発明の名称 (英語) LITHIUM COMPOSITE OXIDE, POSITIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERY, AND SECONDARY BATTERY NEW コモンズ
発明の概要(英語) The purpose of the present invention is to provide: a lithium composite oxide having a reversible capacity of approximately 250 mAh/g; a positive electrode active material for secondary batteries; and a secondary battery that includes the lithium composite oxide. The present invention relates to a lithium composite oxide having a spinel structure and characterized by having a chemical composition represented by general formula (1). General formula (1): Li1+zNiaMn2-yMbCuyO4-xFx [In general formula (1), 0
従来技術、競合技術の概要(英語) BACKGROUND ART
The lithium composite oxide, a lithium secondary battery used as a positive electrode active material. The lithium secondary battery, such as a portable telephone or notebook personal computer has been the size of the application has been put into practical use as a power source. And power storage applications such as automotive applications further medium, or large applied in a power source has been attempted. In this way with the expansion of the application, to improve the performance of the lithium secondary battery is an important problem.
Spinel-type lithium manganate and the Ni substituted compounds or a derivative thereof, a high potential, low cost, even for non-toxic, as electrode material for a lithium ion battery is an attractive material. Spinel-type lithium manganate is substituted with Ni performed various studies. For example, to Patent Document 1, using LNMO-type lithium composite oxide in order to improve the capacity of the battery, thereby reducing the amount of additive, the lithium composite oxide film of dense small voids were produced are described.
Non-Patent Document 1 is of the lithium composite oxide, the lower limit cutoff potential (vs. Li + / Li) as 3.5V, is used as the positive electrode active material is a theoretical capacity of, at 147mAh/g.
