Document Type and Number:
Japanese Patent JPH1145718
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode which has a high-rate characteristic by giving high capacity to a battery, by providing Sa/Sc of a lithium compound oxide within a specific range, when it is defined that specific surface area Sa of the lithium compound oxide in a BET method, the grain size is r, the particle size distribution is f(r), density is d, and Sc is a value derived from a specific relation. SOLUTION: Lithium compound oxide preferably satisfies 1.5<=Sa/Sc<=10, and more preferably satisfies 2<=Sa/Sc<=8. In addition, the lithium compound oxide is preferably Lix Niy Mz O2 (where, 0.8
