ELECTROLYTE-COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES, ALL-SOLID-STATE BATTERY, AND PRODUCTION METHOD FOR ELECTROLYTE-COATED POSITIVE ELECTRODE ACTIVE MATERIAL PARTICLES

摘要

The main purpose of this invention is to provide electrolyte-coated positive electrode active material particles that are capable of increasing the discharge capacitance of an all-solid-state battery and of increasing battery efficiency. Said purpose is achieved in this invention by providing electrolyte-coated positive electrode active material particles characterized by having: positive electrode active material particles; and a sulfide solid electrolyte layer formed on the surface of the positive electrode active material particles.
