Zn-Co double metal sulfide as high energy density Faradic electrode material has great potential for supercapacitors,but its poor transmission efficiency of electron and ions hinders its electrochemical response.Herein,the ZnCo2(CO3)1.5(OH)3@ZCS microflower hybrid arrays consisting of the thin nanolayer petals are anchored on three-dimensional graphene(ZnCo2(CO3)1.5(OH)3@ZCS/3DG)via a simple and feasible hydrothermal method and additional ion-exchange process.
