This invention relates to the field of battery technology, and more particularly to a method for improving the air stability of sulfide solid electrolytes. The method includes the following steps: mixing the sulfide solid electrolyte with a solvent to form a slurry one; mixing a thiol with a solvent to form a slurry two; simultaneously spraying slurry one and slurry two into the center of a mixing device equipped with a drying device, and drying them under the drying device, thereby improving the air stability of the sulfide solid electrolyte. This invention, by spraying the sulfide solid electrolyte and thiol, causes them to collide under a certain airflow, thereby allowing the thiol's mercapto groups to coordinate with metal cations or exposed sulfur vacancies on the surface of the sulfide solid electrolyte, forming stable thiols or complexes, thus achieving the effect of particle coating or partial coating of the sulfide solid electrolyte.

The application discloses a double-cone rotary fluidized bed ALD fluidized reactor and a powder particle coating method thereof. The reactor comprises a fluidized chamber, a deposition tank, a rotating mechanism, gas guide pipes and a vacuum pump. The upper and lower ends of the fluidized chamber are closed. The outer side of the fluidized chamber is symmetrically connected with two gas guide pipes. One of the two gas guide pipes is connected with a fluidizing gas supply system and is used for conveying fluidizing gas containing precursor reaction gas into the fluidized chamber. The other gas guide pipe is sequentially connected with a tail gas detection system and the vacuum pump. The two gas guide pipes are controlled by the rotating mechanism and are used for periodically overturning the reactor according to a overturning period. After each overturning of the reactor, the powder with a large particle diameter is more quickly settled into the deposition tank than the powder with a small particle diameter. The powder particles settled into the deposition tank stop or sharply reduce the opportunity of atomic layer deposition reaction, and the powder particles not settled into the deposition tank are suspended in the fluidizing gas and continue to react with the precursor reaction gas to form a single-layer coating.
