ANODE OF LITHIUM-ION BATTERY FOR OPERATION AT LOWER TEMPERATURES AND METHOD FOR PRODUCING IT Russian patent published in 2021 - IPC H01M4/36 H01M4/139 H01M10/525 

FIELD: electrical industry.

SUBSTANCE: invention relates to electrical manufacturing industry, namely to devices for the direct conversion of chemical energy into electrical energy, and specifically to a lithium-ion battery. Method of manufacturing an anode lithium-ion battery includes deposition of arrays of indium nanoparticles on a substrate using vacuum-thermal evaporation from a molybdenum evaporator at a residual pressure of 1×10^–5 torr and a distance from the evaporator to the substrate of 20 cm; annealing the substrate in vacuum at a temperature of 150°C for 10 min; cathodic deposition on the substrate from a solution containing 0,05 М GeO₂, 0,5 М K₂SO₄ and 0,5 М amber acid; bringing the pH of the solution to 6.5 by adding NH₄OH; maintaining the solution temperature at 90°C; deposition in galvanostatic mode at the current density of 2 мА/cm². The anode of a lithium-ion battery is manufactured of nanofibrous germanium, grown directly on a conductor substrate, without the use of binders and electrically conductive additives.

EFFECT: increased specific energy of the lithium-ion battery, as well as achieved possibility of its operation at low temperatures.
