    Abstract: A system for forming a micro-truss structure including a reservoir having walls and a flat bottom configured to hold a volume of a liquid photomonomer configured to form a photopolymer when exposed to light, a partially transparent mask secured to, or being, the bottom of the reservoir, a release layer on the mask configured to resist adhesion by the photopolymer, and a blocker positioned a first distance below the mask. The system also includes a light source positioned below the blocker configured to produce collimated light suitable for causing conversion of the photomonomer into the photopolymer, and to which the blocker is opaque, and a first mirror, oblique to the blocker, configured to reflect the light from the light source around the blocker and through the mask and into the reservoir. The blocker is positioned to block a straight path of light from the light source to the mask.

    Abstract: An ordered open-cellular carbon microstructure and a methods for forming the ordered open-cellular carbon microstructure capable of greatly improving the carbon yield (remaining mass % after carbonization) of an open-cellular polymer material. In one embodiment, the method starts with providing an ordered open-cellular polymer template material. The polymer template material is immersed in a reservoir containing a liquid monomer solution, wherein the liquid monomer solution swells the polymer material. Then the polymer template material is removed from the reservoir containing liquid monomer solution. Excess liquid monomer solution is removed from the polymer template material. The liquid monomer solution absorbed into the polymer template material is polymerized forming a copolymer material by irradiating the template material with ultraviolet (UV) light in a nitrogen environment. The copolymer material is heated in an inert atmosphere, wherein the copolymer material is carbonized resulting in the ordered open-cellular carbon microstructure.

    Abstract: A method for creating a sandwich panel heat pipe is disclosed. A three-dimensional ordered micro-truss core comprising a plurality of periodically disposed unit cells comprising an open-cellular microstructure and a free space defined by the open-cellular microstructure wherein the core comprises a vapor region and a liquid region separated by a mesh structure. A first face sheet and a second face sheet are stacked with the three-dimensional ordered micro-truss core to form a heat pipe assembly with the mesh structure in the three-dimensional ordered micro-truss core being planar and substantially parallel to the first face sheet and the second face sheet. The first and second face sheets are bonded to enclose the three-dimensional ordered micro-truss core wherein the free space of the three-dimensional ordered micro-truss core between the first and second face sheets is filled with a working fluid through an inlet and the inlet is sealed.

    Abstract: A new battery structure as disclosed allows convective flow of electrolyte through three-dimensional structured electrodes. Hierarchical battery structure design enables three-dimensional metal structures with fluid transport capabilities. Some variations provide a lithium-ion battery system with convective electrolyte flow, comprising: a positive electrode comprising a lithium-containing electrode material and a conductive network with hollow liquid-transport conduits; a negative electrode comprising a lithium-containing electrode material in the conductive network; a separator that electronically isolates the positive and negative electrodes; and a liquid electrolyte contained within the hollow liquid-transport conduits of the conductive network. The hollow liquid-transport conduits serve as structural members, and the walls of these conduits serve as current collectors. The conductive networks may include a micro-lattice structure with a cellular material formed of hollow tubes. Performance and thermal management of lithium-ion batteries (and other types of batteries) can be improved.
