BATTERY BASED ON ORGANOSULFUR COMPOUND Russian patent published in 2021 - IPC H01M10/567 H01M10/568 H01M6/16 

FIELD: batteries.

SUBSTANCE: invention relates to an anode comprising active anode material containing sodium, lithium, potassium or magnesium, or an alloy or composite of at least one of metals of sodium, lithium, potassium or magnesium with at least one other metal to provide ions, where the anode additionally includes at least one organosulfur compound, or the anode has been pretreated with at least one organosulfur compound, while the specified organosulfur compound is selected from a group consisting of organic polysulfide of the formula R¹-S-S_n-R², where R¹ and R² are independently a C₁-C₂₀ organic fragment, which can be linear, branched or cyclic aliphatic or aromatic, and n is an integer equal to or greater than 1, organic thiolate of the formula R¹-S-M and organic polythiolate of the formula R¹-S-S_n-M, where R1 is a C₁-C₂₀ organic fragment, which can be linear, branched or cyclic aliphatic or aromatic, M is lithium, sodium, quaternary ammonium, or quaternary phosphonium, and n is an integer equal to or greater than 1.

EFFECT: use of the proposed anode makes it possible to improve operational characteristics of electrochemical elements during repeated discharge and charging cycles.
