Aza crown ether compounds as anion receptors

摘要

A family of aza-ether based compounds including linear, multi- branched and aza-crown ethers is provided. When added to non-aqueous battery electrolytes, the new family of aza-ether based compounds acts as neutral receptors to complex the anion moiety of the electrolyte salt thereby increasing the conductivity and the transference number of LI. sup.+ ion in alkali metal batteries.
