Bifunctional Electrolyte Additive Enabling Simultaneous Interphase Formation on Both Electrodes in High-Energy Lithium-Ion Batteries.

ABSTRACT: The development of next-generation Lithium-ion batteries (LIBs) to meet the demands of advancing technology and energy storage requires focus on the formation of effective interphases on both the positive and negative electrodes. Different promising approaches to facilitate effective interphase formation are already known Out of these, the incorporation of film-forming electrolyte additives is a straight-forward strategy to achieve this goal. In the presented study, a bifunctional electrolyte additive, (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl thiophene-3-carboxylate composed of two functional motifs, vinylene carbonate (VC) and thiophene, is reported. Upon LIB operation, the additive undergoes in situ splitting, forming a VC-assisted solid electrolyte interphase (SEI) and a polythiophene-bas
