Electrode test fixture and system for material characterization and standardization

Electrode test fixture devices and systems for material characterization and standardization are provided. A fixture assembly for testing or measuring a portion of a battery electrode includes a top plate, a bottom plate, a connector, and a support member. The top plate includes an aperture for creating a low pressure region along a top surface of the top plate to retain a portion of the battery electrode to the top plate. The substrate comprises a bottom plate and a side wall. The side wall extends upwardly from the bottom plate and defines a vacuum chamber with the top plate. A connector is attached to the bottom plate and is configured to be connected to a vacuum hose for extracting air from the vacuum chamber to pull a portion of the battery electrode to the top plate. A support member is attached to the substrate and is configured to hold the fixture assembly in place relative to a measurement apparatus that measures a physical characteristic of the battery electrode. 提供了用于材料表征和标准化的电极测试固定装置和系统。一种用于测试或测量电
