Problems solved by technology

[0002] Due to the large amount of wet coating on lithium battery pole pieces and the difficulty in drying, the traditional process only uses an oven to heat the material by means of hot air convection, and the efficiency of heat energy permeating and conducting from the surface of the substrate to the coating material is low. During the drying process, the coating is heated unevenly, resulting in dry surface and easy cracks
Ultimately restricts the drying effect and coating speed

Description

Technical field [0001] The present invention relates to the field of coating technology, specifically a lithium battery electrode coating heating process and equipment. Background [0002] Due to the large amount of wet coating of lithium battery pole sheets, drying is difficult, the traditional process, only the use of the oven using hot air convection method to heat the material, the efficiency of thermal energy from the surface of the substrate permeation to the coating material is low, so in the drying process the coating heat is uneven, resulting in surface drying, easy to produce cracks. The drying effect and coating speed are ultimately restricted. Contents of the Invention [0003] Object of the present invention is to provide a lithium battery pole plate coating heating process and apparatus to solve the problems raised in the above background technique. [0004] A technical solution proposed in the first aspect of the present invention is: a lithium battery polar plat...
