Application of FeOCl derivatives for a secondary lithium battery. III. Electrochemical reaction and physical state of reaction product of FeOCl with aniline in water

Article abstract of DOI:10.1149/1.2044262

The reaction product of FeOCl with aniline in water was subjected to various analyses before and after its discharge and charge to determine its physical state and electrochemical reactions. From these analyses, it can be seen that there are two possible states for the reaction product before the discharge; one is a mixture of γ-FeOOH and aniline derivatives (polymer or oligomer of aniline), and another is a mixture of γ-FeOOH and FeOOH incorporating aniline derivatives. Atomic absorption analyses during discharge and charge cycles show that the steady-state discharge and charge processes are associated with a reversible change in lithium content in the solid matrix which change corresponds to the amount of electric charge passed. The Fourier transform infrared spectra indicate that the redox reaction of aniline derivatives (doping and undoping with anions) occurs during discharge and charge cycles. These results show that aniline derivatives exist in a different state from that of a simple mixture of the states of aniline derivatives and FeOOH.
