Hybrid capacitive deionization (HCDI) is energetically and operationally favorable for Li+ extraction from salt lake brines. The bottlenecks of current LiMn2O4 (LMO)-based electrodes are their limited adsorption rate capacity, caused by disordered electron/ion transport channels insufficient ion-accessible sites. Inspired selective ion uptake processes in mangroves, we propose the strategy, fabricating ultrashort, vertically aligned electrode to enhance performance HCDI. self-supporting graphene/LMO/bacterial cellulose featuring (VGLB) possesses sturdy framework, excellent electrical conductivity, fast channels, abundant available sites, enabling an ultrahigh 2.6 mg g-1 min-1 capacity up 33.9 with a high retention 91.62% after 100 cycles. VGLB also manifests superior selectivity various simulated brines purity recovered solution over 85%. Most importantly, enables low-grade brine Jingbian oil gas-produced water. We conduct finite element simulations study distribution disclose how microstructure influences performance. This approach put forward avenue structure design efficient both lakes HCDI application.

Abstract Quasi‐solid‐state polymer electrolytes (QSPEs) have been considered as one of the most promising for high‐safety high‐energy‐density lithium metal batteries (LMBs). However, their inadequate mechanical properties and instability under high voltages pose significant challenges practical applications. Herein, robust antioxidative QSPEs are developed based on a polymer‐brush‐based rigid supporting film (BC‐ g ‐PLiMTFSI‐ b ‐PPFEMA, BC: bacterial cellulose, PLiMTFSI: poly(lithium (3‐methacryloyloxypropylsulfonyl) (trifluoromethylsulfonyl)imide), PPFEMA: poly(2‐(perfluorohexyl)ethyl methacrylate)). The BC nanofibril backbone can produce highly porous structure with outstanding strength. More importantly, PLiMTFSI‐ ‐PPFEMA side‐chains not only obviously increase conversion ratio easily oxidized monomers in QSPEs, but also possess strong interaction unstable electrolyte components. With such solid‐state electrolytes, Li/LiNi 0.8 Mn 0.1 Co O 2 full cell cathode loading (20.3 mg cm −2 ) exhibits specific discharge capacity 200.7 mAh −1 at 0.5 C demonstrates long lifespan 137 cycles retained 170.7 cut‐off voltage 4.5 V. 4.6 V, 147.0 after 187 be Li/LiCoO cells. This work provides feasible development strategy long‐cycling high‐voltage LMBs.
