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.
期刊介绍：
Carbon Energy is an international journal that focuses on cutting-edge energy technology involving carbon utilization and carbon emission control.
