Analysis of ferrate (VI) compounds and super-iron Fe(VI) battery cathodes: FTIR ICP, titrimetric, XRD, UV/VIS, and electrochemical characterization

摘要

Chemical and electrochemical techniques are presented for the analysis of Fe(VI) compounds used in super-iron electrochemical storage cells. Fe(VI) analytical methodologies summarized are FTIR, ICP, titrimetric, UV/VIS Fe(VI), potentiometric, galvanostatic, cyclic voltammetry, and constant load, current or power electrochemical discharges probes. The investigated FTIR methodology becomes quantitative with introduction of an internal standard such as added barium sulfate.
