However, various kinds of anomalous behavior of lithium transport have been reported in many current transients (CTs) and voltammetric curves obtained with a number of transition metal oxides and carbonaceous materials. In spite of the fact that many researchers... 

This Chapter discusses lithium transport through transition metal oxides and carbonaceous material (graphite) during CT experiments. The structure of this review is as follows in Section II, the conventional and modified diffusion control models for explaining the CTs are briefly summarized. Typical experimental CTs from transition metal oxides and carbonaceous material (graphite) are presented and then several anomalous behaviors in these curves are pointed out in Section... 

Pyun et al. started " their exploration of the anomalous current response with the CTs obtained from Lii.sCoOj which is the cathode material of almost all commercially available rechargeable lithium batteries today. They reported that the CTs obtained from U1.SC0O2 composite and thin fitm " electrodes hardly exhibit a typical trend of diffusion controlled lithium transport, i. e. Cottrell behavior. Furthermore, they have found that the current-potential relation obeys Ohm s law during the CT experiments. They thus suggested that lithium transport at the interface of the electrode and the electrolyte is mainly limited by the internal cell resistance, and not by lithium diffusion in the bulk electrode. This concept is called the cell-impedance controlled lithium transport.
