Aqueous Zinc-Ion and Hybrid Energy Storage Systems
This community develops rechargeable battery and supercapacitor technologies based on zinc and other metal ions in aqueous electrolytes, primarily for stationary energy storage applications.
The research focuses on engineering zinc metal anodes and cathode materials—such as vanadium oxides, manganese sulfides, and porous carbons—to achieve high reversibility and stability. A significant portion of the work addresses electrolyte design, including hydrogels, water-in-salt solutions, and weakly solvating systems, to mitigate side reactions like hydrogen evolution and dendrite formation. The community also explores zinc-iodine and zinc-magnesium hybrid configurations, utilizing metal-organic frameworks and doped carbon structures to enhance ion transport and storage capacity.
The largest share of the community's output is found in zinc research, accounting for 5.7% of all zinc studies, with 11,240 papers in this group. Vanadium and magnesium also feature prominently, representing 2.4% and 1.6% of their respective element research, and contributing 1,905 and 1,775 papers here.
The community comprises 18,533 papers, with the most frequent publications appearing in Chemical Engineering Journal, Advanced Functional Materials, and Journal of Power Sources.
Recent work continues to refine electrolyte chemistries and separator materials, with specific attention to dual-salt systems, zwitterionic hydrogels, and boron-integrated cellulose nanofibers for stable zinc-ion and hybrid capacitor performance.
