Assembly of the ECC-Opto-Gas optical test cell

Watch this video to learn how to assemble the ECC-Opto-Gas. This test cell specializes in the optical characterization of gas diffusion electrodes in metal-air batteries.
Dr. Matthias Hahn will guide you through all necessary steps, including pre-assembly and leak testing, cell filling and final assembly in the glove box environment.

Electrochemical dilatometer

Assembly of the ECD-3-nano electrochemical dilatometer

In this video, you will learn how to assemble an ECD-3 electrochemical dilatometer inside the glove box, how to connect it and finally how to adjust the sensor for testing.

How to assemble the PEEK insulation sleeves

In this video we will show you how to assemble the PEEK insulation sleeves in a few steps. In contrary to the preassembled single-use PAT-Core variants made of PP, the PEEK components need to be assembled before each use but have the advantage of reusability.

ECC-Opto-Std

ECC-Opto-Std Mode 3: Graphite electrode sandwiched with an LFP counter electrode

Using our ECC-Opto-Std test cell, we have placed a strip of a graphite electrode beside a piece of lithium foil having the shape of a semicircle. A glass fiber separator is pressed against this side-by-side assembly from below, so as to fill up the gap between the two electrodes. From below, a lithium iron phosphate (LFP) electrode is pressed against the separator serving as the counter electrode. The microscope “looks” through the sapphire window onto the graphite electrode with the active layer facing up, and the current-less lithium metal foil beside. For the electrochemical experiment, the graphite strip is connected to the working electrode of the potentiostat, the LFP semicircle to the counter electrode, and the lithium metal foil to the reference electrode. The video shows how the color gradient evolves along the width of the graphite electrode during lithiation/ delithiation.

ECC-Opto-Std Mode 2: Visualizing lithium dendrite growth in a graphite vs lithium metal cell

Using our ECC-Opto-Std test cell, we have placed a strip of graphite next to a lithium metal electrode (having the shape of a semicircle) on top of a glass fiber separator soaked with electrolyte. A sapphire window is placed on top of the assembly. By means of the applied mechanical pressure, the soft glass fiber separator deliberately fills up the gap between the graphite strip and the lithium metal electrode. We call this a side-by-side arrangement, because the two electrodes are placed side-by-side rather than being sandwiched as in a conventional set-up.

ECC-Opto-Std Mode 1: Graphite electrode strip sandwiched with LFP Counter electrode

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).

ECC-Opto-Std Standard sandwich mode: Free-standing graphite electrode on holed current collector

In this experiment, the ECC-Opto-Std test cell has been used to visualize the color change of a graphite electrode during electrochemical lithiation.

ECC-Opto-Std Assembly Mode 3 (3-electrode side-by-side setup)

In this video, we show how to build the ECC-Opto-Std test cell in the alternative assembly mode #3.
Again, a 1 mm wide electrode strip, cut from a conventional graphite electrode with copper foil current collector, is being used as the working electrode,and again this electrode strip is placed beside a piece of lithium metal foil.
However, this time the lithium metal is connected only to the reference electrode of the potentiostat, while a lithium iron phosphate electrode, placed below the graphite strip, is serving as the counter electrode.

ECC-Opto-Std Assembly Mode 2 (2-electrode side-by-side setup)

In this video, we show how to build the ECC-Opto-Std test cell in the alternative assembly mode #2.
Again, a 1 mm wide electrode strip, cut from a conventional graphite electrode with copper foil current collector, is being used as the working electrode.
This time, the electrode strip is placed beside a lithium metal foil connected to both the counter and the reference electrode of the potentiostat.
With a microscope “looking” through the window, we can observe the color change of the graphite during charge and discharge
and, at the same time, the growth of dendrites at the lithium metal counter electrode.

ECC-Opto-Std Assembly Mode 1 (2-electrode sandwich setup)

In this video, we show how to build the ECC-Opto-Std test cell in the alternative assembly mode #1.
A 1 mm wide electrode strip, cut from a conventional graphite electrode with copper foil current collector, is being used as the working electrode. This electrode strip is sandwiched with a lithium iron phosphate electrode connected to both the counter and the reference electrode of the potentiostat.
Importantly, the graphite layer is pointing towards the window on top, so that the current can only enter from the two edges of the graphite strip. This face-up geometry results in a gradient of the local electrode potential along the width of the electrode strip, rather than into the depth of the graphite layer.

Assembly of the ECC-Opto-Std (Standard sandwich setup)

This video shows the general assembly of the test cell ECC-Opto-Std; a test cell for optical and X-ray characterization in the reflective mode.
