Preparation and electrochemical performance analysis of cobalt based supercapacitor materials
Cobalt based materials have the advantages of low cost,wide natural distribution,and richer redox reac-tions,making them a research hotspot for supercapacitor electrode materials.This study prepared five different rati-os of active materials using cobalt chloride and sodium borohydride as raw materials,characterized the morphology of the materials,and conducted electrochemical performance testing in a three electrode system.The research re-sults showed that at a current density of 1 A/g,the specific capacitance of the cobalt compound with n(Co2+)∶n(NaBH4)=1∶2 could reach 757 F/g.
