One-step, simple and inexpensive successive ionic layer adsorption and reaction (SILAR) method has been used to synthesize porous network of zinc cobaltite (ZnCoO) in 2D form on stainless steel (SS) substrate. Porous structure of ZnCoO electrode enables electrochemical specific capacitance of 675Fg at 5mVs sweep rate with high rate capability and cycling performance of 69% over 2000 cycles. Furthermore, fabricated ZnCoO solid-state supercapacitor cell in symmetric mode using PVA-KOH gel electrolyte exhibited a specific capacitance of 69.65Fg with specific energy of 9.67Whkg and specific power of 1.45kWkg at a current density of 1.07Ag. The results clearly demonstrate the facile method for the synthesis of porous network of ZnCoO and make them promising electrode material for energy storage application.
