Tertiary butyl hydroquinone as a novel additive for SEI film formation in lithium-ion batteries

Abstract

Electrolyte additives play a key role in the performance of lithium ion batteries. In this study, we reported tertiary butyl hydroquinone (TBHQ) as a new electrolyte additive with a promising prospect. It largely improved the electrochemical performance of the graphite electrode such as cyclic stability and reversible capacity. The improvement was benefited from the effective formation of a stable and compact thin solid–electrolyte-interface (SEI) film to reduce the resistance. Thus, this study demonstrated a promising electrolyte additive for improving lithium-ion battery performance.
