Special Issue Information

Dear Colleagues,

Aqueous zinc-based batteries (AZBs) have emerged as a highly promising candidate for next-generation energy storage, driven by the compelling advantages of the metallic zinc anode, including high theoretical capacity, low redox potential, intrinsic safety, abundance, and eco-friendliness. However, their widespread commercialization is hindered by critical challenges across the entire battery system. These include zinc anode issues such as dendrite growth and hydrogen evolution reaction, as well as critical obstacles at the cathode like structural instability and dissolution, and limitations of aqueous electrolytes such as a narrow electrochemical stability window. This Special Issue, “Progress in Aqueous Zinc-Based Batteries,” aims to capture the latest breakthroughs in overcoming these multifaceted hurdles. We invite original research and reviews that explore innovative material design, advanced characterization techniques, and novel device engineering for high-performance AZBs. Topics of interest span from fundamental mechanistic studies of electrode–electrolyte interfaces to the development of practical battery configurations. We hope this collection will provide a platform for sharing cutting–edge discoveries and foster further development toward the large–scale application of this sustainable battery technology.

Aqueous zinc–manganese dioxide (Zn–MnO2) batteries are undergoing a paradigm shift from traditional ion-insertion mechanisms to a reversible deposition/dissolution process. By leveraging a two-electron transfer (Mn2+/MnO2), this electrolytic system achieves a high theoretical capacity of 616 mAh g−1 and a theoretical operating voltage of 1.99 V. However, the accumulation of dead Mn, electrically isolated inactive phases, and dynamic interfacial pH fluctuations remain critical barriers to cycle life and practical energy density. This review systematizes a trinitarian strategy to overcome these bottlenecks, focusing on interfacial engineering, redox mediator-assisted recovery, and advanced electrode architectures. We evaluate how anion engineering and pH-buffering stabilize reaction pathways, and how diverse mediators (e.g., halogens, metal ions, and organic molecules) chemically rescue inactive manganese. Furthermore, we examine the integration of 3D carbon networks and low-cost hybrid electrodes to sustain high-areal-capacity deposition. To elucidate these complex mechanisms, we highlight multiscale analytical approaches combining synchrotron X-ray techniques and density functional theory (DFT). Finally, we outline a roadmap for applications ranging from grid-scale flow batteries to flexible wearable electronics. This work provides a comprehensive perspective on realizing sustainable, safe, and high-performance zinc-based energy storage. Full article
