Abstract The practical application of all‐solid‐state lithium metal batteries (ASSLMBs) is limited by (Li) anode instability including Li dendrite formation and deteriorating interface with electrolytes. Here, a functional additive, isosorbide mononitrate (ISMN) non‐resonant structure (O 2 −N−O−) reported, which improves its reactivity utilized to build stable N‐rich solid electrolyte interface, effectively alleviating side reactions for poly(vinylidene fluoride) (PVDF)‐lithium bis(trifluoromethane sulfonyl) imide (LiTFSI)‐based (PLE‐ISMN). In addition, the ion‐dipole interaction between ISMN ions facilitates dissociation LiTFSI form carrier ions, improving ionic conductivity (4.4 × 10 −4 S cm −1 ) transference number (0.50) PLE‐ISMN. Consequently, Li/Li symmetric cell delivers high critical current density 2.0 mA −2 stripping/plating cycling over 5000 h capacity 1.0 mAh . Moreover, Li|LiFePO 4 an excellent initial discharge 154.0 g outstanding retention 88.9% after 500 cycles at 0.5 C. Li|LiNi 0.8 Co 0.1 Mn O also exhibits good performance 4.4 V 1
