Performance study of bimetallic Mn-Zn porous flower-like nanosheets as supercapacitor positive electrode materials
Source abstract
Abstract
As environmental and carbon emission issues become increasingly severe, electrochemical energy storage systems have gained attention. Compared to traditional supercapacitors, zinc-ion hybrid capacitors (ZIHCs) are not only environmentally friendly but also cost-effective. MnO 2, with its low cost, eco-friendliness, high theoretical capacity, and stable crystal structure, is considered a promising positive electrode material. In this study, the morphology of MnO 2 was optimized using electrodeposition. During cycling, zinc ions reversibly intercalate and extract from MnO 2, forming a cactus-like nanoflower structure. This structure is loose and porous, providing ample reaction space for active materials. The assembled device exhibits excellent performance in both energy density (85.68 Wh kg −1) and stability (91.60 %).
