Zn-doped FeOOH-polypyrrole electrodes for supercapacitors
Abstract
The problem of poor cyclic stability of FeOOH anodes for supercapacitors was addressed by Zn-doping. Zn-doped FeOOH materials exhibited significant improvement in capacitance retention during cycling. Further improvement in capacitance retention and capacitive properties at low absolute values of negative potentials was achieved in composites containing Zn-doped FeOOH and polypyrrole-coated carbon nanotubes. Another important finding was a …
