摘要： It is an object of the present invention to provide a cathode active material capable of reducing degradation in an operation voltage and capacity as compared conventionally when used for a lithium ion secondary battery, and a method for manufacturing the same. The cathode active material contains a composite oxide of lithium and a transition metal (s), wherein a reduction loss of TLC in the composite oxide is 20 to 60%. Also, the composite oxide has a particle diameter of 0.5 to 100 μm, and is preferably fluorinated. The method for manufacturing the cathode active material includes the step of fluorinating the cathode active material. The composite oxide has a particle diameter of 0.5 to 100 μm. The fluorinating step is to fluorinate the composite oxide in a reaction vessel under conditions where fluorine gas partial pressure is 1 to 200 kPa, a reaction time is 10 minutes to 10 days, and a reaction temperature is −10 to 200° C.
