Split Test Cell with Quartz Window for Battery Electrode In-situ Analysis: Optional Insert Size & Au Coating - EQ-STC-QW


Product Options

Inserts Size:

Personalization

EQ-STC-QW split-able test cell is designed for R&D of rechargeable battery material. A 16.8 mm Dia. quartz window on its bottom allows in-situ X-Ray analysis of battery material phase transition during charging and discharging. Such a cell can accept various sizes (19, 20, and 24 mm diameter) of electrodes and separators and test the electrodes easily and quickly.

SPECIFICATIONS:

Structure
  • Full stainless steel
Features
  
  • Electrolyte corrosive-proof PTFE Guide Sleeve capable of withstanding up to 250 ºC. (19, 20, and 24 mm diam. are available. Please select the size at option bar.
  • Sealed by electrolyte corrosive-proof PTFE O-rings.
  • A 6 mm height spacer inside the test cell to press down on the electrode and prevent the electrode from curling.
  • Small enough to be put in and taken out from a glove box.
  • Easy to separate and clean after testing.
  • Same functionality to "Swagelok Coin Cell" but with more size options for electrode and separator and also the proper dimensions for glove box compatibility.
Quartz Observation Window

  • Observation Area = 2.0 mm Dia. Quartz Observation Window allows the X-Ray beam penetration
  • Customized split cell with enlarged observation area up to 8.0 mm Dia. is available at extra cost (See picture below)
  • Quartz Window Size = 16.8 mm Dia. 
  • Thickness = 1.92 mm
  • Recessed Spacing = 6.00 mm
          
Max. Working Temperature
  • 250 ºC
Optional

  • Please select the insert size in the option bar. 10, 12, 15, 19, 20, and 24 mm diameter inserts are available.
  • Anti-corrosive Au coating on the cell internal and inserts is an option. $396 surcharge will apply.
Max. Cell Thickness Cathode+separator+anode: 6mm

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 quartz observation window we used can provide  >80% light-throughput for 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.
