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.
