PACKAGED BATTERY Russian patent published in 2019 - IPC H01M10/585 H01M2/20 H01M2/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to a packaged battery, which includes at least one part of the shunting of short-circuit current and electrical elements, while the part of the shunting includes the first and second layers of the current lead and an insulating layer provided between the first and second layers of the current lead, all these layers are stacked on top of each other; each power generation element includes a cathode current lead layer, a cathode material layer, an electrolyte layer, an anode material layer, and an anode current lead layer, all these layers are stacked on top of each other; the first current collector layer is electrically connected to the cathode current lead layer, and the second current collector layer is connected to the anode current lead layer; electric elements are electrically connected in parallel; and the shunting part adjacent to the electrical elements includes a PPTC layer between the first current collector layer and the insulating layer and/or between the second current collector layer and the insulating layer.

EFFECT: suppressing the increase in temperature in the battery's electrical components when a short circuit occurs is a technical result of the invention.
