ACCUMULATOR BATTERY Russian patent published in 2015 - IPC H01M2/10 H01M10/02 

FIELD: electricity.

SUBSTANCE: present invention relates to the battery, in which the package electrode assembly (20) with the cathode, anode and separator (22) in located with the electrolyte solution between the external elements (30). Technology of connection of the external periphery area of the separator together with the tight areas of the external elements in the battery is known to prevent displacement of the package electrode assembly. But the problem during this technology use is that there are now measures to replenish the package electrode assembly with the electrolyte solution, and to prevent break in connection at the periphery area of the separator to keep the operating characteristics of the battery.

EFFECT: present invention solves such problems by the battery provision with many connection places, where the external periphery section of the separator is connected with the external elements and holding part, made at least between the connecting places to hold the electrolyte solution, at that sum of the perimeters of the connecting places exceeds the perimeter of rectangular with minimum area including all connecting places.
