Abstract
A method of making a secondary, lithium-ion cell having a carbon anode including the step of deactivating the carbon anode by heating the carbon in the presence of oxygen for a time sufficient and at a temperature sufficient to selectively oxidize undesirable, highly reactive carbon atoms therefrom prior to assembling the cell, and a stochiometrically balanced cell made from such deactivated carbon.
