Abstract To address the challenges of recycling and high‐value utilization waste fluororubbers, an effective method is reported for producing novel photocurable vinyl‐terminated liquid fluororubbers (VTLF) with elevated fluorine content (63.1%), superior temperature resistance ( T 10% = 335 °C) from commercial fluororubbers. The approach employs a streamlined, multifaceted system (oxidative degradation/condensation reaction) integrating microwave, mechanical, steady‐state fields. This facilitates both efficient transformation Initially, undergo controlled/oxidative degradation induced by alkali hydrogen peroxide to yield carboxyl‐terminated (CTLF). Subsequently, condensation reaction efficiently converts carboxyl groups into photoreactive vinyl groups. Ultimately, environmentally friendly photocuring VTLF achieved. nonthermal effects microwave fields reduce total process time just 1 h. resulting photocured exhibits not only comprehensive properties conventional but also excellent chemical stability unique light transmittance (94.21%). study proposes green, straightforward upcycling strategy within circular economy framework mitigate environmental issues associated rubber's covalent crosslinking. Furthermore, it opens avenues designing synthesizing fluoropolymers diverse applications.

Abstract Solid polymer electrolytes (SPEs) are promising for high‐energy and high‐safety solid‐state lithium metal batteries (LMBs). Here, a polycationic solid electrolyte (PCSE) is described that leverages the inherent high thermal/chemical stability of domain anion trapping (FMAT) effect another fluorinated microdomain stable fast‐charging high‐voltage LMBs. Specifically, while imidazolium backbone ensures segmental flexibility facilitating Li + mobility, effectively traps bis(trifluoromethanesulfonyl)imide anions by strong dipole interactions, imparting localized solvation restricted mobility anions, as well improved oxidation stability. As result, PCSE exhibits ionic conductivity 1.4 mS cm −1 , transference number 0.50, wide electrochemical window ∼5.5 V at 25 °C. By way in situ thermal polymerization within assembled cells, enables ultra‐stable cycling Li|LiNi 0.8 Co 0.1 Mn O 2 cells with capacity retention 98.1% after 500 cycles 0.2 C ambient temperatures.

The rapid expansion in lithium battery production and disposal presents considerable sustainability challenges, emphasizing the critical need for recycling. However, current methods predominantly focus on metals from cathodes, while electrolytes have rarely been recycled. Here, we propose an innovative closed-loop design solid polymer (SPEs), enabled by reversible catalysis of bis(trifluoromethane) sulfonimide (LiTFSI) both polymerization depolymerization. formation a hydrogen-bonded adduct between TFSI- alcohol initiates situ ring-opening Li+-activated trimethylene carbonate (TMC), generating well-defined SPEs. With delicate structural optimization, SPE achieves outstanding ionic conductivity 1.62 × 10-3 S cm-1 at room temperature with robust high-voltage stability up to 4.7 V. assembled Li||NCM811 demonstrates promising cycling 88% capacity retention over 100 cycles. Upon end-of-life, LiTFSI facilitates selective depolymerization polycarbonate-based 180 °C without introducing external catalysts, recovering TMC monomer (>90%) (>98%) reuse. This work highlights significant advance recyclable SPEs vital step toward sustainable technology.
