BATTERY CELL Russian patent published in 2022 - IPC H01M10/525 H01M10/563 H01M10/568 H01M4/505 

FIELD: power sources.

SUBSTANCE: invention relates to the field of electrical engineering, namely to a battery cell with an electrolyte based on SO₂. The result is achieved due to the fact that the battery cell (2, 20, 40) contains an active metal, at least one positive electrode (4, 23, 44), at least one negative electrode (5, 22, 45), the housing (1, 28) and the electrolyte, while the positive electrode (4, 23, 44) is made in the form of a high-voltage electrode, the electrolyte is based on SO₂ and contains at least one first conductive salt of formula (1)

where: M is a metal selected from a group consisting of alkali metals, alkaline earth metals, metals from group 12 of the Periodic Table of Elements and aluminum; x is an integer from 1 to 3; substituents R¹, R², R³ and R⁴ are selected independently from each other from a group consisting of C₁-C₁₀ alkyl, C₂-C₁₀ alkenyl, C₂-C₁₀ alkynyl, C₃-C₁₀ cycloalkyl, C₆-C₁₄ aryl and C₅-C₁₄ heteroaryl; Z stands for aluminum or boron.

EFFECT: increasing the reliability and service life of the battery with a high discharge capacity and cycling.
