Abstract: A method of manufacturing an electrochemical system comprising an electrode is described herein, comprising dispensing, in a configured pattern corresponding to the shape of the electrode, a model composition which comprises a substance capable of reversibly releasing an electrochemically-active agent (such as lithium) or depleted form of same, wherein dispensing comprises heating a filament comprising the model composition and dispensing a heated composition. Further described is an electrochemical system comprising an electrode which comprises a composite material, as well as batteries and supercapacitors comprising such a system. The composite material comprises a thermoplastic polymer and substance capable of reversibly releasing an electrochemically-active agent (such as lithium) or depleted form of same, wherein at least 20 weight percents of the composite material is thermoplastic polymer.

Abstract: An electrical energy storage device (20) includes a substrate (22), an anode layer (30), a cathode layer (26), and a separator layer (28) between the anode layer and the cathode layer. The substrate has multiple sets of intersecting cavities (21) passing through the substrate in different directions. The anode layer, cathode layer, and separator layer are formed over a surface of the substrate within the cavities.

Abstract: A public presentation system is presented comprising a display system that can be remotely changed, so that multiple different images are successively displayed with minimal interruption. The system utilizes ionography techniques for non-contact printing and imaging for display. Thus by exploiting electrostatic imaging techniques, an advertisement can be displayed promptly by transferring a toner image onto an imaging belt.

Abstract: A wide format printing system, apparatus and method are provided to enable standard printing units to print images in a selected wide format. In some embodiments the printing system includes a printing controller, image recognition unit, and a wide format printing apparatus including a plurality of printing sub-units being positioned to precisely cover the width of a substrate of selected size.

Abstract: An electrophotographic printing apparatus and method are provided to separate particles of at least one toner color from a mixture of colored toner particles. The toner separating apparatus may include a charging source, developer unit, and illumination unit that may illuminate a drum surface using one of more light wavelengths, after the developer has covered the drum surface with multi-color toner mixture. The printing apparatus may enable separation of a mixture of colored toner particles into the component colors, thereby enabling re-using of erased toner particles collected from previously erased colored images.

Abstract: A printing apparatus and display system including a detachable printing apparatus that enables printing and/or erasing of display information directly to and/or from display systems. The printing apparatus may print and delete color images to/from a substrate using a printing mechanism and a plurality of color toners, using a detachable mobile printing apparatus. The printing apparatus may enable recycling of erased toner from previously erased images.

Abstract: A system, apparatus, and method for toner recycling in a printed image display system. The display system, in conjunction with the printing apparatus, according to some embodiments of the present invention, may enable printing a color image using a plurality of toner colors, erasing the image from the substrate, collecting the erased mixture of toner colors, separating the toner colors, and recycling the toner colors for use in further printing.
