METHOD OF MAKING ELECTRODES OF A CHEMICAL CURRENT SOURCE Russian patent published in 2019 - IPC H01M6/14 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to design of a chemical current source (CCS) with a cathode made using thin-film technology. According to the invention, in the method of manufacturing a chemical current source with a thin-film electrode cathode, in which the positive and negative electrodes are made in the form of a carbon matrix of a roll material having high porosity, porous matrices of positive and negative electrodes are filled with chemically active material with layer thickness of 20 nm to 2 mcm, which is uniformly distributed on surface of carbon matrix, current collector of positive and negative electrodes is made in the form of metal layer with thickness of 2 to 10 mcm, which is applied on vacuum thin-film technology on porous carbon matrix, wherein planar electrode with annular spraying zone is used, at sputtering magnetron source is used, which is current-conducting plate from any conducting material, which is target cathode, anode is made in the form of hollow metal tube with water cooling, cathode and anode are connected to high-voltage direct current source, as working material for primary metallization titanium (Ti) is used, titanium nitride (Ti) is used for finish metallization, active material layer is applied by means of a liquid paste application onto metallized electrode material, by vacuum impregnation or by means of a vacuum printer, current collector of positive and negative electrodes is made in the form of tape titanium foil, which is coated with titanium nitride, part of which is used for tight outward output of CCS housing, and most part is fixed to current collector using ultrasonic or spot welding.

EFFECT: increased power and fire-explosion safety, reduced heat dissipation in CCS due to reduced electric resistance of electrode materials.
