Zusammenfassung:	An electrochemical cell sub-assembly and a method for manufacturing same. The electrochemical cell sub-assembly includes a current collector sheet having a pair of opposite surfaces and a pair of opposite edges, each surface being coated with a respective layer of electrode material. A layer of polymer electrolyte envelopes both layers of electrode material and one of the pair of edges of the current collector sheet, thereby encapsulating the one edge of the current collector sheet while leaving exposed the other edge of the current collector sheet. Un sous-ensemble de cellule électrochimique et un procédé pour le fabriquer. Ce sous-ensemble de cellule électrochimique comprend une feuille collectrice de courant pourvue dune paire de surfaces opposées et dune paire de bords opposés, chaque surface étant revêtue respectivement dune couche de matériau délectrode. Une couche délectrolyte polymère enveloppe les deux couches de matériau délectrode et un bord de la paire de bords de la feuille collectrice de courant, ce qui permet dencapsuler ce bord de la feuille, tout en laissant exposé lautre bord cette dernière.
