Title: On the electroanalytical characterization of Li{sub x}CoO{sub 2}, Li{sub x}NiO{sub 2} and LiMn{sub 2}O{sub 4} (spinel) electrodes in repeated lithium intercalation-deintercalation processes

Abstract

This paper reports on electroanalytical studies of the intercalation-deintercalation of lithium into lithiated transition metal oxides which are used as cathodes for Li ion batteries. These include Li{sub x}CoO{sub 2} Li{sub x}NiO{sub 2} and Li{sub x}Mn{sub 2}O{sub 4} spinel. The basic electroanalytical response of these systems in LiAsF{sub 6} 1M/EC-DMC solutions was obtained from the simultaneous use of slow and fast scan cyclic voltammetry (SSCV), potentiostatic intermittent titration (PITT) (from which D vs. E was calculated), and impedance spectroscopy (EIS). Surface sensitive FTIR spectroscopy and XRD were also used for surface and 3D characterization, respectively. A large and important denominator was found in the electrochemical behavior of lithium intercalation-deintercalation into these transition metal oxides and graphite. The use of the electroanalytical response of these systems as a tool for the study of stabilization and failure mechanisms of these materials as cathodes in rechargeable Li batteries is demonstrated and discussed.
