ABSTRACT:
A monobloc battery including a plurality of interconnected electrochemical cells formed from electrodes and electrolyte and having end poles, wherein distances between selected cells and the end poles and, optionally, distances between the selected cells, are set such that no voltages of more than about 30V occur between the distances under normal operating conditions of the monobloc battery, and at least one gas collecting line connected to selected cells and located to collect explosive gas mixtures, if any, generated by the cells, the gas collecting line being substantially electrically insulating and, in at least one area, having a lining composed of an electron-conductive material electrically conductively contacting the electrodes or the electrolyte in an individual cell.
