Abstract

Synthesis, analysis, and purification of new lithium salts for lithium batteries, lithium bis[tetrafluoro-1,2-benzenediolato(2-)-O,O']borate and Lithium bis[2,3-naphthalenediolato(2-)-O,O']borate described, and the results of electrochemical studies of these salts and of lithium bis[3-fluoro-1,2-benzenediolato(2-)-O,O']borate in propylene carbonate are reported. The effect of the electron-withdrawing substituent fluorine results in an increase of the electrochemical window by 0.1 V/fluorine per one chelate Ligand. The slope, which can be calculated from the linear correlation of the highest occupied molecular orbital energies with anodic oxidation potentials is -3.0 eV/V, a value equal to that known for aryl berates and fluoroaryl berates.
