METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY

An object of the present invention is to provide a method for producing a cathode active material, which enables stable/consistent production of a cathode active material that can improve characteristics (e.g., capacity and durability) of a lithium secondary battery compared with conventional cathode active materials. [0002] The present invention relates to a method for producing a cathode active material for a lithium secondary battery characterized by including (1) a forming step of forming a sheet-form compact containing, as raw substances, a lithium compound serving as a first ingredient, a compound of a transition metal other than lithium serving as a second ingredient, and at least one of boron oxide and vanadium oxide serving as a third ingredient; and (2) a firing step of firing the compact at 700 to 1,300°C.
