Title:
DEVICE FOR PERFORMING IN-VACUO HEAT SEALING AND LAMINATION FOR BATTERY MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2024/101454
Kind Code:
A1
Abstract:
The present invention provides a manufacturing device that performs minimal-impact dearation during the laminating of sheet-form materials, thereby making it possible to laminate sheet-form materials in a high-quality manner to manufacture a high-performance lithium ion battery. This device for performing in-vacuo heat sealing and laminating in the manufacturing of lithium ion batteries, in which a positive-electrode sheet (11P) and a negative-electrode sheet (11N) provided with resin current collectors are individually surrounded by a frame body (13) and are sealed with a separator sheet interposed therebetween, comprises: inner regions (57 (57a-57d)) of heaters (51, 53) that join together the sheets, which face each other across the separator sheet, at a plurality of locations over the entire periphery between the respective frame bodies; a depressurizing device unit that suctions air between the sheets from between the plurality of joining locations between the frame bodies to reduce pressure; and an outer region (55) of a heater that joins and seals the entire periphery between the frame bodies from which air was suctioned between the sheets.
