  • Patent number: 10273593
    Abstract: An electrochemical cell that allows for in-situ structural characterization of amorphous thin film materials during the course of electrolysis using high-energy X-ray scattering (>50 keV). The compact and versatile cell employs a three-electrode configuration and minimizes X-ray scattering contributions from the cell, reference and counter electrodes, as well as the working electrode support. A large surface area working electrode has a physically robust support and is largely transparent to X-rays. This design, which utilizes a three-dimensional working electrode, also greatly improves the intensity and quality of the scattered signal compared to a two-dimensional working electrode. The in-situ cell can be used not only to investigate structural evolution during electrolysis using X-ray scattering (e.g. pair distribution function), but also to perform electrochemical potential-dependent structural analysis by extended X-ray absorption fine structure.

  • Patent number: 9140660
    Abstract: A method for preventing the formation of gas bubbles inside a high pressure reference electrode in the electrolyte-filled section, and thus eliminating the gas bobble effect on the electrical continuity, was disclosed. One or more thin solid rods or tubes are inserted into the internal electrolyte-housing tube and the thin rods or tubes alter the surface tension of the gas bubbles so that the bubbles are unstable in the middle of the liquid electrolyte. Compared with the fiber wicks or porous powder used by previous researchers to ensure the electrical continuity, the thin tubes or rods are easy to handle and easy to clean. This method may also be used in other systems that contain a liquid-filled vertical or sloped tube (e.g., a pH electrode) to prevent the formation of gas bubbles in the liquid-filled section of the tube.
