Three-dimensional electrochemical Li-ion battery modelling featuring a focused ion-beam/scanning electron microscopy based three-phase reconstruction of a LiCoO2 cathode

Additionally, we study lithium/salt concentration in the electrolyte, revealing gradients between 0.9 and 1.5 kmol m−3 depending on the distance to the separator. This is significant because the lithium/salt concentration directly affects the ion transport properties of the electrolyte.
