Electrochemical generator with lithium anode and liquid cathode

Electrochemical generator with a lithium anode and a liquid cathode consisting of a stack of flat elements enclosed in a case, each element comprising separators and electrodes fitted with a metal collector plate, each electrode presenting at least two openings whereby it is threaded to respectively at least two parallel metal rods with metal spacers to maintain the desired interval between the plates and to ensure electrical connection between the corresponding electrodes, wherein a first of the said metal rods connected to electrodes of a first polarity totally traverses the said stack, at least one electrolyte reserve compartment being disposed as a function of height of the stack between the latter and the said case, current collector lugs emerging in this compartment, said current collector lugs comprising a neck that constitutes a fuse, the said current collector lugs being threaded onto the second of the said metal rods and belonging to collector plates of electrodes of a second polarity, and one end of each of the said rods being rigidly attached to an end wall of the said case, the other end of each of said rods being allowed free motion within the said case.
