Summary: Zinc (Zn) and nitrogen (N) co-doped ZIF-8 derived hollow carbon (ZHC) is reported as a promising separator coating for lithium-sulfur batteries (LSBs) to control the shuttle effect. The presence of Zn and N in the nanohollow carbon structure helps mitigate polysulfide (PS) diffusion in LSBs, while the hollow interior of the carbon acts as a PS pocket to physically capture the PS. The ZHC shows promising performance with higher initial specific capacity and cycling stability compared to the parent ZIF-8.

Summary: CoS2-embedded nitrogen-doping carbon nanotubes with hollow polyhedron (CoS2/NCNHP) derived from ZIF-8@ZIF-67 were synthesized as an HER electrocatalyst. The pyrolysis of ZIF-8@ZIF-67 effectively retained porous structures, providing a carrier for CoS2 nanoparticles, and the generation of NCNTs enhanced the electrical conductivity. The synergistic effect between CoS2 and NCNTs facilitated favorable electrochemical properties. The CoS2/NCNHP catalyst exhibited low overpotential and maintained high current density after long electrolysis.

Summary: Black phosphorus (BP) has shown promise as a high-performance alkali-ion battery anode due to its high specific capacity and fast alkali-ion transport. However, the batteries face serious irreversible losses and poor cycling stability, which are attributed to alloying. By studying the degradation mechanisms of BP anodes, researchers can develop protocols to improve the performance of next-generation high-capacity alkali-ion batteries.

Summary: Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition. Based on underpotential deposition (UPD), an escort effect of electrolyte additives for uniform Zn deposition at the atomic level is proposed. With nickel ion (Ni2+) additives, metallic Ni deposits preferentially and triggers the UPD of Zn on Ni, facilitating firm nucleation and uniform growth of Zn while suppressing side reactions. The optimized cell operates for over 900 h at 1 mA cm(-2), more than 4 times longer than the blank one, indicating the significance of this work.

Summary: Zinc-ion batteries (ZIBs) have potential for use in grid-scale energy storage systems, but suitable cathode materials are needed. MnO2-based cathodes are emerging as promising contenders due to their availability, safety, and stable output voltage. However, their slow kinetics caused by low electrical conductivity and mass diffusion rate are a challenge for rapid charging devices. This study proposes a sodium-intercalated manganese oxide (NMO) with 3D varying thinness carbon nanotubes (VTCNTs) networks as free-standing, binder-free cathodes, which overcome the challenges and achieve excellent capacity and long-term cycling stability.
