention 92.39 after 400 cycles). Moreover, benefiting from robust adsorption mesoporous towards HF water, notable improvement is observed cell. study highlights role electrolytes enhancing Li‐ion Our work offers fresh perspectives on with interactions, providing insightful guidance development alkali‐ion/metal operating under harsh environments.

Current lithium batteries experience significant performance degradation under extreme temperature conditions, both high and low. Traditional wide-temperature electrolyte designs typically addressed these challenges by manipulating the solvation sheath selecting solvents with melting/boiling points. However, solvent-mediated solutions, while effective at one extreme, invariably fail opposite end due to inherent difficulties in maintaining solvent stability across wide temperatures. Herein, we report use of main salt simultaneously address interfacial extremely low This approach is different from conventional strategies. As a proof concept, utilized nitrate (LiNO3) establish an anion-controlled structure electric double layer. The formulated electrolytes exhibited remarkable extremes, retaining 56.1% capacity -60 °C sustaining 400 stable cycles 80 °C. In contrast, based on current strategies failed operate could not exceed 50 By shifting focus rather than solvent, our work offers possibility addressing enduring broad range.
