Firstly, cobalt hydroxide nanowires network were grown on nitrogen doped microwave exfoliated graphite oxide OsJMEG). The specific capacitance can reach 610 F/g. Asymmetric pseudocapacitor devices were fabricated with Co(OH)2^IMEG as the positive electrode and polypyrrole(PPy)/rG-0 as the negative e...
