Introducing a conductive carbon layer between the copper foil current collector and silicon active material effectively mitigates electrode damage battery capacity loss caused by uneven expansion. In this study, low-cost, environmentally friendly carbon-coated (CCF) is designed using zeolitic imidazolate framework 8-derived (ZPC) as source, polyethylenepyrrolidone (PVP) binder, deionized water solvent. The large surface area porosity of ZPC accommodate volume expansion silicon, thereby enhancing overall performance battery. bare experiences rapid decay, with failure occurring after just 75 cycles at 0.5 C. contrast, CCF maintains reversible 576.8 mAh/g even 200 cycles. demonstrates superior specific cycle stability in both rate cycling test. According to relaxation time distribution (DRT) analysis, porous on ensures excellent electrical contact Cu during cycling, facilitates uniform lithium insertion into prevents uncontrolled growth SEI layer, guarantees stable operation. This preparation process provides promising solution mitigate degradation

Zinc-bromine flow batteries (ZBFBs) hold great promise for grid-scale energy storage owing to their high theoretical density and cost-effectiveness. However, conventional ZBFBs suffer from inhomogeneous zinc deposition sluggish Br2/Br- redox kinetics, resulting in a short cycle life low power density. Herein, multiscale porous electrode with abundant nitrogen-containing functional groups is developed by growing zeolitic imidazolate framework-8 situ on graphite felts, followed facile carbonization process simultaneously tackle both the challenges. Theoretical experimental results reveal that exhibit adsorption toward atoms, while microstructures promote pore-level mass transport, thereby compact uniform deposition. In meantime, boosts reaction kinetics due its catalytic activity large surface area. As result, equipped optimized electrodes at negative positive sides can operate an ultrahigh current of 250 mA cm-2 maintaining efficiency 68.0%, far surpassing pristine felts (50.7%). Remarkably, battery exhibits excellent cycling stability over 2000 cycles without obvious decay. This study provides simple yet effective method developing high-performance critical challenges ZBFBs, promoting commercialization this promising technology.
