Lithium secondary battery and its method of manufacturing

摘要

A secondary battery is provided that comprises a positive electrode including a positive active material, a negative electrode including a negative active material; and a separator interposed between the positive electrode and the negative electrode; wherein at least one of the positive electrode, negative electrode and separator comprises a metal molybdate, wherein at least a portion of the metal molybdate is amorphous. Also provided is a method of manufacturing a secondary battery comprising a positive electrode including a positive active material, a negative electrode including a negative active material and a separator interposed between the positive electrode and the negative electrode, wherein at least one of the positive electrode, negative electrode and separator comprises synthesized lithium molybdate, the method comprising forming the synthesized lithium molybdate by: mixing a lithium precursor with a molybdium precursor to form a mixture; heating the mixture to form crude lithium molybdate; heating the crude lithium molybdate to form synthesized lithium molybdate; wherein at least a portion of the synthesized lithium molybdate is amorphous.
