Abstract

The invention discloses a dry powder thermal compounding transferring and coating method and system. The system comprises a powder transferring apparatus and a thermal curing apparatus, wherein a current collector partially coats the powder transferring apparatus; the powder transferring apparatus feeds mixture powder to the coating inlet of the current collector and the powder transferring apparatus; the mixture powder at least comprises a positive electrode active material or a negative electrode active material, and a viscous material; and the thermal curing apparatus is used for heating the thermal viscous material to enable the viscous material and other materials in the mixture powder to be cured into an integrated body so as to form a mixture layer on the current collector. By virtue of the dry powder thermal compounding transferring and coating method and system, the mixture powder does not scatter, so that the formed mixture layer has the advantage of uniform thickness; and meanwhile, any solvent is not needed, so that environmental pollution caused by the solvent can be avoided, the solvent is saved and cost of drying the solvent can be reduced.

Description

technical field [0001] The invention relates to a dry powder thermal composite transfer coating method and system, in particular to a dry powder thermal composite transfer coating method and system for lithium battery electrodes. Background technique [0002] The coating of the existing lithium ion electrodes is wet coating. This wet coating is to mix the active material of the lithium ion battery with the corresponding organic solvent, and then transfer coating or extrusion coating. The method of cloth is applied to the substrate. In this coating method, after coating, a long baking device is required to dry and bake the coated electrode, so as to remove the organic solvent and water in the electrode active material. If the baked organic solvent is directly discharged into the air without being recycled, it will cause air pollution. If it is recycled, it will increase the user's fixed asset investment and operating costs. [0003] In order to solve the above-mentioned pro...
