Summary: This study presents the construction of excellent dual-functional electrochromic Zn batteries (EZB) by balancing electrochemically deposited NiO with Zn anode. The optimized deposition conditions lead to nanoporous NiO film, which enables faster switching for electrochromism and higher capacity for charge storage. The alkaline EZB outperforms the mild counterpart due to the formation of a larger amount of Ni3+ species. This work demonstrates the outstanding performance and dual functionalities of the constructed EZB.

Summary: In this paper, Zn-MOF-74-derived carbon nanorods are designed as a host for Se to improve the performance of K-Se battery systems. The obtained carbon matrix shows high conductivity and structural robustness, leading to better Se utilization, higher transfer rate, and less frequent polyselenide dissolution. Furthermore, the carbon matrix is capable of accommodating the volumetric change of Se and delivers outstanding electrochemical performance.

Summary: Metal-organic frameworks (MOFs) are promising materials for next-generation batteries due to their high surface area, well-defined metal centers, and organic linkers. In this study, a Ni-3(HHTP)(2) MOF was synthesized at the air-liquid interface and used as an electrode in lithium batteries. The MOF film protected the copper collector from oxidation and exhibited improved coulombic efficiency with the inclusion of crystallization time. The use of Langmuir technique allows for the testing of MOF-based materials without the need for additives in the electrodes.

Summary: Water-induced parasitic reaction and zinc dendrite growth caused by uneven electric field distribution on the surface of zinc anode are the most controversial problems in practical applications of zinc-nickel rechargeable batteries for large-scale energy storage. In this study, Bi2O3/In2O3 doped ZnO@C synthesized by MOF pyrolysis demonstrated good cycle stability, inhibiting hydrogen evolution and achieving uniform zinc deposition. The Bi2O3 doped ZnO@C (BCZ) and In2O3 doped ZnO@C (ICZ) electrodes delivered high capacity and long-term cyclic stability, providing new ideas for anode synthesis in aqueous rechargeable zinc metal batteries.

Summary: Transition metal nitride/carbide (TMN/C) materials have attracted significant attention as low-cost electrocatalysts for the hydrogen evolution reaction (HER). In this study, Fe-N doped WC and Fe-C doped WN nanoarrays were prepared by a switchable WO3-based in situ gas-solid reaction. The amount of ferrocene used in the reaction was found to effectively control the codoping and phase transition of the materials. The resulting Fe-N-WC and Fe-C-WN exhibited excellent electrocatalytic performance for HER in acid and alkaline electrolytes, respectively.

Summary: Transition metal nitride/carbide (TMN/C) has been actively investigated as low-cost electrocatalysts for hydrogen evolution reaction (HER) due to their Pt-like properties. However, pure TMN/C has strong hydrogen adsorption and lacks active centers for water dissociation. In this study, we developed a switchable WO3-based gas-solid reaction for preparing sophisticated nanoarrays of Fe-N doped WC and Fe-C doped WN. The resulting Fe-C-WN and Fe-N-WC showed robust electrocatalytic performance for HER in alkaline and acid electrolytes, respectively, and the combination of morphological, phase, and electronic effects contributed to their superior activity.
