Abstract: An electrochemical storage device comprises a plurality of layer electrodes each including a first charged sector and a second charged sector. The plurality of layer electrodes are assembled with respect to each other such that the first charged sector of a first plate of the plurality of layer electrodes is laid below the second charged sector of a second plate of the plurality of layer electrodes located immediately above the first plate. The charges of the first charged sectors of the first and second plates have a first sign and the charges of the second charged sectors of the first and second plates have a second sign that is opposite the first sign. The device also comprises a separator sector located, and enabling ionic charge exchange, between the first charged sector of the first plate and the second charged sector of the second plate.
