Abstract
A composition for applying a coating on a support at low temperature from a dispersion of at least a component of the coating to be deposited in the composition. The composition includes at least a strong and heavy solvent with a boiling point higher than 150° C. approximately, and a weak solvent with a boiling point less than 100° C. approximately. The solvents forming the composition must constitute a mixture that evaporates at a temperature less than 100° C. The composition is particularly useful for forming electrodes or electrolyte in lithium-ion batteries. The method and the device used for forming the coating use a dispersion spreader and an infrared lamp.
