Title: Electrolyte for high voltage lithium-ion batteries

Abstract

An electrolyte, electrochemical device, battery, capacitor, and/or the like include a salt; and a fluorinated organosulfate compound represented by Formula I: wherein, R1 is H, OR3, alkyl, alkenyl, alkynyl, aralkyl, or silyl; R2 is H, OR3, alkyl, alkenyl, alkynyl, aralkyl, or silyl; and R3 is H, alkyl, alkenyl, alkynyl, aryl, heterocyclyl, heteroaryl, or siloxy; or where R1 and R2 join together to form a cyclic compound incorporating the —O—S(O)2—O— group; wherein at least one R1 and R2 is fluorinated.
