2 Experimental Setup

The experimental testbed used to perform the ageing tests is derived from that used in [18] (see Fig. 1). It consists of a source meter unit (SMU) Keithley 2420 controlled by a LabVIEW application running on a host PC. The SMU is used to charge and discharge the Li-ion cells and to measure the voltage and the current during the tests. The temperature of the cells under test is kept constant by using the Binder MK53 thermal chamber. The cells employed in this test campaign are the LGDBHE21865 cells by LG Chem. Their nominal capacity is 2.5A h, which is defined as the charge extracted during a constant current (CC) discharge at 0.2C (i.e., 0.5A) ended at 2.5V, after a CC charge at 0.5C (i.e., 1.25A) with a cut-off voltage of 4.2V followed by a constant voltage (CV) charge at 4.2V with a cut-off current of 50mA.
