Split Test Cell with Beryllium (Be) Window for In-situ XRD & XAS of Battery Electrode - EQ-STC-BEW

EQ-STC-BEW split-able test cell features a 35 mm Dia. Beryllium (Be) Window which allows in-situ XRD analysis of battery material phase transitions during the charging/discharging cycles. Such a cell can accommodate various sizes (19, 20, and 24 mm diameter) of electrodes and separators. It is designed for easy&quick assembling tests of the electrode materials of rechargeable batteries.

MTI has granted the patent 2016205216261 for the Split Test Cell with Beryllium (Be) Window for In-situ XRD Analysis - EQ-STC-BEW since June 2016.

SPECIFICATIONS:

Features	Featured a Beryllium (Be) Window which is nearly transparent to X-rays. Such window is also electrically conductive and thus allows XRD in-situ analysis for electrode materials during cell charging/discharging cycles or under various temperature conditions A free stand is included for the proper height adjustment of the split cell in order to fit the best testing position. Please click the image on the left for details.

Assembly Instruction
Application Notes	For In-situ Laser Raman Spectroscopy, the typical wavelength used is ranging from ultra-violet (244 nm~364 nm) to near-infrared (785 nm~1064 nm). The Be observation window we used is nearly transparent in this wavelength range For better in-situ observation, electrode material shall face the window.  you may use lab press and dry pressing die below to prepare an electrode pellet instead of using electrode coated Al or Cu foil Optional: Purchase a vacuum pen for easy component placement
