Special Issue Information

Dear Colleagues,

The development of next-generation electrochemical energy storage (EES) is a necessity in order to supply sustainable energy that can maintain societal resilience. As a sustainable and clean technology, EES has been among the most valuable options for meeting increasing energy requirements and carbon neutralization. In recent years, the increasing demand for high-capacity and safe EES has attracted great attention toward aqueous rechargeable batteries boasting a low cost, environmental benignity, or both. Consequently, there is an urgent need to develop new materials and technologies for aqueous batteries with higher energy densities.

In this Special Issue, we wish to cover the most recent advances in battery chemistry for aqueous rechargeable batteries by hosting a mix of original research articles and reviews. The topics of interest for this Special Issue include (but are not restricted to) the following:

  • Electrochemical reactions in aqueous rechargeable batteries;
  • Electrocatalytic reactions in aqueous rechargeable batteries;
  • Materials or electrolyte chemistry for advanced aqueous rechargeable batteries.

In this work, novel sodium-intercalated vanadium oxide nanowire electrode materials (NaXV@CC) were successfully designed as cathode materials for Aqueous Zinc-Ion Batteries (AZIBs) through a two-step electrochemical process. The optimized electrode material, Na30V@CC, exhibited superior capacity, excellent rate capability, and outstanding stability. The intercalation of sodium ions into the nanowire lattice induced a significant transformation in the overall nanostructure, leading to altered nanowire morphology. This unique structural design provided abundant active sites and efficient ion transport pathways, thereby enhancing the overall electrochemical performance. The charging and discharging capacities were 343.3 and 330.4 mAh·g−1 at 0.2 A·g−1, respectively, and the capacity was maintained at 90 mAh·g−1 at 8 A·g−1. The battery demonstrated exceptional capacity retention over 3000 cycles at 5 A·g−1, highlighting its long-term electrochemical stability. Moreover, the overall battery reaction was governed by a combination of diffusion and surface processes. The Na30V@CC battery system demonstrated reduced reaction impedance and improved zinc ion diffusion rates. This study offers valuable insights into enhancing the electrochemical performance of vanadium-based cathodes in AZIBs. Full article
