POSITIVE ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY |
摘要 |
A positive electrode material which can achieve high output, high energy density, and/or a long cycle life required for on-vehicle applications is discussed. The positive electrode material is used to produce a positive electrode of a lithium secondary battery, the positive electrode material being a composite lithium material that includes a first lithium compound and a second lithium compound. For instance, the first lithium compound is in the form of particles and comprises at least one compound selected from a layered lithium compound and a spinel-type lithium compound. Preferably, the second lithium compound comprises at least one compound selected from a lithium-containing phosphate compound and a lithium-containing silicate compound. An amorphous carbon material layer and/or graphene-structured carbon material layer is present on the entire surface of the first lithium compound and the second lithium compound. The second lithium compound forms a thin-film layer on part or the entirety of the carbon material layer present on the surface of the first lithium compound particles. |
