Herein, a regenerated-cellulose/graphene (RCG) separator is developed to improve the stability of the Zn anode and extend the lifespan of ZIBs. The glucose units in cellulose chains can modify the solvation configuration of Zn²⁺ ions, facilitating the Zn²⁺ ions transfer and regulating Zn deposition kinetics. Meanwhile, the graphene additive induces Zn (002) oriented deposition by forming a low lattice mismatch interface between the separator and Zn (002) crystal plane. Furthermore, the hybrid separator exhibits significantly higher tensile strength (91.23 MPa) compared to previously reports, which is a crucial for preventing short circuits caused by zinc dendrites or external force during cell operation. Accordingly, the Zn anode with the RCG separator achieves a record operational lifetime of 7000 h at 0.5 mA cm⁻², surpassing previously reported results. Moreover, the zinc-ion hybrid supercapacitor with the RCG separator exhibits a high capacity retention of 81.62 % after 10000 cycles.

Herein, a dual-reactive siloxane agent is introduced into an in-situ polymerized polymer electrolyte as a bridging promoter, enabling ultra-conformal interfacial contact with rapid ion transport kinetics at Li metal anode. This strategy transforms the inactive LiOH layer on the lithium metal surface into Li–O–Si bonds, achieving both in-situ grafting and self-assembly.

Thus, this strategy facilitates a seamless interfacial connection between the electrolyte and lithium metal anode, optimizing ionic conductivity and significantly enhancing the air stability of Li metal anodes.

In this work, Cu, Zn and Zn/Cu particles in the absence and the presence of 1,3,5-benzenetricarboxylic acid (BTC) have been synthesized via binder-free electrodeposition onto an indium tin oxide (ITO) surface as electrocatalysts to improve the hydrogen evolution reaction (HER) in acidic media.

Consequently, a low-cost and robust electrocatalyst (Zn/Cu-BTC/ITO) with enhanced catalytic performance toward the HER was synthesized. Finally, this work emphasizes how electrochemically modified surfaces, created using low-cost metals and straightforward sustainable synthesis methods, can generate atomically dispersed active sites that enhance both electrocatalytic activity and stability.
