SOLID ELECTROLYTE STRUCTURE FOR ALL-SOLID-STATE BATTERY, ALL-SOLID-STATE BATTERY, AND THEIR PRODUCTION METHODS

摘要

Disclosed is a solid electrolyte structure (1) for all-solid-state batteries, which comprises a plate-like dense body (2) composed of a ceramic containing a solid electrolyte, and a porous layer (3) composed of a ceramic containing a solid electrolyte which is the same as or different from that of the dense body (2) and integrally formed on at least one surface of the dense body (2) by being fired thereon. This solid electrolyte structure (1) for all-solid-state batteries enables to reduce connection resistance at the connection interface with an electrode.
