  • Patent number: 11905302
    Abstract: The present disclosure relates to a prelithiation solution and a method for preparing a prelithiated anode using the same. The prelithiation solution and the method for preparing a prelithiated anode using the same according to the present disclosure allow uniform intercalation of lithium ions throughout the anode chemically in a solution via a simple process of immersing the anode in a prelithiation solution having a sufficiently low redox potential as compared to an anode active material. A prelithiated anode prepared by this method has an ideal initial coulombic efficiency and a lithium secondary battery with a high energy density can be prepared based thereon. In addition, the prepared anode is advantageously applicable to large-scale production due to superior stability even in dry air.

  • Patent number: 11821733
    Abstract: A terrain referenced navigation system for a vehicle is disclosed and includes an inertial measurement unit and one or more generic terrain sensors configured to collect terrain-dependent data. The terrain referenced navigation system includes one or more processors in electronic communication with the generic terrain sensors and the inertial measurement unit, and a memory coupled to the processors. The memory stores data into one or more databases and program code that, when executed by the processors, causes the terrain referenced navigation system to determine a predicted terrain value based on a terrain value, where the terrain value is retrieved from one or more sensor specific terrain databases. The pre-Kalman filter processing values are sent to a Kalman filter. The Kalman filter determines navigation corrections and sensor corrections based on the pre-Kalman filter processing values.
