Abstract: An anode for an energy storage device may include a current collector. An anode may include a first lithium storage layer overlaying the current collector. An anode may include a first intermediate layer overlaying at least a portion of the first lithium storage layer. An anode may include a second lithium storage layer overlaying the first intermediate layer. The first lithium storage layer may be a continuous porous lithium storage layer including a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %. The first intermediate layer may include a first sublayer in contact with an underlying lithium storage layer and a second sublayer overlaying the first sublayer and in contact with an overlying lithium storage layer, the first sublayer having different a chemical composition than the second sublayer.

Abstract: A method of making an anode for an energy storage device such as a lithium-ion energy storage device is disclosed. The method may include depositing a first lithium storage layer over a current collector by a first CVD process. The current collector may include a metal oxide layer, and the first lithium storage layer is deposited onto the metal oxide layer. The method may also include forming a first intermediate layer over at least a portion of the first lithium storage layer. The method may further include depositing a second lithium storage layer over the first intermediate layer by a second CVD process. At least the first lithium storage layer may be a continuous porous lithium storage layer having a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %.

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.

Abstract: A fine texture fiberboard panel having a low resistivity value and a high board hardness value. The panel includes mineral fibers, perlite, cellulosic fibers, and binder. 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.
