Electrochemical Properties of a Mixed Boric Ester as a Novel Electrolyte Solvent

A blend of several boric esters was adopted as a novel electrolyte solvent exhibiting the high oxidation potential and favorable lithium ion conductivity. Spontaneous transesterification between boric esters takes place resulting in a mixed boric ester. The electrochemical properties that the mixed ester acquired seem to be descended from the properties of parent boric esters: thus B(OCH3)3 (1) or B(OCH2CH3)3 (2), and B(OCH2CH2CN)3 (3) were low viscous, and a good solvent for lithium salts respectively.
