Abstract: An anode for an energy storage device is provided that includes a current collector having an electrically conductive layer, a plurality of lithium storage filamentary structures in contact with the electrically conductive layer. For each lithium storage filamentary structure of the plurality of lithium storage filamentary structures, there is a first supplemental layer overlaying at least a portion of the respective filamentary structure, the first supplemental layer including silicon nitride or a first metal compound. There is further a second supplemental layer overlaying at least a portion of the first supplemental layer, the second supplemental layer having a composition different from the first supplemental layer and comprising silicon nitride or a second metal compound.

Abstract: An anode for an energy storage device includes a current collector having an electrically conductive layer, a first surface characterized by a first pattern, and a second surface characterized by a complementary second pattern. The anode further includes a patterned lithium storage structure comprising a continuous porous lithium storage layer disposed over the current collector in a pattern corresponding to the first pattern. A method of making an anode for use in an energy storage device includes providing a current collector having an electrically conductive layer, a first surface characterized by a first pattern, and a second surface characterized by a complementary second pattern. A continuous porous lithium storage layer is formed by chemical vapor deposition over the first surface by exposing the current collector to a lithium storage material precursor gas.

Abstract: A lithium-ion battery may include a cathode, an anode, and a polymer electrolyte. The anode may include a current collector. A patterned lithium storage structure may overlay a patterned current collector. The patterned lithium storage structure may include first regions of a lithium storage material characterized by a first pattern. The patterned current collector may include second regions of recessed portions characterized by a second pattern complementary to the first pattern. The lithium storage material may include at least 40 atomic % amorphous silicon. These and other anodes and lithium-ion batteries are described.

Abstract: An anode for an energy storage device includes a current collector having a metal oxide layer. A continuous porous lithium storage layer overlays the metal oxide layer, and a first supplemental layer overlays the continuous porous lithium storage layer. The continuous porous lithium storage layer may be substantially free of nanostructures. The continuous lithium storage layer may include amorphous silicon deposited by a PECVD process. The first supplemental layer includes silicon nitride, silicon dioxide, or silicon oxynitride. The anode may further include a second supplemental layer overlaying the first supplemental layer.

Abstract: This invention is an acoustic fiber-based substrate composed primarily of insulation-type spun fibers or blends of such fibers and wheel spun fibers. The fibers are bound with a water-dispersible latex binder, or an agri-binder such as starch in conjunction with cellulose fiber. The insulation-type spun fibers can be first quality virgin, post-industrial waste-stream or post-consumer waste stream fiber. The substrate is wet-formed from a very dilute aqueous dispersion of ingredients onto a mesh forming screen, as on a Fourdrinier paper machine. By virtue of the insulation-type spun fiber dimensions, morphology and orientation: very low density wet-mats can be formed from a sufficiently dilute suspension. With respect to other wet-formed substrates, the invention is much lower in density and more highly porous, and, thus, the substrate is highly absorbing, exhibiting noise reduction coefficients, NRC values of about 0.80 or greater.

The mineral fibers comprise from about 50% to about 85%, the perlite includes from 0% to about 18%, the cellulosic fiber comprises from about 2% to about 7% and the binder includes from about 6% to about 15% of the panel on a dry solids weight basis. The concentration of mineral fibers includes from about 30% to about 65% nodulated mineral fiber. The perlite has a density in the range from about 7 to about 20 pcf.

Abstract: Phosphate reactive sheets and substrates can be prepared using wet-laying and dry-laying techniques. The wet or dry-laid composition contains calcium silicate and a non-reactive matrix of either fiber or a mixture of fiber and a binder. The matrix is used in an amount effective to hold the wet or dry-laid material together. At a desired time such phosphate reactive substrate compositions can be contacted with aqueous solutions of phosphoric acid. A metal oxide selected from aluminum oxide, magnesium oxide, zinc oxide, and calcium oxide must be present in either the substrate, the solution, or both. After the solution contacts the substrate, a reaction takes place within the matrix to form a rigid article.

Abstract: Processes are described for producing strong, durable fiberous phosphate ceramic structures. Stronger fiberous phosphate ceramic structures can be produced by applying higher pressures during the reaction of phosphoric acid, a metal oxide selected from the group consisting of zinc oxide, calcium oxide, magnesium oxide, and aluminum oxide; and calcium silicate within a matrix of the fiber, or the fiber and a binder.
