Abstract
The invention relates to a lithium electric cell comprising, in a first embodiment, a lithium negative electrode and a positive electrode made in particular of copper sulphide, the electrolyte comprising a salt such as tetralkylammonium having predominantly anionic conductivity and, in a second embodiment, said cell comprises between the electrodes a separation membrane made of an anionic exchanger material such as quaternized polyvinylpyridine, the electrolyte of the cathode compartment being tetralkylammonium chloride, the electrolyte of the anode compartment being a salt such as lithium perchlorate having predominantly cationic conductivity. The invention is implemented in cells in thin layers.
