A device and method of making and using the same. The device includes first and second substrates that are spaced to define a fluid space. Polar and non-polar fluids occupy the fluid space. A first electrode, with a dielectric layer, is positioned on the first substrate and electrically coupled to at least one voltage source, which is configured to supply an electrical bias to the first electrode. The fluid space includes at least one fluid splitting structure that is configured to facilitate the movement of the non-polar fluid into a portion of the polar fluid. Fluid splitting structure assisted movement of the non-polar fluid splits the polar fluid.

A method of manufacturing a three-dimensional electrochemical lithium battery includes forming a first electrode on an underlying layer comprising aerosolizing a first ink formulation comprising a slurry including nanoparticles or microparticles of a first active material and a binder, and depositing the slurry onto the underlying layer to form a first electrode layer. A permeable separator layer is formed on the first electrode by aerosolizing a polymer precursor solution, exposing the aerosolized polymer precursor solution to a first activating radiation source to form partially cured polymer spheres in the aerosolized stream, focusing and directing the aerosolized stream onto a substrate to form the permeable separator layer of the partially cured polymer spheres, and exposing the partially cured polymer spheres on the substrate to a second activating radiation source to fully cure the partially cured polymer spheres. A second electrode is formed on the permeable separator layer by aerosolizing a second ink formulation comprising a slurry including nanoparticles or microparticles of a second active material and a binder, and depositing the slurry onto the permeable separator layer. 1. A method of manufacturing a three-dimensional electrochemical lithium battery , the method comprising:forming a first electrode on an underlying layer comprising aerosolizing a first ink formulation comprising a slurry including nanoparticles or microparticles of a first active material and a binder, and depositing the slurry onto the underlying layer to form a first electrode layer;forming a permeable separator layer on the first electrode comprising aerosolizing a polymer precursor solution, exposing the aerosolized polymer precursor solution to a first activating radiation source to form partially cured polymer spheres in the aerosolized stream, focusing and directing the aerosolized stream onto a substrate to form the permeable separator layer of the partially cured polymer ...

A device (12-16) and method of making and using the same. The device (12-16) includes first and second substrates (22-26, 32-36) that are spaced to define a fluid space. Polar and non-polar fluids (212-215, 222-225) occupy the fluid space. A first electrode (122- 126), with a dielectric layer (92-96), is positioned on the first substrate (22-26) and electrically coupled to at least one voltage source (522-526), which is configured to supply an electrical bias to the first electrode (122-126). The fluid space includes at least one fluid splitting structure (52-56) that is configured to facilitate the movement of the non-polar fluid (222-225) into a portion of the polar fluid (212-215). Fluid splitting structure assisted movement of the non-polar fluid (222-225) splits the polar fluid (212-215).
