Abstract
The invention relates to an electrochemical sub-assembly comprising a positive electrode and a solid polymer electrolyte. The solid polymer electrolyte is composed of a salt in solution in a macromolecular material. The electrode is composed of the product of agglomeration in a composite mass of a material with ion conduction, composed of a salt in solution in a macromolecular compound of an electrochemically active material and an electron condutor material. The electrode and the electrolyte layers possess good adhesion to one another and do not possess any preferential orientation of the chains of the macromolecular material at the electrolyte/electrode interface.
