Aqueous Energy Storage Devices and Systems

A section of Batteries (ISSN 2313-0105).

Section Information

The global transition towards sustainable energy and electrified transportation faces significant challenges related to the safety, cost, resource availability, and environmental footprint of current energy storage technologies. The development of inherently safer, more cost-effective, and environmentally benign aqueous energy storage solutions represents a critical pathway to address these concerns, particularly for large-scale grid storage, renewable integration, and sustainable mobility.

On the one hand, this section aims to facilitate in-depth discussions on breakthroughs in materials chemistry, electrolyte chemistry, device design, performance optimization, safety mechanisms, and system integration of aqueous energy storage devices (including aqueous batteries like Zn-ion, Na-ion, and emerging chemistries, as well as aqueous supercapacitors). On the other hand, it aims to provide a platform for researchers and engineers to explore the latest advancements and real-world applications leveraging the unique advantages of aqueous electrolytes. By focusing on this rapidly evolving and strategically important field, this section seeks to accelerate progress and illuminate the future trajectory of aqueous energy storage.

The "Aqueous Energy Storage Devices and Systems" section covers the following topics in related research, development, and applications:

Aqueous electrolyte formulations and electrode materials (e.g., Zn-ion/Na-ion batteries, supercapacitors).
Charge storage mechanisms, interfacial phenomena, and voltage window optimization.
Strategies for mitigating corrosion, dendrite formation, and gas evolution.
Hybrid device architectures and solid-state aqueous systems.
Performance enhancement of energy/power density and cycle durability (e.g. Mn-based, V-based, halogen-based cathodes).
Integration with wearable electronics and flexible energy systems.
AI-driven design of aqueous electrolytes and electrode materials.
