LITHIUM SECONDARY ACCUMULATOR CELL UNIT Russian patent published in 2025 - IPC H01M50/202 H01M10/52 

FIELD: electric elements.

SUBSTANCE: invention relates to a unit of accumulator cells of a lithium secondary accumulator. Accumulator cell unit consists of a battery cell of rectangular shape, an outer edge framing the side surfaces of the accumulator cell and both terminal blocks of the accumulator cell, and holes for installation of screws provided in square corner blocks of outer edge, in which fastening screws are installed, and the length in the longitudinal direction of the accumulator cell assembly decreases as a groove is formed in the square corner unit of the accumulator cell, and part of the screw fastening hole provided in the square corner unit of the outer edge is located inside the groove.

EFFECT: improved operational characteristics and prolonged service life of the secondary accumulator due to minimization of heat generated by the lithium secondary accumulator inside the battery module.
