1Product Description
The ECC-Opto-10 test cell is designed for operando characterization of electrodes using
optical methods such as light microscopy or Raman spectroscopy in reflection mode.
The ECC-Opto-10 is connected to the battery tester via 2 mm cell cable with banana plugs. It
can be used with the PAT-Tester-x-8 as well as potentiostats and battery testers from third-
party manufacturers.
Features
2- and 3-electrode cell with optical window for aprotic and aqueous electrochemistry.
High cycling stability due to glass-to-metal seals
Suited for light microscopy and Raman spectroscopy
Fits on standard microscope sample stages (76 × 26 mm (DIN ISO 8037-1))

3 Intended use
The ECC-Opto-10 test cell is an electrochemical measuring instrument designed for use in a
laboratory environment. It may only be used by trained personnel and only as described in
this manual.
4Safety Precautions
Use proper safety precautions when using hazardous electrode materials and electrolytes.
Wear protective glasses and gloves to protect you against electrolyte that may accidentally
spill out during filling and disassembly. Upon cell disassembly, dispose all materials properly.
Metallic lithium and some insertion compounds may decompose heavily in contact with water
and other solvents, and can cause fire.

5 Assembly
Generally, all assembly steps are to be carried out in inert glove box atmosphere. All
components used are to be dried upfront in a vacuum oven at 80°C for at least 12 hours. Once
fully assembled, the cell is hermetically sealed so that it may be operated in ambient
atmosphere.
The test cell can be used in several different configurations, which mainly differ in the type
and size of the working electrode used, the charging geometry (the position of working and
counter electrode relative to each other), and the connection to the potentiostat (2- or 3-
electrode connection). In the following, the cell assembly is described for the side-by-side
arrangement of electrodes.
Assembly instructions:
1.Turn the lid upside down. Insert the
foil sealing into the lid.
2. Insert the window.

3. Insert the window thrust ring.
4 Attach the window flange and screw in the
screws using the torque screwdriver 0.2 Nm.
5. Insert the lower piston into the inner
sleeve.
6. Use the loading tweezer to push the
piston into the sleeve.

7. Place the assembly into the cell base.
8. Insert the sample holder into the loading
tweezers.
9. Squeeze the tweezer together to lift the
sample holder bracket. Then attach the first
electrode strip to the sample holder.
10. Turn the sample holder around and
place the second electrode strip.

11. Put the electrode R, lithium metal in this
case, on top of the piston.
12. Put the separator on top. The separator
must not be more than 10 mm in diameter.
A smaller separator may be useful to
prevent the sample holder from coming into
contact with the electrolyte.
13. Use the loading tweezer again to push
the cell stack further down.
14. Attach the sample holder. Make sure the
markings 1 and 2 on the sample holder and
cell base are aligned.

15. Insert the second foil seal.
16. Drop the electrolyte onto the separator /
electrodes. Use only the amount of electrolyte
necessary to impregnate the porous material.
Avoid an excess of electrolyte. Typically, less
than 50 µl of electrolye is suitable. Note that
electrolyte will be squeezed out of the
separator when the cell lid is attached.
17. Put on the cell lid. Make sure that the
flat side of the cell base and the straight line
on the lid are parallel.
18. Finally, screw the cover on with the 2.5
mm hexagon screwdriver.

6 Connecting the test cell
Connect your potentiostat to the 2 mm
sockets of the cell. Note that sockets 1 and
1S are short-circuited inside the cell housing,
as are sockets 2 and 2S.
19. The ECC-Opto-10 is now ready for
testing.

7Disassembly and Cleaning
Right after use, disassemble the cell in the reverse order of assembly. All chemicals used have
to be disposed properly. All wetted parts are to be cleaned with water and/or other
appropriate solvents. All parts are to be dried immediately after cleaning at 80°C.
NOTE: Leaving cell parts in contact with ambient atmosphere while still being wetted with
electrolyte may result in severe corrosion.
8Unpacking
