MULTILAYER STORAGE BATTERY Russian patent published in 2019 - IPC H01M10/585 H01M10/42 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment, in particular to the multilayer storage battery, in which the short-circuit resistance non-uniformity among plurality of battery cells is suppressed. This problem is solved by the multi-layer storage battery execution, containing: plurality of battery cells, stacked, at that, the battery cells plurality is electrically connected in parallel, and each of plurality of the battery cells includes a cathode current lead, cathode active material layer, a solid electrolyte layer, an anode active material layer and the anode current lead. Multilayer storage battery includes a battery cell located on top of the multilayer storage battery stack, and located in the stack center the battery cell, at that, the contact resistance between the cathode current lead and the anode current lead in the battery cell on the surface side is larger, than the contact resistance between the cathode current lead and the anode current lead in the battery cell from the center side.

EFFECT: technical result of the invention is the short circuit resistance alignment among plurality of battery cells and increase in battery life.
