EXTRUSION COATING APPARATUS AND BATTERY PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/231000
Kind Code:
A1
Abstract:
Embodiments of the present application provide an extrusion coating apparatus and a battery production system. The extrusion coating apparatus comprises: a first die and a second die that are snap-connected to each other; a flow channel formed between the first die and the second die, the flow channel comprising a material inlet and a material outlet; and a gasket, which is provided between the first die and the second die, and disposed at both sides of the flow channel along a direction from the material inlet to the material outlet. In a production process, the specifications of the gasket can be adjusted according to speed distribution changes at the material outlet, thus adjusting the dimensions of the flow channel and changing the flow channel, and controlling extrusion speed distribution, so as to be used for slurries of different viscosities, and meet consistency requirements for slurry extrusion speed.
