Annulated tetra-substituted hydroquinone ether-based redox shuttle additives for lithium-ion batteries
An electrolyte for a lithium-ion electrochemical cell comprises a non-aqueous solution of a lithium salt and a redox shuttle compound, wherein the redox shuttle compound comprises —OR groups at carbons 1 and 4 of a benzene ring; a first hydrocarbon ring fused to carbons 2 and 3 of the benzene ring; and a second hydrocarbon ring fused to the carbons 5 and 6 of the benzene ring, wherein either (i) the first and second hydrocarbon rings together with the benzene ring constitute two fused benzobicyclo[2.2.2]octane ring systems sharing a common benzo core group; or (ii) the first and second hydrocarbon rings together with the benzene ring constitute two fused benzobicyclo[2.2.1]heptane ring systems sharing a common benzo core group.
