Low-maintenance nickel-cadmium accumulator comprising a set of positive electrodes, a set of negative electrodes whose active mass is consolidated by a polymer and separators consisting of at least one matting made from a material chosen from a polyamide, polypropylene, polyethylene, singly or mixed, without an additional membrane, characterised in that the inter-electrode distance is between 0.2 mm and 0.5 mm, that the internal pressure is held between 0 and 0.7 bars, and that the said accumulator contains free electrolyte, so as to exhibit, within temperature limits of between -30 DEG C and +60 DEG C, when charged at constant voltage, a charge characteristic allowing the self-limiting of this charge. <IMAGE> |
