A method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas. The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.

Disclosed is an inactive-state determining method of an oxygen sensor, including the steps of determining whether the oxygen sensor is in a condition where the oxygen sensor can be activated. It is determined whether an engine is in an idle state. A predetermined time is counted. It is determined whether electromotive force from the oxygen sensor is below a slice level even after the predetermined time is passed. An amount of fuel injected is increased by 20%. It is determined whether the electromotive force of the oxygen sensor is below the slice level even when the increased fuel is injected.
