Advanced Energy Storage in Aqueous Zinc Batteries

Dear Colleagues,

Dear Colleagues, Renewable energy sources have intermittent features for their access, which can be easily influenced by external conditions. Thus, it is necessary to develop more appropriate technologies to capture and store such generated energy. In recent years, Zn metal has been shown to possess the advantages of cost-effectiveness, enhanced safety, outstanding stability, remarkable theoretical capacity (820 mAh g⁻¹), and lower redox potential (−0.76 V vs. SHE) in aqueous environments, making aqueous Zn-ion batteries a highly promising candidate in energy storage systems. However, the cycling performance of aqueous Zn-ion batteries is significantly affected by the presence of Zn dendrites and side reactions occurring at the Zn anode, leading to reduced stability and lifespan. Furthermore, their energy density is greatly affected by the lower capacity and lower electrode potential of the cathode. As a result, the practicality of aqueous Zn-ion batteries as energy storage systems is greatly diminished. In this Topic, we aim to promote the development of aqueous Zn-ion batteries, including the anode, cathode, electrolyte, and devices of aqueous Zn-ion batteries. As aqueous Zn-ion batteries have great potential in terms of application, this Topic will be of great interest for our readers. The Topic “Advanced Energy Storage in Aqueous Zinc Batteries” provides a platform to publish both reviews and original research papers (in support of the anode, cathode, electrolyte, and devices of aqueous Zn-ion batteries). Please join us in creating a diverse collection of articles for a variety of topics. We look forward to receiving contributions.
