Abstract: A fixture assembly for testing or measuring a portion of a battery electrode includes a top plate, a baseplate, a connector and a support member. The top plate includes holes for creating a low-pressure region along a top surface of the top plate to hold the portion of the battery electrode to the top plate. The baseplate includes a bottom plate and side walls. The side walls extend upward from the bottom plate and define a vacuum chamber with the top plate. The connector is attached to the baseplate and configured to be connected to a vacuum hose for drawing air from the vacuum chamber to pull the portion of the battery electrode to the top plate. The support member is attached to the baseplate and configured to hold the fixture assembly in place relative to a measuring device that measures a physical characteristic of the battery electrode.
