| abstract |
The present comprises an electrode having thenconfiguration: first active material/current collectornscreen/second active material. When one of the activenmaterials is in a powder form, it is possible for thatnmaterial to move through openings in the currentncollector screen to "contaminate" the interface betweennthe other active material and the current collector. nThe present invention consists of having the othernelectrode active materials in a form incapable of movingnthrough the current collector to the other side thereof.nThen, the assembly is pressed from the direction of thenother electrode active material. This seals off thencurrent collector as the pressing force moves thencurrent collector against the powdered electrode activenmaterial. |
