Abstract

Front cover image: Layered vanadates are promising materials for energy storage, but they still face challenges such as slow reaction kinetics and poor structural stability. In article cey2.647, Wang et al. synthesized [Me₂NH₂]V₃O₇ (MNVO) using a hydrothermal method. This layered vanadate features expended layer spacing and enhanced pH resistance. Both experimental and theoretical analyses reveal that the interlayer ionic and hydrogen bonding interactions, along with synergies from oxygen vacancy, enhance electronic conductivity and reduce the ion diffusion energy barrier. These improvements boost the material's capacity for H⁺/Zn²⁺ co-insertion in energy storage. As a result, aqueous zinc-ion batteries with MNVO as the cathode demonstrate high capacity and excellent cycling stability in acidic electrolytes.

封面图：层状钒酸盐是一种很有前途的储能材料，但仍面临反应动力学慢、结构稳定性差等挑战。在cey2.647中，Wang等人采用水热法合成了[Me2NH2]V3O7 （MNVO）。这种层状钒酸盐具有层间距扩大和耐pH性增强的特点。实验和理论分析均表明，层间离子和氢键相互作用以及氧空位的协同作用增强了电子电导率，降低了离子扩散能垒。这些改进提高了材料在储能中H+/Zn2+共插的能力。结果表明，以MNVO为阴极的水性锌离子电池在酸性电解质中表现出高容量和良好的循环稳定性。
