Abstract
The invention concerns a process for manufacturing a double-layer electrolyte/electrode electrochemical sub-assembly comprising a positive composite electrode layer and a superimposed electrolyte layer, said layers each containing an ionically-conducting macromolecular material and having at their interface a physical and chemical continuum between the macromolecular material of the electrolyte and that of the electrode, and the sub-assembly so obtained. The process consists in depositing one of the layers on a support from a fluid phase containing the constituents of this layer, partially cross-linking the layer, and then spreading the other layer on this partially cross-linked layer from a fluid phase containing the constituents of the other layer and capable of dissolving the macromolecular material of the first layer deposited on the support. Application of the double-layer sub-assembly to the fabrication of electrochemical cells in the form of thin layers.
