Polycarbonate-based solid electrolytes exhibit a high dielectric constant and remarkable oxidation resistance; nervertheless, their development is constrained by low room-temperature ionic conductivity poor electrode compatibility. To overcome these challenges, polymer electrolyte (PVT) was designed containing carbonate fluorinated side chain structures through an in situ copolymerization strategy. This structure not only enhances lithium salt dissociation ion migration but also forms stable LiF interface on the metal anode. The PVT demonstratesa of 1.71 × 10–4 S cm–1 at 30 °C, surpassing that PVE (without F-containing segments, 1.23 cm–1). Li|PVT|Li cell can cycle for more than 1200 h 0.1 mA cm–2-0.1 mAh cm–2, while Li|PVE|Li operates 1000 h. Moreover, capacity retention rate Li|PVT|LFP cells remains above 80% after 200 cycles 25 °C 0.1C.

Electric aircraft such as electric and vehicles play a key role in the future aviation industry, but they put forward huge requirements for battery energy density. However, current high-energy-density lithium technology still needs to be broken through. Herein, through molecular structure design of polymer electrolyte, strategy fast migration channel wide electrochemical window is proposed fabricate high-voltage-resistant solid electrolyte (HVPE) via situ polymerization. Thus, HVPE exhibits an ultrahigh Li+ transfer number (tLi+) 0.92 excellent 5.1 V match with high-voltage cobalt oxide (LCO) cathode. This conduction allows stable uniform plating stripping deposition more than 1000 h, which also reveals well-defined dual interfacial stabilization mechanism. These results endow assembled LCO|HVPE|Li cell cycles steadily 500 at 4.5 0.5C superior capacity retention 89.93%. Moreover, pouch rate up 94.01% after 50 cycles. More importantly, our provides new insights into structural fabrication strategies solid-state batteries.
