Automotive cells are tested at different temperatures to determine their electrical properties and durability. Additional measurement techniques, such as EIS, are also applied.
To create a battery anode, battery paste is first applied to copper foil and then dried.
Left: being used to measure whole cells. Right: being used to characterise electrode structures.
During the cell positioning process, priority is given to ensuring flexibility, reverse polarity protection, automated test starts and short set-up times so as to avoid impacting other cell tests being performed.
Initial base compositions and samples are tested and characterised in terms of capacity and performance, using either half- or full-cells and, optionally, reference electrodes.
Cells are tested beyond their operating limits in specially constructed safety test chambers to determine their safety characteristics. The standardised test chambers provide the flexibility to integrate a variety of equipment, structures and devices. An innovative, self-regenerating filter system reliably cleans off the build up of corrosive gases.
