Solid-state electrolytes based on in situ ring-opening polymerization of 1,3-dioxolane (DOL) have attracted widespread attention Li metal batteries because their high interface compatibility. However, its conventional cationic mechanism frequently results the formation long polymer chains during polymerization, thereby impeding Li+ transport. Here, we regulate ring opening DOL by introducing N,N-dimethyltrifluoroacetamide (FDMA), thus avoiding chains. Meanwhile, FDMA can derive a stable SEI rich LiF electrochemical cycling, improving stability and suppressing dendritic growth. Therefore, full battery with LiFePO4 as cathode achieve capacity retention rate 83.9% after 400 cycles at 5.0 C. At -20 °C, Li∥LiFePO4 provide 137 mAh g-1. The solvent-induced strategy provides promising new avenue for designing solid electrolyte temperature resistance.

Abstract Low room temperature ionic conductivity and interfacial incompatibility severely hinder the further application of polymer electrolytes in lithium metal batteries. Here, a novel shear‐oriented (SO) aliphatic ketone‐carbonyl‐based liquid crystal composite solid electrolyte (FL 7 M 3 @CSPE SO ) is prepared by situ thermal‐polymerization monomer (FPZ‐LC, FL) N, N' ‐Methylenebisacrylamide (MBA, M) on cellulose nanofiber (CNF) presence triethylene‐glycol‐dimethyl‐ether (G salt (lithium bis(trifluoromethanesulphonyl)imide, LiTFSI). The high polarity keto‐carbonyl groups improves dissociation ability salt. highly oriented crystals provide rapid ion transport channels. Thus, FL achieves 10 −4 S cm −1 lithium‐ion transference number (t Li+ 0.52 at 30 °C. Besides, formed stable interface layer effectively inhibits growth dendrites. assembled Li/FL /Li cells operate stably over 5500 h 0.05 mA −2 (30 °C). Impressively, /NCM811 exhibits long‐term cycle 1200 with capacity retention 92% under C 4.4 V (−5 This work not only highlights advantages improving capacity, but also provides design strategy for advanced suitable lower high‐voltage solid‐state

Abstract Solid‐state lithium batteries have attracted significant interest due to their potential enhance the safety and energy density of modern storage systems. However, challenges such as low ionic conductivity poor interfacial compatibility hindered widespread adoption. In this study, a novel hydrogen‐bonded organic framework (HOF) composite polymer electrolyte (HCPG@SPE) is developed by integrating trimesic acid melamine‐based HOFs with natural matrix composed gelatin chitosan. The hydrogen‐bonding interactions between HOF in HCPG@SPE impart remarkable mechanical strength thermal stability. Additionally, weak lithium‐ions, its anion adsorption capacity, effectively generates more free facilitating migration while inhibiting movement. Electrochemical tests revealed that exhibited high (5.74 × 10⁻ 3 S cm⁻¹ at 30 °C), favorable lithium‐ion transference number (0.71), an extended electrochemical stability window (5.4 V). metal utilizing achieved outstanding performance, LFP| HCPG@SPE| Li cells retaining 98% capacity after 1000 cycles 5 C, NCM811| demonstrating stable cycling for 700 1 C. results suggest HOF‐based holds promise next‐generation high‐performance solid‐state batteries.
