SPRAY PRINTING OR SPRAY DEPOSITION METHOD FOR THE PRODUCTION OF A SUPPORTED FLEXIBLE ELECTRODE AND MANUFACTURE OF A LITHIUM-ION BATTERY Russian patent published in 2018 - IPC H01M4/04 H01M10/525 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to a spray printing or spray deposition method for producing a supported flexible electrode. Method for producing a supported flexible electrode includes the following steps: i) preparing an electrode dye by dispersing a mixture of solids in an aqueous phase, the mixture of solids comprising: one active electrode substance in an amount of 70 to 99.5 % by weight of the total mass of the solid particle mixture, one binder containing the lignocellulosic material in an amount of 0.5 to 30 % by weight of the total weight of the mixture of solid particles, mixture of solid particles is at least 25 % by weight of the total weight of the electrode ink; ii) step of transferring the electrode ink to at least a portion of one side of the flexible substrate by a printing or sputtering method, the flexible substrate being selected from a cellulosic substrate, polymer film and a polymer membrane, optionally reinforced cellulose; and iii) drying step for obtaining a flexible electrode on the substrate.

EFFECT: invention makes it possible to obtain soft lithium batteries having good electrochemical characteristics and easy to assemble.
