Abstract
The invention relates to a novel lithium-sulphur type electrochemical battery A. According to the invention, the positive electrode (1) is made solely from a porous electronic conductor substrate forming a current collector and the electrolyte contains lithium polysulphides (LiSn) as sources of lithium and sulphur ions, said lithium polysulphides being formed ex-situ and not in the battery. The invention also relates to a method for the production of said device.
