Achieving High-Performance Supercapacitors by Constructing Porous Zinc-Manganese Oxide Microstructures.

Porous zinc-manganese oxide (ZnMn₂O₄) microstructures are prepared by calcination using a precursor method, and the material is successfully applied as the supercapacitor electroactive materials in a three-electrode cell. Due to the unique micro/nanostructure, the as-prepared sample obtained under the calcination condition of 450 °C for 6 h achieved a high specific capacitance of 1093 F g⁻¹. The electrode also exhibited high cycle stability for 5000 cycles. [ABSTRACT FROM AUTHOR]
