Abstract
A simple method is disclosed for preparing LiPF.sub.6 based electrolytes for use in lithium non-aqueous batteries. LiPF.sub.6 is synthesized in a mixture of solvents employed in the electrolyte itself. Using the invention method, residual reactants and by-products of the reaction are easily removed to a required level for practical battery applications while the LiPF.sub.6 remains in solution. The method is suitable for preparing electrolytes for lithium ion batteries wherein solvents such as diethylcarbonate, ethylene carbonate, and propylene carbonate are employed.
