COUNTER ELECTRODE FOR ELECTROCHROMIC DEVICE AND ITS MANUFACTURING METHOD Russian patent published in 2017 - IPC G02F1/15 H01M10/525 

FIELD: chemistry.

SUBSTANCE: invention relates to a counter electrode and an electrochromic device and its manufacturing method and can be used in the manufacture of smart glass or translucent structures with electrically controlled light transmission variable. A process for preparing a counterelectrode comprises obtaining the active layer having a high capacity for intercalation of lithium ions of the composition containing in % by weight in terms of dry substance: material with a high intercalation capacity - from 70.0 to 99.8;. electroconductive additive - 0.1 to 10.0; binder - 0.1 to 10.0; stabilizer - from 0.0 to 10.0, and the solvent - the rest. The ingredients of the composition are mixed and then applied by available printing methods on the substrate surface with a transparent electrically conductive material so that the surface area ratio, is free from the opaque material, is 92÷97%. Lithium cobaltate LiCoO₂ and/or lithium ferrophosphate LiFePO₄ and/or lithium manganate LiMn₂O₄ are used as materials with high lithium intercalation capacity.

EFFECT: invention provides improvement of electrochemical stability of the counter electrode, as well as increase in the number of working dye-bleaching cycles in the electrochromic device, that is the technical result of the invention.
