ALL-SOLID STATE SECONDARY BATTERY AND PRODUCTION METHOD FOR SAME

摘要

Disclosed is an all-solid state secondary battery and production method for same that uses an electrode material, wherein a carbon material has been added as conductor to an electrode active material, and for which the conductor transfers sufficient electron conductivity to the electrode layer even when the electrode layer and a solid electrolyte layer are sintered. The all-solid state secondary battery (10) comprises a positive electrode layer (11), a solid electrolyte layer (13) which includes an oxide-based solid electrolyte layer, and a negative electrode layer (12). At least one of either the positive electrode layer (11) or the negative electrode layer (12) and the solid electrolyte layer (13) are bonded by sintering; at least one of either the positive electrode layer (11) or the negative electrode layer (12) includes an electrode active material and a conductor that includes a carbon material; and the conductor includes carbon material with a specific surface area of 1000m2/g max.
