<p>Three different types of Co₃O₄-based anode materials with different binders: polyvinylidene fluoride (PVDF), polyacrylic acid with carboxymethyl cellulose (PAA/CMC) and poly(3,4-ethylenedioxythiophene): polystyrene sulfonate with CMC (PEDOT: PSS/CMC) were investigated. It was demonstrated previously that the use of the conductive binder PEDOT: PSS/CMC significantly increased the electrochemical performance of the anode materials even at a current density of 1&#xa0;C (890 mA∙g⁻¹). The cycling stability was also much higher in comparison with that of the two other electrodes. These effects can be explained by the presence of the conducting polymer PEDOT: PSS as a binder component. To confirm this, impedance spectra of all three electrodes at different states of charge were obtained. It was observed that Co₃O₄-based anode with the PEDOT: PSS/CMC binder has the lowest charge transfer resistance (<i>R</i>_ct), which indicates improving the kinetics of the electrochemical reaction. Furthermore, the presence of a linear part in the impedance spectra allowed for the qualitative evaluation of diffusion limitations. The values of the Warburg constants, as well as the associated diffusion coefficients of lithium ions, are the smallest for the Co₃O₄/PEDOT: PSS/CMC electrode compared to the other two electrode materials, which means improving the ionic conductivity of the electrode composition. Thus, it can be concluded that the improved functional properties of electrodes based on Co₃O₄ with PEDOT: PSS are associated with faster electronic and ionic transport of charge carriers.</p>
