  • Patent number: 11309585
    Abstract: An interfacial additive layer for decreasing the interfacial resistance/impedance of a silicon based electrode-containing device such as, for example, an energy storage device or a micro-resistor, is disclosed. The interfacial additive layer, which is composed of a molten lithium containing salt, is formed between a silicon based electrode and a solid polymer electrolyte layer of the device. The presence of such an interfacial additive layer increases the ion and electron mobile dependent performances at the silicon based electrode interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device.

  • Publication number: 20220052316
    Abstract: A silicon-based electrode forms an interface with a layer pair being: 1. a thin, semi-dielectric layer made of a lithium (Li) compound, e.g. lithium fluoride, LiF, disposed on and adheres to the electrode surface of the silicon-based electrode and 2. an molten-ion conductive layer of a lithium containing salt (lithium salt layer) disposed on the semi-dielectric layer. One or more device layers can be disposed on the layer pair to make devices such as energy storage devices, like batteries. The interface has a low resistivity that reduces the energy losses and generated heat of the devices.

  • Patent number: 11245134
    Abstract: A Lithium energy storage device comprising a cathode, electrolyte, anode, and substrate. The materials contained in the anode and electrolyte region are electrochemically altered during initial formation and exposed to current cycles to create a lower impedance composite anode. The resulting composite anode bottom is a bi-layer comprising: i. a lithium metal layer and ii. a silicon-based interphase layer. The bi-layer acts as a barrier to inhibit Lithium ions from entering or leaving a Lithium saturated substrate, once the interphase surface is formed and the substrate is saturated with Lithium ions. This prevents cell failure from large volume changes/stresses during charge/discharge cycles and enables a significant decrease in cell impedance to enable better rechargeable cell performance.

  • Patent number: 11205800
    Abstract: A device such as, for example, an energy storage device or a micro-resistor, is disclosed which includes a silicon based electrode in which decreased interfacial resistance/impedance throughout the charge-mobile region of the device is provided. The decreased interfacial resistance/impedance is provided by forming an interfacial additive composite layer composed of a molten lithium containing salt layer and a layer of a Li-salt containing conductive polymeric adhesive material between the silicon based electrode and a solid polymer electrolyte layer. The presence of such an interfacial additive composite layer increases the ion and electron mobile dependent performances at the silicon based electrode interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device.
