Title:
DRY COATING AND SELF-SUPPORTING LAYERS WITH ALIGNED PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/214411
Kind Code:
A3
Abstract:
The invention relates to a method for the dry coating of surfaces of a carrier (4) and/or for producing self-supporting layers, in particular for use in lithium ion batteries with improved properties, the coating being carried out at least by means of a powder (P) which contains particles and is in the dry state, in particular with a solvent concentration of less than 1 wt%, and the particles are aligned in order to reduce the ionic resistance of the powder layer (P). The alignment of the particles also includes a fluidization of the powder.
