    摘要: The invention provides a cathode for a lithium secondary battery including lithiated nickel dioxide with a large discharge capacity as an active material and having a high density so that a larger amount of the active material can be charged in a battery container with a limited volume, a production method for the same and a lithium secondary battery utilizing the cathode. The cathode for a lithium secondary battery includes lithiated nickel dioxide as an active material, and the lithiated nickel dioxide is produced by firing a mixture of a lithium compound and a nickel compound at a temperature ranging between 350°C and 800°C. The supernatant obtained by dispersing 5 g of the lithiated nickel dioxide in 100 cm³ of water in a glass vessel for 5 minutes and allowing the resultant solution to stand for 30 seconds has pH of 12.00 or less. The production method includes the steps of obtaining the lithiated nickel dioxide as above and treating or milling the lithiated nickel dioxide in an atmosphere including carbon dioxide.
