[PROBLEMS] To provide a method for producing a LiCoO 2 sintered compact which can stably produce a high density sintered compact. [Solution] The CIP & Sintering method, which has a molding step and a sintering step in accordance with a cold hydrostatic pressing method, is adopted as a method for producing a LiCoO 2 sintered compact according to an embodiment of the present invention. Molding pressure is 1000 kg / cm <2> or more, sintering temperature is 1050 degreeC or more and 1120 degrees C or less, and sintering time shall be 2 hours or more. This makes it possible to stably produce a sintered body LiCoO 2 having an average particle size of less than a specific resistance of less than 90% and 20㎛ relative density and 3 KΩ? ㎝ 50㎛. |
