Multivalent Metal-Ion Batteries and Electrolyte Chemistry
This community focuses on the development of rechargeable battery systems using multivalent metal anodes, specifically magnesium and aluminum, and the electrolyte chemistries required to make them function.
The research centers on designing cathode materials, metal anodes, and electrolytes for magnesium-ion, aluminum-ion, and aluminum-air batteries. Key technical challenges addressed include improving charge transfer kinetics, stabilizing the solid-electrolyte interphase, and managing dendritic growth in metal anodes. The work frequently involves aqueous and organic electrolytes, ionic liquids, and eutectic solvent systems to enhance reversibility and cycle life. Specific material systems include Prussian blue analogues, chalcogenides, and carbon-based cathodes, with a strong emphasis on understanding solvation structures and interfacial chemistry to enable high-performance energy storage devices.
The largest share of the community's output is found in magnesium research, accounting for 1.4% of all magnesium research, with 2,149 papers in this group. Lithium and aluminum research also contribute significantly, with 826 and 509 papers respectively.
The community comprises 5,827 papers, publishing most frequently in the Journal of The Electrochemical Society, Journal of Power Sources, and Electrochimica Acta.
Recent work continues to focus on electrolyte design for magnesium and aluminum systems, including the use of eutectic solvents, weakly coordinating co-solvents, and AI-assisted solvent discovery to improve anode stability and interfacial performance.
