METHOD OF PRODUCING TiS BASED ELECTRODES FOR ELECTROCHEMICAL ENERGY STORAGES WITH INORGANIC AQUEOUS Mg-ION ELECTROLYTE Russian patent published in 2020 - IPC H01M4/13 H01M4/136 H01M10/54 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and specifically to a method of producing electrode material for use in Mg-ion batteries meeting environmental requirements, which is an urgent problem of power engineering. To obtain an electrode, initial elementary sulfur, titanium powder (150–300 mcm, 80 mesh) or ground titanium sheet pieces are used as initial reagents, which are fired in a sealed pyrex ampoule for 12 hours at 400 °C with isothermal holding, after which, based on the obtained powdered product, a paste is prepared, which contains 75 % of the obtained powdered product, 5 % fluoroplastic and 20 % of soot, which are mixed and grinded in mortar for 15–20 minutes, then poured into an Eppendorf tube and a solvent is added, the amount of which is selected depending on the weight of the dry substance and the desired consistency of the solution, then the solution is mixed and deposited on the steel mesh, which is dried in vacuum furnace for 2 hours at 60 °C. Electrode material obtained during solid-phase synthesis has high Mg²⁺-ionic and electronic electrical conductivity at room temperature, and also has high specific capacitance (709.3 F/g), charge/discharge rate and stability.

EFFECT: technical result of invention is increase of homogeneity of composite electrode material, having low resistance.
