摘要：
A method of increasing the amount of alkali metal that is available during charge/discharge of an electrochemical cell that employs carbon based intercalation anodes is provided. The method comprises of prealkaliation of the carbon anode. By subjecting the anode carbon to the prealkaliation process prior to packaging the electrochemical cell, substantially all the alkali metal (e.g., lithium) which is originally present in the cathode will be available for migration between the anode and cathode during charge/discharge.
