ACCUMULATOR BATTERY Russian patent published in 2014 - IPC H01M10/04 H01M2/02 H01M2/18 H01M2/36 H01M10/585 

FIELD: electricity.

SUBSTANCE: invention relates to the accumulator battery, in which the packaged electrode assembly (20) with the cathode, anode and separator (22) are enclosed together with the electrolyte solution between external elements (30). The technology of connection of an external peripheral section of the separator together with encapsulated sections of external elements in the accumulator battery, preventing a displacement of the packaged electrode assembly is known. However, the problem of this technology is in that no measures are provisioned to refill the packaged electrode assembly with an electrolyte solution and to prevent disrupture in the place of connection at the external peripheral section of the separator with the purpose of maintaining of working characteristics of the battery. The present invention solves such problems by means of provisioning in the accumulator battery of multiple places of connection, where the external peripheral section of the separator is connected with external devices, and with retaining part formed, at least, between the connection places to retain inside the electrolyte solution. While the sum of perimeters of connection places of is greater, than the perimeter of rectangle of the minimum area enclosing all connection places.

EFFECT: improved characteristics.
