Small Split Cell with Quartz Window for In-Situ Optical Microscope Analysis of SSB Interface - EQ-STC-SSI


In stock
Item Number: STC-SSI

EQ-STC-SSI-S is a small splittable test cell with optical grade quartz widow to analyze the interface of solid-state battery electrodes, mainly dendrite growth,  via an optical microscope. 
Two small plates driven by screws would press the cathode, solid electrolyte, and anode electrode together.

SPECIFICATIONS:

Test Cell
  • The cell case is made of Nylon
  • Sealed by the silicone O-rings which is liquid-tight and air-tight
  • Two pressing plates are made of stainless steel 304 with the gold coating
  • Two brass pressing screws for Cathode ad Anode
  • Max Force:  1500N 
  • Note:  May use a digital torque wrench to apply force accurately.
