Abstract

Lithium-Ion Batteries Lithium bis(phosphorodifluoridate) triethylammonium ethenesulfonate (LiPENS), a molecular-engineered salt-type multifunctional additive, leverages the distinct functionalities of phosphorous, nitrogen, and sulfur-containing motifs to construct protective interfacial layers on electrodes in lithium-ion batteries. The thermally and electrochemically reinforced inorganic-rich interfaces markedly improve battery performance at high temperatures, establishing LiPENS as a promising additive for high-energy applications such as electric vehicles.
