The first and second layers are positioned adjacent each other with their first surfaces facing inward toward each other and separated by a gap distance. An electric potential is generated upon movement between the first and second flexible layers, such as at least alternating contact and no-contact between the first and second flexible layers. The electron donating material may be provided by a particle-free conductive ink.

A method for creating a dielectric thin-film coating for devices having a fusible element is disclosed. The method comprises mixing insoluble and soluble polymers in solid form and exposing the mixture to heat to create a melt mixture. The melt mixture is then dissolved in a solvent to create a slurry which can then be deposited on the device as a thin-film coating to create an interior insulation layer or an external surface.

[Problem] To lower electrical resistance by increasing the interfacial surface area and the adhesion between a current collector and an active material or an electrolyte, or between the active material and the electrolyte in an all-solid-state battery. In addition, to improve battery performance by eliminating or minimizing residual carbon originating from a binder. [Solution] According to the present invention, a slurry, composed of an electrode active material and a solvent, and a slurry, composed of electrolyte particles and a solvent, can be impacted against a target and thereby attached thereto to form a high-density layer and improve adhesion. Moreover, residual carbon is eliminated or minimized by eliminating or minimizing the content of binders, thereby improving battery performance.

A composite article includes a lightning strike protection coating on a composite substrate. The lightning strike protection coating is formed from electrically conductive material and includes protrusions spaced along the length and width of a portion of the substrate surface. To form the lightning strike protection coating, a form is pressed against electrically conductive coating material on the composite substrate while the electrically conductive coating material is flowable. For example, the form can be a release film used in a composite vacuum bagging process. Suitable release film can have depressions along an inner surface that define an imprint of the coating protrusions. After curing, the coating can be covered with a layer of paint that conceals the protrusions but still allows lightning streamers to penetrate the paint at the protrusions.
