BATTERY CELL ASSEMBLY FOR SECONDARY LITHIUM BATTERY WITH HEAT DISSIPATION FUNCTION Russian patent published in 2025 - IPC H01M10/52 H01M10/613 H01M10/647 H01M50/211 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to an element of an accumulator assembly of a secondary lithium accumulator with a heat dissipation function and can be used for heat removal in multi-element assemblies of lithium accumulator batteries. Secondary lithium battery cell is rectangular and is provided with an outer edge framing the side surfaces of the battery element and both terminal blocks, wherein the outer edge consists of double-sided external blocks that frame and close the terminal blocks on both ends of the battery element, and an external unit that frames and covers one of the side surfaces of the battery element. Assembly of the lithium battery is improved so that heat generated by the battery element can be quickly removed during charging and discharging, thereby reducing heat generated by the lithium secondary battery inside the battery module, which improves battery performance and its useful life. Besides, in the corner of the square part of the outer edge there is a hole, in which the fastening screw is installed to maintain the position of the outer edge when laying multiple elements of the accumulator one after another.

EFFECT: longer service life of the lithium battery due to fast heat dissipation during charging and discharging of the lithium battery is the technical result.
