Summary: In this study, Fe-doped (NH4)2V12O27·xH2O was synthesized using solvothermal method which greatly enhanced material's electrochemical performance. The resulting product showed remarkably high capacity of 165 mA h g-1 at 50 mA g-1 and ultrahigh stability with 74.2% retention over 1000 cycles at 1 A g-1. This improvement is attributed to increased intrinsic conductivity from Fe doping which promotes absorption and release kinetics of Zn2+ and prevents gradual dissolution of V-O layer.

Summary: Based on first-principles calculations, this paper proposes hydrogenated V2O5 (HV2O5) nanospheres as a high capacity cathode for aqueous rechargeable Zinc-ion batteries. The electrostatic interaction and Zn-ion diffusion energy barrier in V2O5 are effectively reduced after hydrogenation. The experimental results demonstrate that HV2O5 exhibits high peak capacities, high rate capacity, and excellent cycle lifespan. Furthermore, the mechanism of ions-diffusion in different charge and discharge states is studied, indicating the dual-ion energy storage mechanism of HV2O5 attracting both Zn ions and H ions during discharging.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
