Because of the outstanding reliability of the built-in lithium metal reference electrode, the PAT-Cell is the ideal test cell for long-term 3-electrode experiments on Li-ion battery systems. The BioLogic VSP potentiostat, on the other hand, is a perfect match for controlling this type of experiment, as it is capable of monitoring the half cell voltages while controlling the full cell voltage.
In this report, we describe a typical cycling experiment of a lithium-ion battery comprised of an NCM cathode and a graphite anode (both with a capacity of approx. 2 mAh/cm2, purchased from CCI) in a conventional LiPF6 based electrolyte (1M in EC/DMC 1:1 with 2% VC, BASF).
