Itaconic Anhydride as a Novel Bio-Derived Solid Electrolyte Interphase Forming Additive for Lithium-Ion Batteries.

ABSTRACT: In this work, itaconic anhydride (ITC) is introduced as a novel bio-derived additive for lithium-ion batteries. Its ability to create a stable solid electrolyte interphase (SEI) is evaluated in graphite electrodes and compared to vinylene carbonate (VC). The findings show that electrolytes consisting of 1 M lithium bis(trifluoromethanesulfonyl)imide in propylene carbonate and containing ITC and VC additives display similar physicochemical properties. The ability of ITC to form an effective SEI is demonstrated by reversible lithium intercalation during galvanostatic cycling and further corroborated by in situ Raman spectroscopy. Moreover, graphite and lithium iron phosphate (LFP) half-cells display similar electrochemical performance in terms of rate capability and capacity retention along
