Abstract: Described are substrates including a layer of an aluminum alloy with a conductive coating, also referred to as a protective overlayer. The conductive coating can prevent certain material from coming into contact with the aluminum alloy layer while allowing transmission of electrons to the aluminum alloy. The substrates may be used, for example, in electronics applications, such as current collectors or electrodes for batteries, electrochemical cells, capacitors, supercapacitors, or the like.

Abstract: Described are composites having at least one layer, the at least one layer including an alloy of Al and at least another component or at least one layer including a first and second pluralities of particles. The first plurality of particles may be selected from at least one of Al particles and Al alloy particles. The second plurality of particles may be selected from at least one of metal particles and non-metal particles, wherein the metal particles are selected from at least one of zinc, silicon, bismuth, copper, germanium, indium, antimony, tin, magnesium, or combinations thereof, and the non-metal particles are selected from at least one of carbon, lithium titanium oxide, titania, MoO, MoS2, Co2O4, MnO2, Fe2O3, Fe3O4, FeS, CuO, or combinations thereof. The composites may be used as both current collectors and active material.

Abstract: Multi-terminal capacitor devices and methods of making multi-terminal capacitor devices are described herein. The multi-terminal capacitor devices may include a plurality of individual capacitors arranged in a single device layer, such as high surface area capacitors. A individual capacitor may include an aluminum foil-based electrode, an aluminum oxide dielectric layer conformal with the aluminum foil-based electrode, and a conductive material electrode, such as a conducting polymer or a conductive ceramic, in conformal contact with the dielectric layer.

Abstract: Disclosed is a metal foil capacitor, preferably an aluminum capacitor, comprising a modified metal foil comprising a base metal, preferably an aluminum foil. The modified metal foil capacitor may satisfy at least two of the following conditions: (a) the modified metal foil has a surface area of at least 10 times greater than an unmodified metal foil; (b) the modified metal foil has a dielectric constant (k) of at least 5; (c) the modified metal foil has a thickness of at least 1 micron; and/or (d) the modified metal foil comprises at least one metal in addition to the base metal, wherein the at least one metal is present in an amount of at least 0.01 wt.% based on the total weight of the modified metal foil. Methods for preparing the metal foil capacitor are also disclosed.
