文摘The reasonable design of electrode materials is crucial for tuning the electrochemical performances of advanced energy storage systems.Co–Ni–Se nanosheets uniformly growing on a butterfly-wing-derived carbon framework(Co–Ni–Se/BWCF)with strong anchoring are devised and prepared by a microwave treatment–ion exchange–chemical etching–hydrothermal selenization technique.Benefiting from its multi-components and unique structure,Co–Ni–Se/BWCF-160 exhibits excellent supercapacitor and sodium storage performances as self-supporting electrodes.
