Assembly:
i)
By means of the optionally available
, press a small piece of
lithium metal into port C so that the Li metal just appears at the upper narrow
end of the feed-through hole. Attach the spring-loaded reference pin to the
port. Skip this initial step if working without reference electrode.
ii)
Push the counter electrode piston into the cell body to the uppermost position.
iii)
Pull the piston slightly back, and insert the Li counter electrode (max. 10 mm
in diameter, max. 1 mm thick)
iv)
Put the provided glass fiber separator on top.
v)
Place the WE material onto the center of the separator. The WE material can
either be a self-supported electrode film, a single grain/ crystal, or a small
amount of powder.
vi)
Cover the WE material with one of the provided (holed) current collectors. Use
Al foil for excursions to potentials >1.5 V vs. Li/Li
+
, Cu foil for excursions to
potentials between 0 and 3 V vs. Li/Li
+
.
vii)
Insert the upper O-ring seal into the cell body, and place the optical window on
top. Make sure that the window is in the center position.
viii)
Attach the cell lid and fasten the three hex socket screws.
ix)
Attach the WE contact pin to port A.
x)
Attach the touch screw from below and raise it to the uppermost position; then
turn the touch screw back (counter-clockwise) by about 30°.
xi)
Fill the cell with electrolyte according to the following procedure.
1. Connect the provided transfer (fill) line to port B.
2. Charge a 5 mL syringe with ca. 1 mL of electrolyte.
NOTE
: We recommend
one-time use PP plastic syringes with low friction polysiloxane pistons.
3. Connect the syringe to the Luer adapter of the transfer line.
4. Pull the syringe piston back to evacuate the cell. Hold the piston a few
seconds in the strained position.
5. Release the piston so that the electrolyte is being drawn deliberately into
the cell.
NOTE
: Never pressurize the cell during the filling procedure.
6. Repeat the two previous steps to complete filling.
7. Remove the transfer line and close port B with the provided plug.
Optionally port B may be plugged with the second WE contact pin
assembly.
xii)
Insert the cell into the stand.
xiii)
Connect the cell to your potentiostat/ galvanostat or battery tester via the
2 mm banana sockets.
