Aqueous Zinc-Based Batteries: Issues and Opportunities

Dear Colleagues,

The transition towards clean energy necessitates advancements in large-scale energy storage technologies. Current organic-based batteries pose significant safety risks that render them unsuitable for widespread application. In contrast, aqueous batteries, which utilize water as a solvent, emerge as a promising and exceptionally safe alternative. Among these, zinc-based batteries stand out for their optimal balance of energy density, reversibility, and affordability. The growing demand for large-scale energy storage is poised to drive the evolution of these batteries, pushing their development to new heights.

However, these batteries currently face issues such as limited output voltage, inadequate anode utilization, and a narrow electrochemical stability window, among others. Addressing these obstacles necessitates improvements at both the material level and within the broader battery system design. This Special Issue aims to shed light on recent progress in the field of aqueous zinc-based batteries, spanning electrode innovations, electrolyte modifications, and the introduction of novel battery systems. Our goal is to provide valuable insights and guide future research in this promising area.

Potential topics for this Special Issue include, but are not limited to, the following:

• Innovations in electrodes and electrolytes for zinc-based batteries;
• Progress and challenges in zinc-based alkaline batteries;
• Advances in zinc air/oxygen batteries;
• Exploration of zinc gas batteries;
• Development of flexible zinc-based batteries;
• Environmental adaptability of aqueous zinc-based batteries;
• hybrid aqueous batteries incorporating zinc ions;
• Dual-ion battery systems utilizing zinc anodes;
• Optimization strategies aimed at enhancing the longevity and reliability of aqueous zinc-based batteries;
• Considerations for the industrialization of aqueous zinc-based batteries, including scalability, cost effectiveness, and market potential.
