POSITIVE ELECTRODE BODY FOR NONAQUEOUS ELECTROLYTE BATTERY, METHOD FOR PRODUCING SAME, AND NONAQUEOUS ELECTROLYTE BATTERY

摘要

Provided is a positive-electrode body for a nonaqueous-electrolyte battery in which formation of high-resistance layers at the contact interfaces between positive-electrode active-material particles and solid-electrolyte particles is suppressed so that an increase in the interface resistance is suppressed. A positive-electrode body 1 for a nonaqueous-electrolyte battery according to the present invention includes a mixture of sulfide-solid-electrolyte particles 11 and covered positive-electrode active-material particles 10 in which surfaces of positive-electrode active-material particles 10a are covered with cover layers 10b having Li-ion conductivity. The cover layers 10b are formed of an amorphous oxide having oxygen deficiency. The cover layers 10b have oxygen deficiency and, as a result, Li-ion conductivity and electron conductivity that are sufficient for charge and discharge of the battery can be stably ensured in the cover layers 10b.
