METHOD OF MAKING LITHIUM-ION CURRENT SOURCE WITH ANODE BASED ON SILICON Russian patent published in 2024 - IPC H01M4/13 

FIELD: distributed power engineering.

SUBSTANCE: invention relates to portable electric energy storage devices with improved energy characteristics. Method of making a lithium-ion current source with an anode based on silicon involves electrodeposition of a solid film of silicon from a molten electrolyte on a graphite current lead and use of obtained composition as anode with current lead in unit cell of lithium-ion current source, note here that electrodeposition of 1–8 mcm thick silicon film on graphite current lead is performed from molten chloride-fluoride electrolyte LiCl-KCl-CsCl-K₂SiF₆ at temperature not higher than 650 °C.

EFFECT: reduction of costs for production of anode material of lithium-ion current source, expansion of range of permissible materials of current lead to anode, reduction of oxygen in composition of anode of lithium-ion current source and increase of its specific capacity.
