Abstract
The invention relates to an electrochemical lithium accumulator comprising a stack of at least two electrochemical cells, each cell being separated from its adjacent cell by a current-collecting substrate, a first face of this substrate being occupied by an electrode of a cell while a second substrate face opposite to the first is occupied by an electrode of its adjacent cell, each cell comprising a positive electrode and a negative electrode separated by an electrolyte, characterized in that the electrolyte comprises a lithium polysulfide additive.
