Ribbon shaped electrode e.g. anode, manufacturing method for rechargeable battery cell of e.g. lithium ion battery, involves applying dry electrically conductive powder on electrode mass, where powder is applied by roller system

摘要

The method involves applying dry electrically conductive powder on an electrode mass, where the dry electrically conductive powder is applied by a roller system on a coated plastic foil and subsequently on the electrode mass. The coated plastic foil is brought in direct contact with the supplied electrode mass in such a manner that an electrically conductive intermediate layer of the dry electrically conductive powder is applied on the electrode mass. An electrode mass-powder compound is applied on a collector foil and hot sealed in a laminating unit. Independent claims are also included for the following: (1) a device for manufacturing ribbon shaped electrodes for rechargeable battery cells (2) a ribbon shaped electrode for rechargeable battery cells.
