Abstract Polyethylene oxide (PEO)‐based polymer solid electrolytes (PSE) have been pursued for the next‐generation extremely safe and high‐energy‐density lithium metal batteries due to their exceptional flexibility, manufacturability, lightweight nature. However, practical application of PEO‐PSE has hindered by low ionic conductivity, limited lithium‐ion transfer number ( t Li+ ), inferior stability with metal. Herein, an ultrathin composite solid‐state electrolyte (CSSE) film a thickness 20 μm, incorporating uniformly dispersed two‐dimensional fluorinated boron nitride (F‐BN) nanosheet fillers (F‐BN CSSE) is fabricated via solution‐casting process. The integration F‐BN effectively reduces crystallinity PEO matrix, creating additional channels that facilitate transport. Moreover, presence promotes inorganic phase‐dominated interface dominated LiF, Li 2 O, 3 N on anode surface, greatly enhancing electrode‐electrolyte interface. Consequently, CSSE exhibits high conductivity 0.11 mS cm −1 at 30°C, 0.56, large electrochemical window 4.78 V, demonstrates stable plating/striping behavior voltage mV 640 h, mitigating formation dendrites. When coupled LiFePO 4 , as‐assembled |F‐BN CSSE|Li battery achieves capacity 142 mAh g impressive retention rate 82.4% after 500 cycles 5 C. Furthermore, even ultrahigh 50 C, 37 achieved. This study provides novel reliable strategy design advanced high‐rate long‐life batteries.

Abstract Common anode materials in aqueous alkaline electrolytes, such as cadmium, metal hydrides and zinc, usually suffer from remarkable biotoxicity, high cost, serious side reactions. To overcome these problems, we develop a conjugated porous polymer (CPP) in-situ grown on reduced graphene oxide (rGO) Ketjen black (KB), noted C 4 N/rGO N/KB respectively, the alternative anodes. The results show that electrode delivers low redox potential (−0.905 V vs. Ag/AgCl), specific capacity (268.8 mAh g −1 at 0.2 A ), ultra-stable fast sodium ion storage behavior (216 20 ) 2 M NaOH electrolyte. assembled N/rGO//Ni(OH) full battery can cycle stably more than 38,000 cycles. Furthermore, by adding small amount of antifreeze additive dimethyl sulfoxide (DMSO) to adjust hydrogen bonding network, low-temperature performance electrolyte (0.1 DMSO/2 NaOH) is significantly improved while evolution inhibited. Consequently, cell exhibits an energy density 147.3 Wh Kg ultra-high cycling stability over wide temperature range −70 45 °C.
