Battery Sample Holder (Transmission):
The procedure for preparing the coin cells for the
battery sample holder (transmission) is described
below:
1. Place the battery sample holder together with all
necessary components for the assembly of the
battery in a glove box.
2. Remove the four screws on the lid (1) of the bat-
tery sample holder.
3. Remove the foils (2+3) and cathode (4) of the
battery sample holder.
4. Place the assembled coin cell (5) on the anode
(6).
5. Place the cathode on the coin cell.
6. Place first the Kapton foil (3) on the cathode, fol-
lowed by the graphite foil (2). (The use of the
graphite foil is optional. See also chapter 8.3.4).
7. Mount the lid (1) of the battery sample holder
again by the use of the 4 Torx screws.
An exploded-view drawing showing all the compo-
nents (including the assembled coin cell) is shown
below.

11 Basis of sample holder
After the complete assembly of the battery sample
holder, the sample holder can be extracted from the
glove box and mounted on the heater of TTK 600
(see also chapter 8.4.6
for further details).
8.3 Guideline for the correct choice of
conditions and foil materials
The following guideline can be used for the optimal
choice of the foil material for the transmission sam-
ple holder.
8.3.1 Temperature Range
Whenever the Kapton foil is used, the max. tem-
perature of the experiment must not exceed 230 °C.
Higher temperatures would result in a destruction of
the foil material.
Both, nickel and graphite, do not limit the tempera-
ture range of the experiment.
For operation in air the max. temperature is limited
to 450 °C.
8.3.2 Temperature accuracy and influence of
convection heater
The thermal conductivity of the offered foils is as fol-
lows:
Kapton ~ 0.2 W/mK
Nickel ~ 80 W/mK
Graphite ~ 140 W/mK
The better the thermal conductivity of the foil, the
lower is the temperature difference between dis-
played temperature on CCU 100 and real tempera-
ture on the surface of the sample. As a
consequence of this, for nickel and graphite, the ad-
ditional convection heater is obsolete. Due to the
high thermal conductivity, these foils transport the
heat very efficiently and do not need the additional
heat transfer mechanism of convection.
Kapton has a quite poor thermal conductivity. In this
case the additional convection heating improves the
temperature accuracy of the instrument. The opti-
mal gas flow for the Kapton foil is 0.5 L/min.
Therefore the temperature accuracy and the condi-
tions used for the different foils can be summarized
as follows:
Graphite (0 L/min) > Nickel (0 L/min) > Kapton
(0.5 L/min)

Risk of damage.
Use of the Kapton foil limits the max. tempera-
ture to 230 °C
