Title:
COMPOSITE PARTICLE, SOLID BATTERY ELECTRODE, AND METHOD FOR MANUFACTURING COMPOSITE PARTICLE
Document Type and Number:
Japanese Patent JP2015062186
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide: a composite particle which can give a high output when used in a solid battery; a solid battery electrode arranged by use thereof; and a method for manufacturing such a composite particle.SOLUTION: A composite particle comprises: a complex of active material particles; and an oxide solid electrolyte between the active material particles. In the composite particle, no sulfide solid electrolyte is included. A solid battery electrode comprises: the composite particles; and a sulfide solid electrolyte. A method for manufacturing the composite particles comprises a spray step for forming particles from an organic solvent solution including active material particles and an oxide solid electrolyte precursor in a rolling fluidized bed granulation device. During the spray step, the intake-air temperature in the rolling fluidized bed granulation device is adjusted to be a temperature at which surfaces of the active material particles can be put in a wet condition when the surfaces of the active material particles are coated with the organic solvent solution of the oxide solid electrolyte precursor.
