ELECTRODE FOR PROTECTION AGAINST BATTERY DAMAGE IN CASE OF SHORT CIRCUIT Russian patent published in 2022 - IPC H01M10/525 H01M4/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in the manufacture of lithium-ion batteries to protect them from damage as a result of a short circuit. The expected result is achieved by using a sublayer material with a positive thermoresistive effect and a positive potentioresistive effect in the region of low potentials from 2 to 5 V. The electrode for protection against battery damage in case of a short circuit contains an electrically conductive current supply with a protective layer, an electroactive mass, while the protective layer is made with a thickness of 25 nm - 10 microns from a conductive polymer with transition metal complexes, including nickel, which is formed when the working electrode is immersed in a cell with 0.01 Μ monomer solution [NiCH₃OSalEn].

EFFECT: increased reliability of the protection against short-circuit currents at the stage of thermal acceleration, as well as increased magnitude of the change in the intrinsic resistance of the electrode.
