Abstract:
The invention relates to a positive electrode for a lithium-sulfur electrochemical accumulator comprising an electrically conductive substrate selectively coated, over at least one of its faces, with carbon nanotubes so as to create a zone coated with carbon nanotubes within which a plurality of separate zones without carbon nanotubes are arranged, these separate zones being qualified as empty.
