1. A composite electrode for a supercapacitor, the electrode comprising:
a composite CNT-ZIF structure comprising a conductive network of carbon nanotubes (CNT) and a zeolitic imidazole framework (ZIF) coating covering the conductive network, the ZIF coating providing high ion diffusivity; and
a layer of molybdenum disulfide (MoS2) structures disposed on the composite CNT-ZIF structure, the MoS2 structures comprising pores that provide diffusion paths for ions to and/or from the ZIF coating and/or the conductive network of CNT, wherein the MoS2 structures have a flower-like (fMoS2) morphology.
