摘要：
The disclosure relates to an electrode active material including: (a) first particulate of a metal (or metalloid) oxide alloyable with lithium; and (b) second particulate of an oxide containing lithium and the same metal (or metalloid) as that of the metal (or metalloid) oxide, and to a secondary battery including the electrode active material. When the electrode active material is used as an anode active material, reduced amounts of an irreversible phase such as a lithium oxide or a lithium metal oxide are produced during initial charge-discharge of a battery since lithium is already contained in the second particulate before the initial charge-discharge, and thus a dead volume on the side of the cathode can be minimized and a high-capacity battery can be fabricated.
