Abstract
A method of fabricating a battery electrode includes forming a mixture including an electrode material and a binder; forming an electrode blank from the mixture; heating the electrode blank at a predetermined temperature for a predetermined time to form an annealed electrode blank; and laminating the annealed electrode blank to a current collector. The current collector may include a conductive carbon coating. In such event, the method may further include heating the current collector at a selected temperature for a selected time prior to laminating the annealed electrode blank to the current collector.
