Ce-Modified MnCo2O4 Flower-like Nanosheet Electrodes via PVP-Assisted Assembly for MnCo2O4//Carbon-Supported Iron Oxide Asymmetric Supercapacitors

{{output}}
Ce-modified MnCo2O4 flower-like nanosheet electrodes were prepared on nickel foam by a hydrothermal-calcination route and sequentially optimized with respect to reaction time, nominal Ce content, and PVP addition. Comparative SEM, XRD, XPS, and N2-sorption ana... ...
