1. A method of forming an electrode material for use in a battery, the method comprising:
calcining electric arc furnace flue dust so as to recover a metal oxide therefrom, the calcining being at a temperature of 200° C. to 1500° C. for a period of one hour to twenty-four hours, the metal oxide having a purity of between 20% to 99.99%; and
forming the electrode material for use in the battery from the calcined electric arc furnace flue dust without applying any mechanical treatment.
