A supercapacitor cell is provided having unit cells arranged in series and encapsulated in a flexible and leak-tight packaging, and a supercapacitor module having at least one stack of several of these cells. The cell includes n unit cells (n&#x2267;2) arranged side by side in series and encapsulated in the packaging, each unit cell having two upper and lower electrodes, a membrane separating them and an ionic electrolyte, the cell having inside of the packaging a plurality of current collectors, two upper and lower collector parts of which respectively cover the upper and lower electrodes. A pair of adjacent unit cells is covered with an upper or lower collector common to this pair, two truncated upper and/or lower collectors formed at two ends of the cell, two adjacent collectors respectively terminated by facing edge sections electrically insulated from one another by an insulating adhesive material covering them.

Novel articles, in particular films, made from polymers, which are elastic, impermeable to water and permeable to water vapor. Said articles are made from a composition comprising a dispersion of an elastomer in an aqueous solvent, a hydrophilic compound and a cross-linking agent.

A subject-matter of the invention is a novel process for the preparation of sulphur-modified monolithic porous carbon-based materials by impregnation with a strong sulphur-based acid, the materials capable of being obtained according to this process and the use of these materials with improved supercapacitance properties to produce electrodes intended for energy storage systems. Electrodes composed of sulphur-modified monolithic porous carbon-based materials according to the invention and lithium batteries and supercapacitors having such electrodes also form part of the invention.
