5 Assembly and Connection
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 either 2-electrode or 3-electrode (reference) configuration.
In the following, the cell assembly is described when using lithium metal reference
electrode.
Assembly:
1.
By means of the optionally available
, press a small piece of lithium
metal into port REF so that the Lithium metal just appears at the upper narrow
end of the feed-through hole. Skip this initial step if working without reference
electrode.
2.
Push the counter electrode piston into the cell body to the uppermost position.
3.
Pull the piston slightly back, and insert the Lithium counter electrode (max. 10
mm in diameter, max. 1 mm thick)
4.
Put the provided glass fiber separator on top.
5.
Place the working electrode on top of the separator, with the active layer pointing
UPWARDS. The working electrode may be fabricated by pressing together a self -
standing electrode (up to 10 mm in diameter) and the provided 16 mm current
collector mesh.Insert the upper O-Ring seal (16 x 1.8 mm) into the cell body, and
place the optical window on top. Make sure that the window is in the center
position.
6.
Attach the lid and fasten the three socket screws.
7.
Attach the WE contact pin to port A.
8.
Attach the reference pin to the reference port. Plug the reference port if working
without reference electrode.
9.
Attach the touch screw from below and raise it to the uppermost position; then
turn the touch screw back (counter clockwise) by about 30°.
10.
Fill the cell with electrolyte according to the following procedure.
Connect the provided filling tube to port B.
Charge a 5 ml syringe with ca. 0.5 ml of electrolyte. NOTE: We recommend
single-use PP plastic syringes with low friction silicone pistons.
Connect the syringe to the Luer adapter of the filling tube.
