Patent

CA 2243645

A method of fabricating electrochemical cells and batteries wherein the successive anode and cathode layers are separated by a polymeric electrolyte layer having a protruding polymer edge around its perimeter which reduces the likelihood of inadvertent contact between the anode and cathode current collectors is provided. The polymer edge functions as a non-conducting physical barrier positioned between adjacent current collectors. An apparatus for preparing electrochemical cells is also disclosed.

La présente invention concerne un procédé de fabrication de cellules et de piles électrochimiques dans lesquelles les couches successives d'anode et de cathode sont séparées par une couche d'électrolyte polymère présentant sur son pourtour un rebord polymère protubérant qui réduit la probabilité de contact accidentel entre les collecteurs de courant de l'anode et de la cathode. Le rebord polymère fonctionne comme une barrière physique non conductrice disposée entre des collecteurs de courant adjacents. L'invention concerne également un dispositif de réalisation de cellules électrochimiques.
