In situ growth of binder-free CoNi0.5-MOF/CC electrode for high-performance flexible solid-state supercapacitor application

We prepared an electrode by in situ growth of CoNi 0.5 -MOF on H 2 O 2 -pretreated carbon cloth without a binder, with high specific capacitance (1337.5 F g −1 at 1 A g −1 ) and excellent rate ability. An assembled flexible device has high energy density.
