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.
