Patent

CA 2631012

A method and a device for manufacturing a battery having a plurality of electrodes, wherein the method includes the step of forming non-formed active material on each electrode. The invention is distinguished in that the electrodes and thereby initially non-formed active material are held under a mechanical pressure during the formation step in order to limit the volume change of the active material during this step. The invention also concerns a battery.

La présente invention concerne un procédé et un dispositif destinés à fabriquer une batterie munie d~une pluralité d~électrodes, le procédé consistant à former un matériau actif brut sur chaque électrode. L~invention se caractérise en ce que les électrodes et donc le matériau actif à l~origine brut sont maintenus sous une pression mécanique lors de l~étape de formation afin de limiter la variation de volume dudit matériau pendant cette étape. L~invention concerne également une batterie.
