Test cell for optical and X-ray characterization in the reflective mode with face-to-face arrangement of electrodes

Product overview

Product description

The ECC-Opto-Std test cell is dedicated to the inspection of electrodes by optical methods such as light microscopy or Raman spectroscopy working in the reflection mode. Basically, the respective instrument looks through a transparent window onto the backside of the working electrode. For this purpose the working electrode is to be supported on a perforated current collector or a current collector having a single small hole in its center. Different versions are available for use in either aprotic or aqueous electrolytes and can be adapted to the optical instrumentation used.

Frequently asked questions

Can I use the provided borosilicate glass window with any lithium battery electrodes?

Borosilicate glass is a good choice for all common cathode materials and also lithium titanate as the working electrode. However, some anode material such as lithium metal and lithiated graphite may react with the glass window forming greyish spots of elemental silicon on the glass surface. We therefore recommend using sapphire (Al2O3) windows with anode materials.

Sample test video: Electrochemical lithiation of a graphite electrode

In this experiment, the ECC-Opto-Std test cell has been used to visualize the color change of a graphite electrode during electrochemical lithiation. A 10 mm diameter free-standing graphite electrode was used as the working electrode (WE). The WE was sandwiched with a glass fiber separator and a lithium metal counter electrode. A holed copper foil was used as the WE current collector. The microscope “looked” through the 1 mm diameter hole in the copper foil onto the backside of the graphite electrode. One picture was taken every 5 minutes.

The time-lapse video starts at the fully lithiated state after the graphite electrode had been fully discharged overnight to 5 mV versus the lithium metal counter electrode. The next 2.5 cycles are shown, starting with the golden color of the fully lithiated graphite, and ending up with the silver-black color of almost pure graphite. Both charge and discharge were conducted at constant current with a rate of C/3, followed by constant voltage periods till the current had dropped to C/30.

Sample test video: Visualizing the potential gradient in a graphite electrode during electrochemical lithiation

In this video, we show how the ECC-Opto-Std test cell can be used to visualize a potential gradient inside graphite, just by using a standard graphite electrode with a continuous copper foil as the current collector (rather than a holed current collector).
