Abstract Composite solid‐state electrolytes (CSSEs) that combine the benefits of inorganic and polymer hold great potential for lithium metal batteries (SSLMBs) due to their high ionic conductivity superior mechanical properties. However, overall performance is severely hindered by several practical challenges, including component aggregation, poor interface behavior, limited Li + transport. Here, a unique ultrathin coating triaminopropyl triethoxysilane with bifunctional structure introduced effectively bridges fillers (Li 1+x Al x Ti 2‐x (PO 4 ) 3 , LATP) polyvinylidene fluoride hexafluoropropylene /polyethylene oxide matrix, thereby enabling high‐performance CSSEs (referred as SLPH). This design prevents LATP particle agglomeration, improves interfacial compatibility, ensures enrichment fast transport within SLPH. Consequently, SLPH exhibits low conduction energy barrier ( E = 0.462 eV), desirable (4.19 × 10 −4 S cm −1 at 60 °C), transference number 0.694). As result, SSLMBs SLPH, Li| |Li symmetric cells, LiFePO | coin‐type, pouch demonstrate rate capability long‐time cycling stability. work underscores significance surface functionalization create stable solid‐solid enhance conduction, paving way in SSLMBs.

Composite solid electrolytes are gaining interest regarding their use in Li-metal solid-state batteries. Although high ceramic content improves the electrochemical stability of ceramic-rich composite separators (C-SCE), polymeric matrix also plays a vital role. In first generation C-SCE with PEO-based matrix, addition 90–95 wt% Li6.45Al0.05La3Zr1.6Ta0.4O12 (LLZO) does not make stable for cell cycling high-voltage (HV) cathodes. For next iteration, objective was to find an HV-stable C-SCEs. Herein, we report results on optimizing different ceramics and polymers which can craft system towards better NMC622-based Both LLZO Li1.3Al0.3Ti1.7(PO4)3 (LATP) were utilized as components separators. Poly(diallyldimethylammonium) bis(trifluoromethanesulfonyl)imide (PDDA-TFSI) poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) used “polymer/LiTFSI/plasticizer”-based matrix. The initial phase selection criteria separator involved assessing mechanical ionic conductivity. Two optimized formulations then tested both Li metal HV showed that Li/NMC622 cells LP70_PVDF_HFP LZ70_PDDA-TFSI exhibited more performance compared those LZ90_PEO300k-based
