Abstract: Multi-functional additives containing at least one solid electrolyte interface (SEI) forming group and at least one SEI modifying group are advantageously employed in electrolyte compositions for electrochemical devices. The SEI forming group may comprise an organic carbonate moiety and the SEI modifying group may comprise a heteroatom functional group such as a sulfur containing organic moiety. The electrochemical devices include lithium ion batteries.
