A battery module including at least one cell, at least one sensor, an interrupter device such as a fuse connected in series with the cells and an electronic switch. The electronic switch includes power transistors for short circuiting the series-connected components and the fuse if the sensor senses a malfunction and a diode for assuring that the power transistors maintain the series-connected circuit short circuited regardless of the subsequent status of the sensor. The diode memorizes the malfunction so that the module continues to conduct after the fuse blows, even if the sensors no longer detect any malfunction.

Protection for battery module with diode memory

An activatable electrochemical battery implementing lithium/oxyhalide couples. The present invention relates to an activatable lithium/SOCl.sub.2 or lithium/SO.sub.2 Cl.sub.2 primary battery in which means are provided for eliminating leakage currents and means are provided for controlling the temperature rise during discharge. Thus, each electrochemical element is enclosed, in a sealed insulating housing constituted by a bottom, a cover, and a spacer constituting its side wall. The terminals of the elements are plates of nickel enabling heat to be dissipated into a heat-conducting resin.

Activatable electrochemical battery implementing lithium/oxyhalide

The electrode structure includes electrolyte injection and collector channels, and, on pairs of opposite sides of each battery cell (1), plates (2) for distributing electrolyte through said cells, said plates being disposed to ensure that the flow of electrolyte through each cell is substantially constant over any point of the area of said cell.

Electrode stacking structure in an activatable battery

The present invention concerns an electrochemical generator with a lithium anode and liquid cathode and, notably, generators using the Li/SO.sub.2, Li/SOCl.sub.2 and Li/SO.sub.2 Cl.sub.2 couples. This generator comprises of stack of flat elements threaded onto rods, one end of each rod being attached to the cover of a case. The anodes are threaded by flexible lugs which act as current collectors and fuses.
