発明の名称 (英語) COMPOSITE POSITIVE ELECTRODE ACTIVE MATERIAL FOR ALL-SOLID-STATE SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, POSITIVE ELECTRODE, AND ALL-SOLID-STATE SECONDARY BATTERY
発明の概要(英語) This composite positive electrode active material for an all-solid-state secondary battery includes: a particulate positive electrode active material; and a sulfide-based solid electrolyte layer that covers the surface of the particulate positive electrode active material, wherein the composite positive electrode active material has an average roundness higher by 1.3 times than that of a positive electrode active material in the inner nucleus of the composite positive electrode active material.
従来技術、競合技術の概要(英語) BACKGROUND ART
The lithium secondary battery, high voltage, for high capacity, a mobile phone, digital camera, video camera, a notebook personal computer, as a power source of electric vehicles are widely used. Generally flows in the lithium secondary battery, as an electrolyte, electrolyte salt is dissolved in the non-aqueous solvent using a liquid electrolyte. Is a non-aqueous solvent, containing a large amount of flammable solvent so that, for ensuring safety is demanded. In order to ensure the safety, without the use of a non-aqueous solvent, a solid electrolyte formed from a material, a so-called solid electrolyte is used and the all-solid lithium secondary battery has been proposed. To the positive electrode of this battery, the positive electrode active material, conductive material, the various components of the electrolyte or the like is included. For example, Japanese Patent Laid-Open Patent Publication 2007-149438 (Patent Document 1) in Fig. 1, a plurality of particulate positive electrode active material layer of the solid electrolyte for the positive electrode includes the complex has been proposed.
