Abstract

An electrochemical modular accumulator of electric charge allows to optimize the shape of the accumulators and the position of their connectors so as to be able to implement clusters of batteries, by stacking them on each other, without the need to create an external self-supporting structure, and to reduce the overall dimensions without reducing the effectiveness, and comprises a casing made of polymeric material intended to contain an electrolyte liquid, inside thereof a sequence is contained wherein one or more anode electrodes, one or more separators and one or more cathode electrodes alternate. Said accumulator also comprises at least a pair of connectors crossing said sequence, wherein each connector crosses the anode at a connection hole, the separator and, without contact, a corresponding through-opening of the cathode and vice versa.
