“…The EIS data for various electrodes used in LIBs are listed in Table 2. for all electrodes are increased after 10th discharging because of continuous SEI formation on the surface of the particles [34,35]. The ct values of the LIBs with the fresh NCA, NCA-Mn, and NCA-Ti electrodes are 191.9, 159.2, and 124.2 Ω, respectively, while the corresponding values after 10 cycles are 357.9, 300.8, and 238.4 Ω.…”

“…Nyquist plots of the fresh NCA, NCA-Mn, and NCATi electrodes and the electrodes after the 10th cycle are shown in Figure 8. Experimental results shown in solid lines are fitted by the equivalent circuit in the inset of Figure 8 Journal of Nanomaterials [32][33][34][35][36]. The Nyquist plots exhibit identical electrochemical behaviors with semicircles in the high-frequency region and a straight sloping line at low frequencies.…”

NCA (LiNi 0.85 Co 0.10 Al 0.05−x M x O 2 , M=Mn or Ti, < 0.01) cathode materials are prepared by a hydrothermal reaction at 170 ∘ C and doped with Mn and Ti to improve their electrochemical properties. The crystalline phases and morphologies of various NCA cathode materials are characterized by XRD, FE-SEM, and particle size distribution analysis. The CV, EIS, and galvanostatic charge/discharge test are employed to determine the electrochemical properties of the cathode materials. Mn and Ti doping resulted in cell volume expansion. This larger volume also improved the electrochemical properties of the cathode materials because Mn 4+and Ti 4+ were introduced into the octahedral lattice space occupied by the Li-ions to expand the Li layer spacing and, thereby, improved the lithium diffusion kinetics. As a result, the NCA-Ti electrode exhibited superior performance with a high discharge capacity of 179.6 mAh g −1 after the first cycle, almost 23 mAh g −1 higher than that obtained with the undoped NCA electrode, and 166.7 mAh g −1 after 30 cycles. A good coulombic efficiency of 88.6% for the NCA-Ti electrode is observed based on calculations in the first charge and discharge capacities. In addition, the NCA-Ti cathode material exhibited the best cycling stability of 93% up to 30 cycles.

“…For instance see Figure 6 of Reference 15, as well as many others. 2,3,16 So far, many formulas were shown, but in order to demonstrate that they work in a real example, Figure 9 uses the code to convert from a Voight configuration (with a series capacitor) to a ladder configuration (with a capacitor embedded in the inner part of the ladder). Figure 9c shows the two circuits considered.…”

Despite the accuracy and non-intrusive nature of Electrochemical Impedance Spectroscopy, the impedance spectra of commercial Lithium-ion cells are notoriously hard to interpret. Consequently, the literature is filled with various equivalent circuit models, which differ greatly in their physical significance, but which produce very similar impedance spectra. In this paper, explicit formulas are given to convert between various equivalent circuits made of resistors and capacitors of the sort discussed in the literature. Furthermore, all these formulas have been implemented in a Python program, in the hope that studies done assuming one circuit might be compared to studies done with a different circuit, for instance. This paper considers cases where two different circuits can produce two impedance spectra which are identical. For instance, explicit conversions are given between Ladder circuits, Voight circuits, and Maxwell circuits for various time constants. This gives a conceptual foundation to explore the more difficult case of circuits producing impedance spectra which are similar to each other (e.g. within 5%).

“…EIS often becomes a technique of choice to study the electrified interface and hence has been used in lithium ion batteries. Briefly, the EIS literature on lithium 6 ion batteries may be represented by typical papers such as those by Zhuang et al [14] and Chagnes et al [15]. Chang et al [16] have described and discussed the development of new EIS methods to reduce measurement time.…”

A study of 40 Ah lithium ion batteries at zero percent state of charge as a function of temperature

A theoretical equivalent circuit model of two 40Ah commercial batteries supplied by Saft was formulated to interpret electrochemical impedance spectra as a function of temperature at zero state-of-charge. The batteries were chosen to represent viable and non-viable products from the Saft production line. This paper is the first contribution from a project in Newcastle to develop a rapid, non-destructive analytical method for quality control on the battery production line. Using the model, it proved straightforward to discriminate between viable and non-viable batteries based on the temperature dependence of the electrochemical reaction kinetics at the electrodes, the average diffusion coefficients and the charge transfer resistances. Furthermore, as well as marked differences, for example, between the time constants, activation energies, polarisation resistances of the viable and non-viable batteries, the individual contributions of the anodes and cathodes in the batteries were de-convoluted and interpreted through the model framework.5
