Abstract

The invention belongs to the technical field of atomic layer deposition, and discloses an atomic layer deposition device and a deposition method suitable for powder samples. The atomic layer deposition device is provided with: a two-stage heatable main cavity; a two-stage heatable main cavity The outside of the chamber is connected with a mechanical rotating shaft and a vibrator driven by a motor or other means, and a flexible heatable gas pipeline is fixed at both ends of each stage of the two-stage heatable main chamber; The pipeline is externally connected with a pneumatic valve and a powder filter; the powder filter is connected with a heatable gas pipeline. The hourglass type atomic layer deposition equipment disclosed by the invention is suitable for experimental research and industrial-grade powder sample preparation. From the perspective of technology and equipment, it breaks through the efficiency and cost limitations of atomic layer deposition technology, and can realize a single milligram to ton level lithium battery. , Fuel cells, catalysts and other powder uniform coating.

Description

technical field [0001] The invention belongs to the technical field of atomic layer deposition, and in particular relates to an atomic layer deposition device and a deposition method suitable for powder samples. Background technique [0002] At present, powder coated coatings have been applied in energy fields such as lithium batteries, fuel cells, and catalysts. The surface coating modification of powders through ALD technology can improve their cycle and storage performance and prolong the service life of their products. [0003] When the traditional ALD equipment coats the powder, the first reaction chamber is always in the pumping state. After entering the chamber, the precursor is extracted before being adsorbed and saturated on the powder surface. It is suitable for coating a trace amount of powder on the surface, but The source of precursor is wasted, and the coverage rate is low. [0004] For the existing fluidized bed reaction chamber powder ALD equipment, the powd...
