    Abstract: A method of forming an electrolyte solution involves combining ammonium tetrafluoroborate and a quaternary ammonium halide in a liquid solvent to form a quaternary ammonium tetrafluoroborate and an ammonium halide. The ammonium halide precipitate is removed from the solvent to form an electrolyte solution. The reactants can be added step-wise to the solvent, and the method can include using a stoichiometric excess of the ammonium tetrafluoroborate to form a substantially halide ion-free electrolyte solution. Filtration can be done at low temperatures to reduce the amount of excess bromide in the resulting electrolyte.

    Abstract: A method for pre-doping a lithium ion capacitor, including: compressing a lithium ion capacitor of the formula: C/S/A/S/C/S/A/S/C, where: /A/ is an anode coated on both sides with an anode carbon layer, and each anode carbon layer is further coated with lithium composite powder (LCP) layer; C/ is a cathode coated on one side with a layer of an cathode carbon mixture; and S is a separator; and a non-aqueous electrolyte; and conditioning the resulting compressed lithium ion capacitor, for example, at a rate of from C/20 to 4C, and the conditioning redistributes the impregnated lithium as lithium ions in the anode carbon structure. Also disclosed is an carbon coated anode having lithium composite powder (LCP) layer compressed on the carbon coated anode.
