Page 8: Cell Assembly
5 Cell Assembly The test cell can either be operated in 2-electrode or 3-electrode (reference) configuration. In the following, the cell assembly is described for operation with a lithium metal reference electrode. Generally, all assembly steps are to be carried out in inert glove box atmosphere, and all components used are to be dried upfront in a vacuum oven at 80°C for at least 12 hours. - Page 9 vii) Put the glass fibre separator into the sleeve and dispense a defined amount of electrolyte onto it. The optimum amount of electrolyte depends on the electrodes and separator used, and has to be carefully determined in pre- tests. 0.5 cm are a reasonable amount for 1.5 mm thick glass fiber separator.

Page 13: Sample Valve With Septum Port
8 Sample Valve with Septum Port The gas sample valve serves to draw gas samples from the head space of the ECC- Press-Air test cell. In the closed state, the valve spindle is seated on the PTFE ferrule and is thus preventing any bleeding from inside the cell through the septum. In order to draw a gas sample, i) pierce the septum with the sample syringe, ii) open the valve by turning the valve handle counter-clockwise by 90 degrees, iii) charge the syringe, iv) close the valve by turning the valve handle clockwise till finger tight, and remove... -

Page 15: Recording The Pressure Signal With An External Potentiostat
Many of today’s battery testers and potentiostats provide additional analog inputs that may be used to record sensor signal along with cell current and potential. In the following, the combination of the ECC-Press-Air-DL with a Biologic potentiostat (MPG-2, SP, VSP and VMP series) is described as an example. The Biologic potentiostats feature two analog inputs that are used here to record both pressure and temperature. -
Page 16: Disassembly And Cleaning
11 Disassembly and Cleaning Right after use, disassemble the cell in the reverse order of assembly. Note that the reference pin MUST be detached before the REF sleeve can be removed. All chemicals used have to be disposed properly. All wetted parts are to be cleaned with water and/or other appropriate solvents. -
