摘要： 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 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. The second supplemental layer has a composition different from the first supplemental layer and may include silicon dioxide, silicon nitride, silicon oxynitride, or a metal compound.

摘要： An anode for an energy storage device includes a current collector having an electrically conductive layer that includes nickel or copper, and a lithium storage structure comprising a plurality of first microstructures in contact with the electrically conductive layer. Each first microstructure includes silicon and is characterized by a first maximum width measured across the widest section orthogonal to the first microstructure axis. Each first microstructure includes a first portion characterized by the width substantially tapering from the maximum width to a location where each first microstructure contacts the electrically conductive layer and a second portion positioned farther from the electrically conductive layer than the first portion, the second portion defining a substantially hemispherical shape and the top of each first microstructure. The lithium storage structure has at least 1 mg/cm2 of active silicon and a total atomic % of nickel and copper is from 0.5% to 1.2%.

摘要： A method of making a prelithiated anode for use in a lithium-ion battery includes providing a current collector having an electrically conductive layer and a metal oxide layer overlaying the electrically conductive layer. The metal oxide layer has an average thickness of at least 0.01 μm. A continuous porous lithium storage layer is deposited onto the metal oxide layer by a CVD process. Lithium is incorporated into the continuous porous lithium storage layer to form a lithiated storage layer prior to a first electrochemical cycle when the anode is assembled into the battery. The anode may be incorporated into a lithium ion battery along with a cathode. The cathode may include sulfur or selenium and the anode may be prelithiated.

摘要： The present invention is particularly directed to graphenic dispersion and slurry compositions and the production and uses thereof, where these compositions exhibit one or more of the hallmark strength, thermal or electrical properties of “pure” graphene while at the same time being optimized in terms of solubility or other properties necessary for compatibility with one or more end processes. In specific embodiments, a composition of matter includes a graphenic mixture and at least one species of polymerized product of benzyl alcohol, and a method of making such composition of matter comprises sonicating the graphenic mixture in heated benzyl alcohol. In a further specific embodiment, a composition of matter is formed by sonicating a graphenic mixture in heated benzyl alcohol, wherein the resulting composition exhibits a binder functionality in the absence of exogenous binder.
