Method and device for forming three-dimensional separator structure, and method and device for calculating shape parameters of three-dimensional separator structure formed thereby

A device for forming a three-dimensional separator structure, the device comprising:

• a processor that determines whether a coating layer is necessary, whether a lamination simulation is necessary, and whether a swelling simulation is necessary based on design parameters and machine parameters;
• a separator former that determines a size of a domain and voxels based on the design parameters and uses a polyethylene separator weaving algorithm or a polypropylene separator weaving algorithm based on components of the separator structure and whether the separator structure is multi-layered to form a separator within the domain;
• a coating layer former that generates ceramic particles and a binder within the domain using the design parameters, and laminating the ceramic particles and the binder on the separator to form the coating layer;
• a lamination simulator that simulates rolling of the separator using the machine parameters and corrects a deformation error of the rolled separator to simulate lamination;
• and
• a swelling simulator that simulates expansion of the coating layer by using a swelling factor and the machine parameters and corrects a deformation error of the expanded coating layer to simulate swelling.
