In this study we report for the first time the application of an emerging bio-based solvent derived from lactic acid, namely 5-methyl-1,3-dioxolan-4-one (LA-H,H), as an electrolyte component for lithium-ion batteries (LIBs). Electrolyte formulations consisting of this new bio-solvent and immide-based conducting salts (i.e., lithium bis(trifluoromethanesulfonyl)immide, LiTFSI, and lithium bis(fluorosulfonyl)immide, LiFSI) together with the additive vinylene carbonate (VC) were prepared and thoroughly evaluated.
