Abstract
The invention relates to an electrochemical lithium accumulator comprising at least one first electrochemical cell and at least one electrochemical cell separated from each other by a current collector substrate, which substrate supports on a first face an electrode of said first electrochemical cell and on a second face opposite to said first face, an electrode of opposite sign of said second electrochemical cell, each cell comprising a positive electrode and a negative electrode separated by an electrolyte, characterized in that the positive electrode comprises a lithiated compound and the negative electrode comprises elemental sulfur.
