摘要： Embodiments of the invention relate to energy storage devices, e.g., capacitors and batteries, that may include a composite article of elongated conductive structures embedded in a polymer matrix. In some embodiments, a liquid containing ionic species may be dispersed within the polymer matrix of the article. The liquid may contact the elongated conductive structures within the polymer matrix. When the composite article is used as an energy storage device, the large surface area at the interface between the elongated conductive structures and the liquid can provide high energy storage. Embodiments of the invention enable storing energy using a composite article that exhibits both high and low temperature stability, high cyclic repeatability, and mechanical flexibility. The composite article can also be non-toxic, biocompatible and environmentally friendly. Thus, the composite article may be useful for a variety of energy storage applications, such as in the automotive, RFID, MEMS and medical fields.

摘要： Metal/metal oxide nanoparticle-embedded polymer films were synthesized in situ wherein the polymerizing agent was utilized for both reduction and polymerization (such as curing). This in situ method avoids the use of any external reducing agent/stabilizing agent and leads to a uniform distribution of nanoparticles in the polymer matrix. In some embodiments, additional heating can be utilized to form the nanoparticles embedded in the polymer film.

摘要： A solid electrolyte is formed by blending a coating chemical with metal ions and fatty acid. Filling molds and drying the material in the molds forms the solid electrolyte. The solid electrolyte is mounted on an electrode and attached to a handle. The solid electrolyte is moved over a surface of a substrate with the handle. DC current is passed between the electrode and substrate and ions are transferred to the wetted substrate from the solid electrolyte.

摘要： Additive manufacturing includes successively forming a plurality of layers on a support. Depositing a layer from the plurality of layers includes dispensing first particles, selectively dispensing second particles in selected regions corresponding to a surface of the object, and fusing at least a portion of the layer. The layer has the first particles throughout and the second particles in the selected regions. Alternatively or in addition, forming the plurality of layers includes depositing multiple groups of layers. Depositing a group of layers includes, for each layer in the group of layers dispensing a feed material to provide the layer, and after dispensing the feed material and before dispensing a subsequent layer fusing a selected portion of the layer. After all layers in the group of layers are dispensed, a volume of the group of layers that extends through all the layers in the group of layers is fused.
