FLUORINATED ARYLBORON OXALATE AS ANION RECEPTORS AND ADDITIVES FOR NON-AQUEOUS BATTERY ELECTROLYTES

摘要

The present invention relates to electrochemical storage devices containing a non-aqueous lithium based electrolyte with high ionic conductivity, low impedance, and high thermal stability. More particularly, this invention relates to the design, synthesis and application of novel fluorinated arylboron oxalate based compounds which act as anion receptors and/or additives for non-aqueous batteries. When used as an anion receptor for non-aqueous battery electrolytes, the fluorinated arylboron oxalate enhances conductivity, lithium ion transference number and Solid Electrolyte Interface (SEI) formation capability during the formation cycling.
