Method for manufacturing film battery e.g. lithium ion battery mounted in vehicle, involves forming frame by casting around edge region of film stack, and opening casting tool after removal of a frame which is provided film stack

摘要

The method involves providing film stack (11). The film stack is loaded in a casting tool. The casting tool is closed. The frame is formed by casting around the edge region of the film stack. The casting tool is opened after removal of a frame which is provided film stack. The polarity of connection lugs (12) of film stack is identical to each other. The superposed connection lugs are crimped. The flanged connection lugs are welded. An independent claim is included for lithium ion battery element.
