Multicavity electric power accumulator

A high capacity and resistance electric power accumulator comprising:

• an outer insulating case configured for containing an electrolyte,
• a block accommodated inside said insulating case, said block comprising a plurality of conductive material regions, said plurality of conductive material regions forming positive electrodes and negative electrodes, alternating with a plurality of insulating material regions, and forming separators, and
• a plurality of adjacent cavities, said plurality of adjacent cavities forming a structure of said conductive material regions and spaces between said conductive material regions, each provided with a plurality of holes on wall thereof so that, whenever the block is dipped into the electrolyte, the electrolyte can flow and also enter the inside of the cavity,
• wherein said cavities are aligned and superimposed to each other in such a way as to form an alveolar structure suitable for accommodating ducts passing through a portion of the block and configured in such a way as to make the electrolyte flow internally to the accumulator and to extract it therefrom.
