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.
