Abstract Micron‐sized silicon (µSi) anodes hold great promise for high‐energy lithium‐ion batteries (LIBs). However, the rechargeable cyclability of µSi at sub‐zero Celsius, especially below −20 °C remains challenging, caused by severe volume change and cracking solid electrolyte interphase (SEI) during cycling. Here, low‐temperature µSi‐based LIBs is realized using an featured with temperature‐adaptive ion‐dipole interactions. The synergistic effect methyl group as a weak electron donor electronegative fluorine atoms endows difluoroacetate (MDFA) binding affinity Li + . Moreover, between oxygen in both MDFA fluoroethylene carbonate (FEC) decreases lower temperatures, accompanied temperature‐responsive enhancement ‐anion coordination. Thus, MDFA/FEC exhibits extraordinary contact ion pairs‐dominated solvation structure subzero which facilitates desolvation formation thin, robust inorganic‐rich SEI. As expected, show record‐breaking capacity 786 mAh g −1 after 100 cycles −40 under 0.1 A , full cells display impressive rechargeability °C. This work paves way extending applications to extreme cold conditions.
