Two-dimensional layered cobalt-based coordination polymer for supercapacitive performance

Abstract

Coordination Polymers (CPs) are an intriguing choice and have lately been acknowledged as attractive materials to be utilized for supercapacitor application. In this report, we prepared a layered Co-CP by utilizing a slow diffusion technique. Further, Co-CP was well characterized using SC XRD, displayed excellent pseudocapacitor behavior with excellent specific capacitance (Cs) around 1092 F g-1 at 1.5 A g-1 , and sustained its cyclic retention at 98% over 6500 GCD cycles. The electrolytic study was performed utilizing three different electrolytes (NaOH, KOH, LiOH), and further evaluated the electrochemical performance of the Co-CP in different electrolytic concentrations (3M, 5M, 7M of NaOH).
