  • Patent number: 10862494
    Abstract: A background offset drift calibration circuit and method for comparator are proposed. The background calibration circuit and method are designed based on the approximate linear characteristic of the offset drift of a comparator caused by the variation of temperature and power supply. The calibration circuit for the comparators obtains the offset drift characteristic of each comparator by performing twice foreground calibration and selects the comparator with the largest drift as the reference comparator and other comparators as working comparators. The reference comparator is configured to track the offset drift and trigger the background calibration circuit of other working comparators. The working comparators compensate for the offset drift caused by the temperature or the power supply in the background by linear interpolation based on the offset drift characteristic of each comparator.

In one embodiment, opposing electrodes are formed with like lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. In another embodiment, a battery electrode material is applied to one side of a current collector and capacitor material is applied to the other side. In general, the electrodes are formed by combining a suitable grouping of capacitor layers with un-equal numbers of anode and cathode battery layers. One or more pairs of opposing electrodes are assembled to provide a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells may be formed by stacking or winding rolls of the opposing electrodes with interposed separators.

Or one or both of the anode current collector and cathode current collectors of a heating cell may be formed with shaped extended portions, uncoated with electrode materials, through which cell current may be passed for resistance heating of the extended current collector areas. These extended current collector areas may be used to heat the working area of the cell in which they are incorporated, or to contact and heat an adjacent working cell.

  • Publication number: 20200173028
    Abstract: A copper foil, intended for use as a current collector in a lithium-containing electrode for a lithium-based electrochemical cell, is subjected to a series of chemical oxidation and reduction processing steps to form a field of integral copper wires extending outwardly from the surfaces of the current collector (and from the copper content of the foil) to be coated with a resin-bonded porous layer of particles of active electrode material. The copper wires serve to anchor thicker layers of porous electrode material and enhance liquid electrolyte contact with the electrode particles and the current collector to improve the energy output of the cell and its useful life.

  • Publication number: 20200075016
    Abstract: A network computer system for managing a network service (e.g., a transport service) can include a voice-assistant subsystem for generating dialogues and performing actions for service providers of the network service. The network computer system can receive, from a user device, a request for the network service. In response, the network computer system can identify a service provider and transmit an invitation to the provider device of the service provider. In response to the identification of the service provider for the request, the voice-assistant subsystem can trigger an audio voice prompt to be presented on the provider device and a listening period during which the provider device monitors for an audio input from the service provider. Based on the audio input captured by the provider device, the network computer system can determine an intent corresponding to whether the service provider accepts or declines the invitation.

  • Publication number: 20190372127
    Abstract: A hybrid lithium-ion battery/capacitor cell comprising at least a pair of graphite anodes assembled with a lithium compound cathode and an activated carbon capacitor electrode can provide useful power performance properties and low temperature properties required for many power utilizing applications. The graphite anodes are formed of porous layers of graphite particles bonded to at least one side of current collector foils which face opposite sides of the activated carbon capacitor. The porous graphite particles are pre-lithiated to form a solid electrolyte interface on the anode particles before the anodes are assembled in the hybrid cell. The pre-lithiation step is conducted to circumvent the irreversible reactions in the formation of a solid electrolyte interface (SEI) and preserve the lithium content of the electrolyte and lithium cathode during formation cycling of the assembled hybrid cell. The pre-lithiation step is also applicable to other anode materials that benefit from such pre-lithiation.

  • Publication number: 20190341648
    Abstract: Lithium-utilizing electrochemical cells, providing hybrid battery and capacitor activity, are formed of one or more lithium battery anodes, one or more lithium battery cathodes, and with at least one capacitor electrode in the cell, with an equal number of electrodes with opposing charges. The respective electrodes are formed of porous layers of one of lithium anode material particles, lithium cathode material particles, or compatible capacitor material particles, formed on both sides of a compatible current collector foil. The capacity and durability of the hybrid cell is enhanced when through-holes are formed through selected electrodes, or through the current collector foils of selected electrodes, to enhance the flow of a non-aqueous liquid electrolyte solution, with its lithium cations and associated anions, to reach both sides of the closely spaced, separated, electrodes in an assembled and operating lithium battery/capacitor hybrid cell.
