Abstract: A three-dimensional (“3D”) printing system for printing on a substrate, the printing system including a powder distribution device dispensing powder on the substrate and including a blade-shaped end, the blade-shaped end disposed at a height above the substrate; a powder uniformization device located at a distance from the powder distribution device along a direction substantially parallel to a longitudinal axis of the substrate; one or more sensors disposed upstream from the powder uniformization device and configured to determine one or more parameters of a thickness of the dispensed powder at one or more locations; and a control apparatus configured to determine whether the one or more parameters of the thickness is above a predetermined threshold value, and if the one or more parameters is determined to be above the predetermined threshold value, to adjust the powder distribution device.

Abstract: An electrochemical cell is provided, which includes a cathode comprising a three dimensional (3D) porous cathode structure, an anode, an electrolyte separator, comprised of a ceramic material, located between the cathode and the anode, and a cathode current collector, wherein the cathode is located between the cathode current collector and the electrolyte separator. The 3D porous cathode structure includes ionically conducting electrolyte strands extending through the cathode from the cathode current collector to the electrolyte separator, pores extending through the cathode from the cathode current collector to the electrolyte separator, and an electronically conducting network extending on sidewall surfaces of the pores from the cathode current collector to the electrolyte separator.

Abstract: An electrochemical cell is provided which includes a cathode, an anode, an electrolyte separator, and an anode current collector located on the anode. The anode is a three-dimensional (3D) porous anode including ionically conducting electrolyte strands and pores which extend through the anode from the anode current collector to the electrolyte separator. The anode also includes electronically conducting networks extending on sidewall surfaces of the pores from the anode current collector to the electrolyte separator.

Abstract: A three-dimensional (3D) printer and method are provided, including a substrate, a liquid deposition device configured to deposit a liquid dispersion including a suspension of a particulate material in a liquid vehicle, the liquid vehicle including a solvent but devoid of a binder material, onto the substrate to form a non-patterned layer on the substrate, a solvent removal device configured to remove at least a portion of the solvent from the liquid vehicle from the non-patterned layer to form a dried non-patterned layer, and a liquid binder print head configured to deposit a liquid binder onto the dried non-patterned layer to form a printed pattern on the dried non-patterned layer.
