Abstract

The performance of a lithium metal anode was studied in a poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP) gel electrolyte. By using the PVdF-HFP gel electrolyte, we obtained a higher coulombic efficiency (ca. 85%) and a more uniform morphology of the lithium metal anode than those obtained with the propylene carbonate liquid or the poly(ethylene oxide) gel system. Additionally, the CO₂ addition to the PVdF-HFP gel system improved both the uniformity in morphology of the lithium anode and the coulombic efficiency further to ca. 95%.
