EQ-STC-PQW split test cell is made of PEEK (Poly Ether Ether Ketone) plastic and designed for R&D of rechargeable battery material. Quartz Window with a 38.1mm Dia. on the top allows the optical microscope head touch window for in-situ analysis of battery electrode microstructure change or dendrite growth during charging and discharging. Such a cell can be used for different kinds of electrodes and separators and test the electrodes easily and quickly.

SPECIFICATIONS:

Cell Material	PEEK (Poly Ether Ether Ketone), which is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures.
Features	Sealed by electrolyte corrosive-proof FKM O-rings. Small enough to be put in and taken out from a glove box. Easy to separate and clean after testing. Use an optical microscope to see in-situ dendrite growth
Quartz Observation Window	Diameter = 38.1mm Thickness = 1.00 mm

Application Notes	For better in-situ observation, electrode material shall face the window.  you may use lab press and dry pressing dies below to prepare an electrode pellet instead of using electrode coated Al or Cu foil. Optional: Purchase a vacuum pen for easy component placement.      PEEK VS. TEFLON PTFE/FEP MACHINING
