Title:
COATING EDGE CONTROL
Document Type and Number:
WIPO Patent Application WO2002101854
Kind Code:
A3
Abstract:
A methods of coating certain materials onto a substrate, including coating a coating material and an edge material onto the substrate in a manner which may provide an improved thickness profile of the overall coating, by using the edge material to augment the thickness of the coating material edge, or by improving the coating material edge by using the edge material to affect the shape of the coating material edge, the products being useful, for example, in electrochemical cells. This coating method permits to control edge thickness and profile of coating.
