Blanket-like Co(OH)2/CoOOH/Co3O4/Cu(OH)2 composites on Cu foam for hybrid supercapacitor

Novel blanket-like Co(OH)2/CoOOH/Co3O4/Cu(OH)2 composites on Cu foam are prepared through the electrochemical conversion of the precursors synthesized using hydrothermal method, named as CV sample. After the electrochemical conversion, flatbread-like precursors changes to blanket-like Co(OH)2/CoOOH/...
