Li-ion batteries (LIBs) are dominating the marked for advanced energy storage technology, but has not yet reached its full potential with regards to energy density at cell and pack level. One strategy for increasing the energy density at cell and pack level is to increase the thickness of the active electrode, and thereby reducing the relative amount of inactive components. However, this has proven difficult, as increased electrode thickness leads to several challenges related to limited kinetics, transport and delamination, which lead to capacity degradation. Obtaining fundamental understanding of how electrode thickness affects the degradation processes in active materials is crucial for the further development of LIBs [1]. The effects of electrode thickness is likely highly dependent on the type of active material and the applied cycling rates. Therefore, we aim to study graphite (anode) and LFP (cathode) of 2 different thicknesses, cycled at 3 different rates with operando XRD.
