Synthetic Engineering of Manganese Oxide–Carbon Nanocomposites for Maximized Metal Utilization in Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐pot metal–ammonia synthesis enables uniform Mn2O3 nanoparticle deposition on activated carbon, yielding composites with excellent electrochemical performance in supercapacitors. The method maximizes manganese utilization, eliminates toxic solvents, and achieves 34% of the theoretical maximum capacitance, significantly outperforming existing Mn–C ...
