EQ-STC-BEW Introduction EQ-STC-BEW split-able test cell features a 40mm Dia. Beryllium (Be) Window which allows in-situ X-Ray analysis of battery material phase transitions during charging/discharging cycles. Such a cell can accommodate various sizes (15, 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.

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 stands is included for the proper height adjustment of the split cell in order to fit the best testing position. (430mm to 480mm height adjustable)

• Electrolyte corrosive-proof PTFE Guide Sleeve capable of withstanding up to 250℃.

• Sealed be electrolyte corrosion-resistant PTFE O-rings. • Slim design allows the operation inside of the glove box. • Easy to assemble, separate or clean after the completion of each experiment. • Same functionality as “Swagelok Coin Cell” but more size options for

electrodes. Components & Materials

• Stainless Steel constructed body and pressing plate • Beryllium (Be) window

Dimension • Height: 62mm min. without load • Diameter: 75mm (widest diameter without lead) • Lead-exposed length: 19mm • Beryllium (Be) Window: 40mm Dia. X 1.5mm thickness

Be Observation Window

• Beryllium (Be) Observation Window allows the X-Ray beam penetration. • XRD diffraction angle (2θ) 25°~ 155°(For the measurement of diffraction

peaks beyond this range, please contact engineer for more details) • Diffraction pattern of SiO2 (10-10) • A typical setup of split test cell with XRD device

Max. Working Temperature

• 250℃

PTFE Sleeve Size Option

• PTFE Sleeve around a stainless steel pressing pad • PTFE sleeve I.D.: 15,19,20 and 24 mm • PTFE sleeve O.D.: 29 mm



EQ-STC-BEW Max. Cell Thickness • Cathode + Separator + Anode: 5mm 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.

Precaution 1. In order to prevent electrolyte leakage, please tighten the screw cap on the top after electrolyte injection.

2.Adjust the cylinder spring pressure according to the cell’s thickness:

• Unscrew and remove the screw cap. (pic. 1) • Adjust the spring height to desired position with a flat head screw driver. (pic. 2) • Reinstall the screw cap and tighten it before use.
