Synthesis method of lithium cobalt oxide (LiCoO₂) for non-aqueous lithium secondary battery, production of positive electrode and lithium secondary battery using same

摘要

The present invention synthesizes a stable active material even if the lithium intercalation / deintercalation reaction is continued by varying the heat treatment conditions during the synthesis of lithium cobalt oxide (LiCoO ₂ ), and by mixing a conductive material and a binder in the active material to prepare an electrode The present invention relates to a method for synthesizing a lithium cobalt oxide (LiCoO ₂ ) for a non-aqueous lithium secondary battery that can be used as a positive electrode of a lithium secondary battery, and to manufacturing a positive electrode and a lithium secondary battery using the same.
