Abstract
A more efficient LiPFlithium-ion electrochemical system composed of a phosphate free, borate lithium salt electrolyte LiTPTB composed of LiBCFHin a ternary mixed organic solvent containing a 1:1:1 volume ratio of EC, DMC and EMC is provided. The borate salt of the LiTPTB electrolyte decomposes at temperatures above 110° C. and does not react with water and also has an oxidation potential of about 4.4 V versus lithium, making it suitable for use in high voltage lithium-ion cells and batteries. A 0.3 to 1.0 M molar concentration of LiTPTB composed of LiBCFHin a ternary mixed organic solvent containing a 1:1:1 volume ratio of EC, DMC and EMC is also provided.
