MULTILAYER BATTERY Russian patent published in 2014 - IPC H01M2/26 

FIELD: electricity.

SUBSTANCE: bipolar battery is designed by means of layering of multiple bipolar electrodes, each of which is formed by multi-layered current collector, layer of active material of the positive electrode located on one surface of the current collector, and layer of active material of the negative electrode located on other surface of the current collector, through the electrolyte layer. The lead (21a, 21b) for voltage determination is attached to a part of a peripheral edge of the current collector. By means of arrangement of the lead (21b) for determination of voltage of adjacent current collector on the opposite side from the second direct line (Da2), which passes through centrodes (O) of the current collector and appears to be orthogonal to the first direct line (Da1), which connects the lead (21a) for voltage determination with the centroid (O) of the current collector, the charge state inside the identical battery accumulator unit (15) becomes uniform.

EFFECT: charge equalising in each battery accumulator unit.
