Title: POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, METHOD FOR PRODUCING SAME AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Abstract:
Provided is a positive electrode active material for a lithium secondary battery, the positive electrode active material comprising: a compound capable of reversible lithium intercalation/deintercalation; and a coating layer positioned on at least one portion of the surface of the compound capable of reversible lithium intercalation/deintercalation. The compound capable of reversible lithium intercalation/deintercalation is doped with a metal M and F, wherein the metal M is at least one element selected from the group consisting of Mg, Ca, Ni, Ti, Al, Si, Sn, Mn, Cr, Fe and Zr. The coating layer comprises Li3PO4.
