Abstract The development of high‐performance low‐temperature lithium metal batteries (LMBs) is hindered by severe dendrite growth and sluggish charge transfer, both which can be effectively addressed constructing a robust solid electrolyte interphase (SEI) with improved Li + transport kinetics. Compared to the soft organic SEI layers, LiF‐rich shows sufficient mechanical strength impede growth, however, its extremely low ionic conductivity (≈10 −13 S cm −1 ) hinders kinetics at temperatures. Herein, quasi‐ionic liquid (QIL, [Li(15‐crown‐5)]NO 3 additive rich NO − developed introducing 15‐crown‐5 into LiNO , induces in situ formation abundant N. Impressively, this N exhibits superior affinity lower diffusion barriers as learned from empirical computational studies, suggesting that it may powerful conquer temperature. With assistance QIL additive, Li/LiCoO 2 cells high mass loading 11.5 mg −2 demonstrate stable cycling for 250 cycles without any capacity decay ‐20 °C. This work opens an emerging avenue construct LMBs manipulating composition.
