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.
Composition permitting an application of a coating on a support at low temperature from a dispersion in said composition, of at least one component to be deposited on said support, said composition comprising at least one strong and heavy solvent in which the boiling temperature is higher than about 150° C. and a weak solvent in which the boiling temperature is lower than about 100° C., the strong and heavy solvent and the weak solvent, constituting a mixture which evaporates at a temperature lower that about 100° C.
Composition according to claim 1 or 5, characterized in that the weak solvent is selected from acetone or ethyl acetate.
Process of applying a coating on a support characterized by the following steps:
