Electrochemical impedance spectroscopy (EIS) enables the examination of electrochemical nature electrodes and cells by applying an alternating voltage (or current) measuring resulting current voltage). The resistance capacitance components electrode can be evaluated AC changing frequency. In particular, analysis using equivalent circuit determine important parameters related to reaction electro...

This paper deals with the problem of estimating the state of charge (SOC) of lithium-ion batteries. Based on the analysis of the impedance spectra obtained by electrochemical impedance spectroscopy (EIS), a simplified battery impedance model is derived with the constant phase element (CPE). To interpret the impedance model, a fractional order calculus (FOC) method is introduced to model the CPE...

This paper deals with the development of an electrochemical sensor base on Trypan Blue (TB) towards the determination of Dopamine (DA). An electrochemical sensor was fabricated by the electropolymerization of TB onto the Carbon paste electrode (CPE) using cyclic voltammetry (CV) technique. The polymerized TB modified CPE (Poly(TB)MCPE) was characterized using Electrochemical impedance spectrosc...

In this work, electrochemical methods such as Tafel polarization and electrochemical impedance spectroscopy (EIS) were used to study the inhibition efficiency of Nettle leaves hydroalcoholic extract as a green corrosion inhibitor of API 5L carbon steel in 0.5 M H2SO4 solution. The results showed that the inhibition efficiency was increased with increasing the concentration of the extract and th...

the supercapacitive behavior of polyaniline/mno2-carbon black (pani/mno2-cb), mno2-cb nanocompositesand cb was studied. mno2-cb made by the in situ direct coating method to deposit mno2 onto cb; then pani coating was coated on it. morphology of the nanocomposite was studied by x-ray diffraction (xrd), fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the el...
