Freestanding porous Mn2O3/carbon nanotube film cathodes for high-performance aqueous zinc-ion batteries

Abstract

Porous Mn₂O₃ nanocubes/single-walled carbon nanotube freestanding film electrodes were successfully prepared by a smart “coordination construction-pyrolysis-suction filtration” technology as advanced zinc-ion battery cathodes. Such rational design simultaneously addresses the key issues of volume expansion and poor conductivity in Mn₂O₃, enabling excellent rate capability and stable cycling.
