Title:
リチウム二次電池正極活物質用リチウム遷移金属複合酸化物、その製造方法およびそれを用いたリチウム二次電池
Document Type and Number:
Japanese Patent JP4656349
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a simple manufacturing method of lithium transition metal oxide compound which can constitute a lithium secondary battery with a good cycle characteristics in the case of use for a positive electrode active material, and of lithium transition metal oxide compound. SOLUTION: Lithium transition metal oxide compound for positive electrode active material is constructed so that the rate of mean particle diameter of secondary particles against that of primary particles be not less than 1 not more than 5, that is, the number of the primary particles constituting one secondary particle be lessened. Further, the lithium transition metal oxide compound is manufactured by a method including a process of recrystallization treatment for removing crystal distortion of the primary particle crystal.
