Electrochemical device manufacturing
First Claim
1. A process for manufacturing of at least a part of an electrochemically active device comprising performing the following steps in sequence directly following each other:
- providing a prefabricated substrate (110) comprising an electrode receiving surface portion (111) having a substantially constant first wetting tension throughout said electrode receiving surface portion,providing a plurality of first electrodes (120) directly on said electrode receiving surface portion having a substantially constant first wetting tension of the prefabricated substrate, wherein the surfaces of said plurality of electrodes have a second wetting tension,leaving intermediate portions (130) of said electrode receiving surface portion (111) free from said electrodes,providing a printable electrolyte (140) having a first corresponding surface tension,arranging said printable electrolyte as a layer of electrolyte (140) directly on each one of said plurality of electrodes, wherein the electrolyte (140) is applied as a layer covering said plurality of first electrodes (120) and said intermediate portions (130), andawaiting a self-patterning of the electrolyte,whereinsaid first wetting tension of said substrate is lower than or equal to said first corresponding surface tension of said electrolyte, andsaid second wetting tension of said electrodes is higher than said first corresponding surface tension of said electrolyte,which provides the self-patterning of the electrolyte.

Abstract
A process for manufacturing an electrochemically active device comprising the steps of: —providing a substrate (110) comprising an electrode receiving surface portion (111) having substantially constant wetting tension throughout said electrode receiving surface portion, —providing a plurality of first electrodes (120) directly on said electrode receiving surface portion, —leaving intermediate portions (130) of said electrode receiving surface portion (111) free from said electrodes, —providing a layer of electrolyte (140) covering said plurality of first electrodes (120) and said intermediate portions (130), and—wherein wetting tension of the surfaces of the intermediate portions (130) is arranged to act more repelling on the electrolyte compared to the wetting tension of the surfaces of the plurality of first electrodes (120), whereby, the electrolyte is concentrated to the surfaces of the plurality of first electrodes (120), and the surfaces of the intermediate portions (130) are substantially free of electrolyte.
