HOST MATERIAL FOR STABILIZING LITHIUM METAL ELECTRODE, AND FABRICATING METHOD AND APPLICATIONS OF SAME
The invention relates to a host material for stabilizing a Li metal electrode, fabricating methods and applications of the same. The host material includes crumpled graphene balls operably defining a scaffold having volumes and voids inside and in between the crumpled graphene balls so as to allow uniform and stable Li deposition/dissolution inside and in between the crumpled graphene balls without electrode volume fluctuations or with sufficiently small electrode volume fluctuations. The crumpled paper ball-like structures of graphene particles can readily assemble to yield the scaffold with scalable Li loading up to 10 mAh cm-2 within tolerable volume fluctuations. High Coulombic efficiency of 97.5% over 750 cycles (1500 hours) is achieved. Plating/stripping Li up to 12 mAh cm-2 on the crumpled graphene scaffold does not experience dendrite growth.
