  • Patent number: 11024842
    Abstract: An anode for an energy storage device includes a current collector having a metal layer; and a metal oxide layer provided in a first pattern overlaying the metal layer. The anode further includes a patterned lithium storage structure having a continuous porous lithium storage layer selectively overlaying at least a portion of the first pattern of metal oxide. A method of making an anode for use in an energy storage device includes providing a current collector having a metal layer and a metal oxide layer provided in a first pattern overlaying the metal layer. A continuous porous lithium storage layer is selectively formed by chemical vapor deposition by exposing the current collector to at least one lithium storage material precursor gas.

  • Publication number: 20210119217
    Abstract: An anode for a lithium-based energy storage device such as a lithium-ion battery is disclosed. The anode includes an electrically conductive current collector comprising an electrically conductive layer and a transition metal oxide layer overlaying the electrically conductive layer. The anode may include a continuous porous lithium storage layer provided over the transition metal oxide layer. The continuous porous lithium storage layer may include at least 40 atomic % silicon. A method of making the anode may include providing an electrically conductive current collector having an electrically conductive layer and a transition metal oxide layer provided over the electrically conductive layer. The transition metal oxide layer may have an average thickness of at least 0.05 ?m. A continuous porous lithium storage layer is deposited over the transition metal oxide layer by PECVD.

  • Publication number: 20210057733
    Abstract: An anode for an energy storage device such as a lithium-ion energy storage device is disclosed. The anode includes a current collector having a metal oxide layer, a first lithium storage layer overlaying the current collector, a first intermediate layer overlaying at least a portion of the first lithium storage layer, and a second lithium storage layer overlaying the first intermediate layer. The first lithium storage layer is a continuous porous lithium storage layer having a total content of silicon, germanium, or a combination thereof, of at least 40 atomic %.

  • Publication number: 20210050584
    Abstract: A method of making an anode for use in an energy storage device includes providing a current collector having an electrically conductive layer and a metal oxide layer overlaying over the electrically conductive layer. The metal oxide layer has an average thickness of at least 0.01 ?m. A continuous porous lithium storage layer is deposited onto the metal oxide layer by a CVD process. The anode is thermally treated after deposition of the continuous porous lithium storage layer is complete and prior to battery assembly. The thermal treatment includes heating the anode to a temperature in a range of 100° C. to 600° C. for a time period in a range of 0.1 min to 120 min. 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.

  • Publication number: 20210050593
    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 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.

  • Publication number: 20210050591
    Abstract: 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 ?m. 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.
