Abstract:
1. An electrochemical device, comprising: a flexible substrate; a first and a second layer of electrically conductive and electrochemically active material, which are spatially separated from each other and carried by said flexible substrate; an electrolyte composition, which ionically connects said first and said second layer, wherein the redox state of said first layer is controllable by means of a voltage applied across said electrolyte composition, and wherein said first layer is arranged such that a change in the redox state alters the electrical conductivity of said first layer, and the electrolyte composition includes, before drying and curing, (i) 20-50% by weight, based on the total amount of the electrolyte composition, of a radiation-curable base which comprises (ii) 20-50% by weight, based on the total amount of the electrolyte composition, of water, and (iii) 10-50% by weight, based on the total amount of the electrolyte composition, of an electrolyte, wherein the electrolyte composition has a viscosity of 0.3 Pas or higher.
