Abstract:
With the fast-growing energy demand in consumer electronic devices and electric vehicles, there has been great interest worldwide in the development of advanced electrode materials for high-performance energy storage devices. An emerging new concept is to grow electroactive nanostructures on conductive substrates to be directly used as integrated electrodes for supercapacitors.
Growing nanosheets for supercapacitor electrodes
Germany | Posted on December 12th, 2012Now, in a new publication, Professor X. W. Lou and co-workers report a simple template-free solution method combined with a post annealing treatment to grow interconnected mesoporous NiCo2O4 nanosheets on various conductive substrates with robust adhesion as a binder and conductive agent-free electrode for supercapacitors. Such integrated electrodes exhibit ultrahigh specific capacitance and excellent cycling stability even at a high charge/discharge current density.
