Abstract: A method for fabricating the electrochemical device includes provision of a first stack. This first stack successively includes: a first electrode, an electrically insulating liquid electrolyte in contact with the first electrode, a second electrode separated from the first electrode by the liquid electrolyte. The method includes an at least partial polymerisation step of the liquid electrolyte.

Abstract: The method for producing a stack of films provided with at least one 3D-structured pattern including providing a first mold having a textured front face including a first 3D pattern, depositing a first layer of the stack on the textured front face so as to cover the first 3D pattern by a continuous layer, the first layer having a first face in contact with the front face of the mold, removing the first mold so as to release the first face of the first layer having a second 3D pattern complementary to the first 3D pattern and depositing a second layer of the stack on the first face of the first layer so as to cover the second 3D pattern by a continuous layer.

Abstract: A cable-type battery comprising: at least a first strand of a first polarity type, at least a second strand of a second polarity type, the second polarity type being the opposite of the first polarity type, an electrolyte layer in which the first strand and the second strand are arranged, the electrolyte layer being ionically conducting and electrically insulating, the first strand being ionically connected to the second strand. The first strand is coated by a spacer layer, the spacer being electrically insulating, the spacer being configured to prevent any direct contact between the first strand and the second strand. The strength of the material forming the spacer is greater than the strength of the material forming the electrolyte layer.

Abstract: Method for an electrochemical device electrode enrichment, with ionic-species, including steps of: providing a substrate with at least one stack including: a first current-collector covering at least part of the substrate, first electrode covering at least part of the first current-collector, the first electrode being in electric contact with the first current-collector, protective layer totally covering the first electrode and at least part of the first current-collector, the protective layer being electrically insulating and ionically conducting; immersing in an electrolytic solution: the substrate provided with stack, counter-electrode made from conducting material, the electrolytic solution including at least one ionic-species salt and/or counter-electrode including ionic-species, applying electric voltage or current, with voltage or current generator, between first current-collector and counter-electrode making the ionic-species migrate to the first electrode and enrich the first electrode with ionic-spe
