Summary: This study successfully prepared a composite material by carbonization of V-MIL-101, in which vanadium oxide nanoparticles and nanoporous carbon network were embedded, significantly improving the electrochemical performance of the material as a cathode in an aqueous Zn-ion battery system. The loading of manganese oxide further stabilized the composite material and improved the rate capability of the cathode material in the aqueous zinc ion battery. The MnO2@NVC composite cathode material exhibited a capacity of 299 mAh/g at a 0.1C rate for 100 cycles, benefiting from the synergistic effect of the high conductivity of vanadium oxide nanoparticles and the suitable voltage of MnO2. The materials showed superior capacity retention and better cycling performance compared to unmodified vanadium oxide nanoparticles on a carbon substrate as cathode material. Comparative morphological and electrochemical studies confirmed the improved performance, suggesting that the vanadium oxide nanoparticles anchored on a high surface area carbon network intertwined with manganese oxide nanowires provide enhanced conductivity.

Summary: In this study, different MnO2 polymorphs were used as cathodes in zinc-ion batteries. The results showed that regardless of the polymorph, they exhibited similar electrochemical behavior and charge-discharge performance in weak acidic solutions, and underwent irreversible changes. These changes were caused by the dissolution and re-deposition of MnO2 and the formation of new manganese and zinc compounds. The newly formed MnO2 phase was amorphous and covered the surface of the initial crystalline particles, affecting the electrochemical behavior of the batteries. The electrochemical response of the MnO2 electrodes was strongly pH dependent.

Summary: The study proposes mixed sodium manganese oxides as potential cathode materials for sodium-ion batteries with advantages in electrode voltage, capacity, and sodium-ion diffusion rate, based on first-principles calculations. Through identifying intermediate phases during Na insertion/extraction, the study shows an increase in electrode voltage and specific capacities by mixing due to extending the lower limit of Na content. Furthermore, investigation of sodium-ion diffusion reveals fast migration within the S-shaped tunnel and moderate migration within the small-sized tunnel in these compounds.

Summary: Rechargeable aqueous zinc-ion batteries (AZIBs) have gained much interest due to their high energy density, safety, and low cost. However, issues such as anode side reactions, passivation, corrosion, hydrogen evolution, and Zn dendrite growth continue to hinder their widespread application. This review presents metal-organic frameworks (MOFs) as potential solutions to these problems by enhancing the performance of Zn anode materials, electrolytes, and electrolyte additives through their porous structure and active sites. The review also proposes directions for the rational design of MOF-based Zn anodes and understanding the mechanisms affecting Zn2+ solvation in high-performance AZIBs, aiming to extend the cycling lifetime and promote the commercialization of AZIBs.

Summary: Zinc telluride (ZnTe) microspheres were synthesized in a polyol system using a hot injection method and different amounts of poly(N-vinyl-2-pyrrolidone) (PVP, K-90). The size of the smallest ZnTe microspheres obtained in this study was 634 nm, with a reaction time of 48 h and 518 mg of PVP. The formation process of ZnTe microspheres was evaluated by conducting experiments from 0.2 h to 48 h, revealing that nucleation and growth of ZnTe occurred at the tips of Te rods in a PVP-contained polyol system.

Summary: In this study, binder-free nanocluster Cr-doped NiO thin film electrodes were developed on flexible stainless-steel foils using a one-step co-sputtering technique. The unique nanocluster structure of the electrodes resulted in reduced ion diffusion length, improved charge transport, and increased accessibility of ions onto the active surface area. The electrodes exhibited a high areal capacitance of 429 mF cm-2 (251 mC cm-2) in a 2 M KOH aqueous electrolyte. The developed asymmetric coin cell supercapacitors demonstrated exceptional cycling stability even after 5,000 cycles and good electrochemical performance with minimal capacitance fading after 720 hours of aging test.

Summary: New hybrid catalysts based on molecularly dispersed nickel complexes on N-doped graphene were developed for electrochemical CO2 reduction (ECR). The nickel complexes with N-H groups showed current enhancement in the presence of CO2, while the absence of N-H groups resulted in no change. All three nickel complexes were successfully immobilized on nitrogen-doped graphene (NG) and exhibited satisfactory CO2-to-CO reduction. The N-H moiety from the ligand was found to be less important in the heterogeneous aqueous system.

Summary: Zinc (Zn) is a promising material for use as an anode in water-based rechargeable batteries. However, the high reactivity of water leads to corrosion and dendrite formation on the Zn surface during charge-discharge cycles. To address these issues, a covalent organic framework (COF) was used to fabricate an artificial solid electrolyte interphase (ASEI) protective layer on the Zn surface.

Summary: Due to its reversibility and stability, DMSO electrolyte is considered a promising nonaqueous electrolyte for rechargeable zinc-ion batteries (ZIBs). However, the performance of ZIBs with DMSO electrolyte and MnO2 cathode is inferior to aqueous Zn-MnO2 systems. This study investigates the impact of water on the performance of DMSO-based ZIBs, finding that the addition of even a small amount of water improves their performance by altering the intercalated phase of Zn2+ ions and facilitating solid-phase diffusion and surface kinetics.
