Abstract: The present invention relates to an electrochromic solution and a use thereof, wherein the said solution comprises: a solvent; a thickening polymer agent having a molecular weight of at least 50,000 g/mol, preferably 200,000 g/mol, more preferably of at least 250,000 g/mol; at least an additive having a molecular weight between 300 and 50,000 g/mol, preferably between 320 and 20,000 g/mol; a redox chemical mixture in solution in said solvent said mixture being constituted of at least one electrochromic reducing compound and at least one electrochromic oxidizing compound, and which colors in the presence of an applied voltage and which bleaches to a colorless condition in the absence of an applied voltage. The invention further relates to a device comprising said solution.
