Abstract: A method of fabricating an electrode is provided. The method includes adding one or more dry powders to an extruder barrel of an extruder at a first location, adding one or more solvents to the extruder barrel at a second location that is downstream of the first location to form a material mixture, applying a mixing force to the material mixture to form a paste, and extruding the paste as a continuous film onto one or more surfaces of a current collector to form the electrode. The one or more dry powders include an electroactive material. The paste is a homogeneous semi-solid having a solids content greater than or equal to about 60% to less than or equal to about 90%. The continuous film has a thickness greater than or equal to about 50 μm to less than or equal to about 500 μm.

Abstract: A longitudinal vehicle speed sensor for a vehicle includes a first sensor configured to generate a first measured speed based on one of a wheel speed of the vehicle receiving output torque from a drive unit and an output of a global positioning system (GPS). A second sensor is configured to generate a second measured speed. A speed weighting module is configured to apply a first weight to the first measured speed to generate a first weighted speed. A speed weighting module is configured to apply a second weight to the second measured speed to generate a second weighted speed. An output module is configured to generate a speed estimate based on the first weighted speed and the second weighted speed.
