Publication number: US20220181598A1
Application number: 17/543,160

Abstract:
The present disclosure relates to a solid-state electrochemical cell having a uniformly distributed solid-state electrolyte and methods of fabrication relating thereto. The method may include forming a plurality of apertures within the one or more solid-state electrodes; impregnating the one or more solid-state electrodes with a solid-state electrolyte precursor solution so as to fill the plurality of apertures and any other void or pores within the one or more electrodes with the solid-state electrolyte precursor solution; and heating the one or more electrodes so as to solidify the solid-state electrolyte precursor solution and to form the distributed solid-state electrolyte.

Publication number: US20220089042A1
Application number: 17/542,714

Abstract:
A method for operating an advanced driver assistance (ADAS) system of a motor vehicle includes a vehicle controller receiving, from side and end cameras mounted to the vehicle, camera signals indicative of real-time images of outboard-facing side and end views of the vehicle. The controller determines a region of interest (ROI) inset within each end/side view within which is expected foreign objects and/or hazards. These ROIs are analyzed to detect if a foreign object/hazard is present in the vehicle's end and/or side views. Responsive to detecting the foreign object/hazard, movement of the foreign object/hazard is tracked to determine if the foreign object/hazard moves towards or away from the vehicle's underbody region. If the foreign object/hazard moves to the underbody region, control signals are transmitted to the vehicle's propulsion and/or steering system to automate preventative action that prevents collision of the vehicle with and/or removes the foreign object/hazard from the underbody.

Publication number: US20220181629A1
Application number: 17/542,147

Abstract:
The present disclosure relates to an electrochemical cell having an elastic binding polymer that improves long-term performance of the electrochemical cell, particularly when the electrochemical cell includes an electroactive material that undergoes volumetric expansion and contraction during cycling of the electrochemical cell (such as, silicon-containing electroactive materials). The electrochemical cell can include the elastic binding polymer as an electrode additive and/or a coating layer disposed adjacent to an exposed surface of an electrode that includes an electroactive material that undergoes volumetric expansion and contraction and/or a gel layer disposed adjacent to an electrode that includes an electroactive material that undergoes volumetric expansion and contraction. The elastic binding polymer may include one or more alginates or alginate derivatives and at least one crosslinker.
