Abstract: The application discloses a method of liquid cold welding (LCW) including: (a) engaging two or more porous conductive substrate layers between perforated non-conductive frames so that the substrate layers contact one another; (b) immersing the substrate layers in an electrolyte solution; and (c) applying electric current and/or voltage and/or electric power to the electrolyte solution. Apparatus suitable for performance of some embodiments of the method are also disclosed.

Abstract: The present invention provides a foil with fine and uniform functional porosity that can be produced cheaply in roll-to-roll configuration, whereas the porosity stems from corrugation and/or perforation and of the foil. The presently disclosed augmented metallic foils are useful in many application, including, but not limited for use as current collectors in lithium-ion barratries.

Abstract: The present invention provides electrodes comprising a current collector in the form of an augmented metallic foil having a fine and uniform corrugation that augments the functional porosity of the foil. The presently disclosed electrodes having augmented metallic foil, exhibiting high functional porosity, as current collectors are useful in many application, including, but not limited to lithium-ion barratries and electric devices using the same for energy.

Abstract: A system for loading and clamping one or more plates onto the cylindrical surface of a rotatable drum, such as used in a platesetter for printing, and for unloading the plates from the drum. The system is characterized by clamps that are movable over the surface, preferably along circumferential tracks, enabling the attachment of multiple plates, end-to-end and/or side-by-side, each plate having any of a wide range of sizes. The clamps are preferably of the dynamic type, whereby the clamping force increases with rotational speed. Also disclosed is a method for mounting and unmounting plates, using the movable clamps, such that allows flexible and convenient arrangement of loading- and unloading stations.
