Electrochemical cell structure and method of fabrication

摘要

One limitation to the realisation of mass produced electrochemical cells is a lack of high resolution patterning techniques providing accurate alignment. A method of fabricating a patterned structure on a polymer layer for the manufacture of an electrochemical cell is provided. The method comprises: depositing a polymer layer upon a substrate; and stamping the polymer layer to form an embossed polymer layer using an embossing tool, the embossing tool having a first array of adjacent cells, spaced from one another and extending from the stamping face of the embossing tool and thereby forming a second array of adjacent cells, spaced from one another and extending as cavities within the embossed polymer layer.

1. A method of forming a component of an electrochemical cell, comprising:
forming a first electrode on a substrate; forming a polymer layer on the first electrode; stamping the polymer layer to form a first embossed polymer layer using an embossing tool, the embossing tool having a pattern; removing the embossing tool from the polymer layer; and removing a part of the first embossed polymer layer to form a second embossed polymer layer, a part of the first electrode being exposed; and forming a metal oxide and a dye on an exposed electrode by an ink jet process, including depositing a metal oxide colloidal suspension and a dye solution into a cavity of the second embossed polymer layer by the ink jet process.
