In this study, reduced crumpled graphene ball (rCGB)-polymer hybrid protective layer is used for physically suppression of dendrite growth in Lithium metal battery (LMB). The protective layer is consisted of PVdf-HFP polymer where rCGB is uniformly dispersed. rCGB is synthesized by aerosol process and heat treatment in N2 atmosphere. rCGB is analyzed by SEM, TEM and FTIR spectroscopy to understand its morphology and functional groups. With improved mechanical strength and ion conductivity, the hybrid protective layer electrode exhibits better electrochemical performance (coulombic efficiency, cycle stability) than that of controls (bare Cu, and PVdF-HFP polymer-coated electrode). |
