<p>Electrochemical impedance spectroscopy (EIS) of lithium insertion electrodes is a powerful technique to facilitate the further development of lithium-ion batteries (LIBs) because it provides useful information on electrochemical reactions. However, EIS methodology using a three-electrode cell is yet to be established owing to the difficulty in designing the reference electrode configuration. Therefore, a symmetric-cell method has been proposed to measure the EIS of a single electrode in a two-electrode cell, and it has been actively applied to EIS measurements in recent years. EIS measurements using symmetric cells have resulted in several new discoveries and deepened our understanding of the EIS behavior of lithium insertion electrodes. In this review, we outline the progress of EIS measurements using the symmetric-cell method for lithium insertion electrodes. First, we explain the principle, fabrication method, and EIS analysis of symmetric cells. Subsequently, an equivalent-circuit model representing lithium insertion electrodes is proposed based on the EIS measurement results. Furthermore, the factors affecting the various resistances comprising the equivalent circuit, such as charge transfer, contact, and ionic transport resistances, are discussed, including the dependence of the resistances on the electrode thickness, porosity, and measurement temperature on the resistances. Finally, applications of the EIS of a single electrode obtained using symmetric cells are described, including the prediction of the EIS of LIB and acquisition of the EIS of a single electrode from that of full cells.</p>

The power capability of lithium-ion batteries strongly depends on the reaction kinetics of the lithium insertion material used in the electrodes. Previously, chronoamperometry revealed that the lithium insertion reaction of MgMn2O4 differs between static and dynamic processes and that the dynamic process consists of a nucleation–growth process followed by diffusion. Herein, we present the overvoltage and temperature dependence of the reaction rate of MgMn2O4 through chronoamperometry results under different applied voltages and temperatures. The rate constant of each process is determined by fitting the measured current profile to a solid-state reaction model. The rate constant of the nucleation-growth process exhibits an Arrhenius relationship with temperature and a Tafel-like relationship with overvoltage, whereas that of diffusion exhibits an Arrhenius relationship with temperature and does not depend on overvoltage. These dependencies are different because nucleation–growth is a reaction process on the particle surface, whereas diffusion is a reaction process occurring inside the particle. Accordingly, the rate-determining step of lithium insertion under various operating conditions is discussed.

Since lithium-ion batteries are becoming increasingly popular, we aimed to increase the power density of lithium-ion batteries by improving the rate capability of lithium insertion electrodes by controlling the reaction mechanism of lithium insertion materials. LiNi0.5Mn1.3Ti0.2O4 (Ti-LNMO), in which a part of Mn4+ in LiNi0.5Mn1.5O4 (LNMO) was replaced by Ti4+, was synthesized and proceeded in a single-phase reaction over the entire region. This resulted in two types of LNMOs with the same spinel structures and solid-state redox reactions of Ni2+/Ni4+, each with different reaction mechanisms. According to rate-capability tests of these two types of LNMOs, the Ti-LNMO exhibited superior rate capability than the LNMO without Ti-substitution, which demonstrated that high-power capabilities could be achieved by controlling the reaction mechanism. Furthermore, the solid-state Li-ion diffusion coefficient in the LNMOs was determined from the rate-capability using the diluted electrode method, and that of Ti-LNMO was more than three times greater than that of the LNMO. These results reveal that the lithium insertion mechanism is important for the kinetics of lithium insertion reaction.

Spinel-structured ordered-LiNi0.5Mn1.5O4 (o-LNMO) has experienced a resurgence of interest inthecontext of reducing scarce elements such as cobalt from the lithium-ionbatteries. O-LNMO undergoes two two-phase reactions at slow rates.However, it is not known if such phenomenon also applies at fast rates.Herein, we investigate the rate-dependent phase transition behaviorof o-LNMO through in operando time-resolved X-raydiffraction. The results indicate that a narrow region of the solidsolution reaction exists for charge and discharge at both slow andfast rates. The overall phase transition is highly asymmetric at fastrates. During fast charge, it is a particle-by-particle mechanismresulting from an asynchronized reaction among the particles. Duringfast discharge, it is likely a core-shell mechanism involvingtransition from Li0+x Ni0.5Mn1.5O4 to Li1+x Ni0.5Mn1.5O4 in the outer layer of particles.The Li0.5Ni0.5Mn1.5O4 phaseis suppressed during fast discharge and appears only through Li redistributionupon relaxation.

With the rapid utilization of lithium-ion batteries (LIBs) in various applications, including automobiles, battery-lifetime extension has become an important issue. A major cause of capacity fading in batteries is the increase in the positive- and negative-electrode resistance, mainly due to the formation of highly resistive electrode films. Previous studies indicate that crosstalk reactions significantly influence the resistance-increase mechanism. Although previous publications confirm that the rate of positive-electrode resistance-increase is greatly affected by the negative-electrode potential, the quantitative relationship between the crosstalk reaction and cell-resistance increment remains unexplained. In this study, potentiostatic charge tests were performed on Li[Li1/3Ti5/3]O-4/LiNi1/2Mn3/2O4 cells by varying the charging voltage. Although the number of side reactions increased on increasing the charging voltage, the increase in cell resistance remained almost same; the Li[Li1/3Ti5/3]O-4 and LiNi1/2Mn3/2O4 electrode resistances increased significantly after potentiostatic charging. To explain the resistance-increase behavior of the cell, a phenomenological model incorporating the crosstalk reaction was proposed. Subsequently, this model was used to calculate the increase in cell resistance. The simulation results were consistent with the experimental results, indicating that the model could be used to quantitatively predict the increase in cell resistance.

To develop lithium insertion materials used in lithium-ion batteries in terms of reversible capacity, it is desirable for crystal structures that can reversibly accommodate more Li ions in the lattice. Conventionally, lithium insertion materials with the densest close-packed structures should have the highest volumetric capacity. However, in recent years, materials with non-closest-packed structures, such as TiNb2O7, have been paid much attention as high-capacity materials because they can accommodate an extremely large number of Li ions. In this study, we synthesized and characterized a series of binary W-Nb oxides for the high-volumetric-capacity negative electrode because it has many binary compounds having non-close-packed structures. All of the W-Nb oxides reversibly accommodate Li ions at the ratio of Li/M > 1, although the crystal structures are different between the W-rich phase with flower-type structures and the Nb-rich phase with block-type structures. The Nb-rich phases with block-type structures exhibit larger reversible capacity than the W-rich phases. The reaction mechanism of W3Nb14O44, which has the highest capacity among the binary oxides, was investigated by ex situ X-ray diffraction (XRD), and it was found that its volume change is small owing to a large free space in the crystal structure with non-close packing. Finally, to examine the feasibility of W3Nb14O44 as the high-capacity negative electrode, we fabricated a lithium-ion cell of W3Nb14O44 combined with a 5 V positive electrode material of Li[Ni1/2Mn3/2]O4 and performed a cycle test.

<p>Electrochemical impedance spectroscopy (EIS) is widely used for the analysis of various electrochemical devices, as it can quantitatively evaluate the main kinetic parameters related to electrochemical phenomena by analysis using equivalent circuits. This paper describes practical applications of EIS, along with EIS measurement and analysis methods for solid electrolytes, Li-ion batteries (LIBs), and electric double-layer capacitors (EDLCs). In all applications, it is necessary to properly measure the impedance data for an adequate equivalent circuit analysis. Therefore, after presenting the backgrounds of EIS applications in the Section 1 (Introduction), the experimental cautions in the measurements are discussed in detail in Sections 2–4. Section 2 (“EIS for Solid Electrolytes”) presents practical examples of measurements for accurate data, as the EIS analysis of solid electrolytes requires impedance data in the high-frequency range above 1 MHz. Section 3 (“EIS for Lithium-Ion Batteries”) describes a method of separating the internal resistance into the resistances of the positive and negative electrodes and electrolyte resistance, as the output power capabilities of LIBs are frequently evaluated based on an internal resistance. In particular, a symmetrical cell technique enabling measurements of the impedance data only for the positive or negative electrode is demonstrated. As described in Section 4 (“EIS for Electric Double-Layer Capacitors”), the excessive and unwanted impedances arising from instruments and cells must be suppressed as much as possible for appropriately measuring the correct EIS of EDLCs, because the resistance of EDLCs is very small. Therefore, the experimental setup that should be considered in EIS measurements for EDLCs leading to disturbed impedance data is discussed, along with the effects of this scenario on the impedance data. Finally, we summarize our conclusions in Section 5 (Summary).</p>

<p>Electrochemical impedance spectroscopy (EIS) enables the examination of the electrochemical nature of electrodes and electrochemical cells by applying an alternating voltage (or current) and measuring the resulting current (or voltage). The resistance and capacitance components of the electrode can be evaluated by applying an AC voltage and changing the frequency. In particular, analysis using the equivalent circuit can determine important parameters related to the electrochemical reaction of the electrode, such as the charge transfer resistance, electric double-layer capacitance, and Warburg impedance. Moreover, the internal resistance of the cell can be divided into resistances caused by the positive electrode, negative electrode, and electrolyte. Because of these advantages, EIS is a powerful technique used for basic research, such as in identifying the rate-determining step of an electrochemical reaction, and also for applied research, such as characterizing electrochemical devices (e.g., batteries and capacitors). In this paper, the concept of impedance, which represents the relationship between the AC voltage and current, is first explained; then, the AC characteristics of various circuit elements used in equivalent circuits, which are essential for understanding EIS, are described. Finally, treatments of more complex circuits based on transmission-line models (TLMs), which are used to represent equivalent circuits of porous electrodes, are presented. Analyses based on TLMs are the foundation for understanding electrodes for practical applications because porous electrodes are usually used in electrochemical devices.</p>

<p>To establish the kinetics of the lithium insertion materials used as the electrodes in lithium-ion batteries, it is important to clarify the diffusion phenomena of lithium ions in the solid phase. Since there are two variations of the rate-determining step of a lithium insertion electrode (Li-ion diffusion in solid particles and that in the electrolyte solution), these have to be differentiated in any investigation of the diffusion phenomena of Li ions in a solid. In this study, we calculated the rate capability of diluted electrodes using a charge–discharge simulation program and proved that the transport of Li ions in the solid phase is the rate-determining step for a diluted electrode with an extremely low active material content. In addition, the solid-state Li-ion diffusion coefficient can be calculated by analyzing the results of the rate capability tests. These results reveal that the diluted electrode method is very useful for elucidating the solid-state Li ion diffusion phenomena of lithium insertion materials. As such, the rate capability tests provide a new means of analyzing the solid-state diffusion coefficient.</p>

A 2.5-V battery consisting of lithium titanium oxide (LTO) and lithium aluminum manganese oxide (LAMO) having spinel-framework structures was examined from 1 to 3 V at 55 °C. After several trials on capacity retention at high temperatures, we have succeeded to show that the rechargeable capacity is retained at greater than 80% even after 3600 cycles at 55 °C by applying cellulose nonwoven cloth as a separator, satisfying requirement for 12-V automobile applications.

Lithium nickel manganese oxides having 20% nickel excess and deficient with respect to the stoichiometric Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub> having a space group symmetry of <i>P</i>4<sub>3</sub>32 were prepared and examined in nonaqueous lithium cells. Rechargeable capacity observed for the 20% nickel excess sample in voltage above 4.5 V is larger than that for the 20% nickel deficient sample. The effect of deviation from Ni/Mn stoichiometry from the ideal composition of Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub> upon the rechargeable capacity at 4.7 V is described in terms of the solid solution, phase separation, and superstructural Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub>. From the results, the composition preferable to the five-volt lithium insertion material of Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub> is discussed. The cycling stability of Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub> in the cell with the Li[Li<sub>1/3</sub>Ti<sub>5/3</sub>]O<sub>4</sub>-negative electrode is also examined in voltages ranging from 1.5 to 3.6 V at 25°C for 250 cycles and shown that the capacity fading of the cell is negligibly small below 4% even after 250 cycles.

<p>Recent progresses on insertion materials for lithium-ion batteries are described. Understanding of solid state chemistry and electrochemistry of LiCoO<sub>2</sub>, LiNiO<sub>2</sub>, LiMn<sub>2</sub>O<sub>4</sub>, LiC<sub>6</sub>, and so forth was a first step and their modification in terms of solid solution among the same crystal family was a second step. However, materials innovation is restricted because of the limitation of chemical species unless new concept is introduced. Old, but quite new concept is so-called "superlattice" model with which one can design hypothetical lithium insertion materials, calculate electronic and crystal structures by using computational methods, and develop effectively in an empirical basis. To demonstrate the new concept, systematic researches on materials based on superlattice models in a phase triangle of LiCoO<sub>2</sub>-LiNiO<sub>2</sub>-LiMnO<sub>2</sub> leading to novel binary or ternary oxides of lithium with transition metal elements, <i>i.e.</i>, LiNi<sub>1/2</sub>Mn<sub>1/2</sub>O<sub>2</sub>, LiCo<sub>1/3</sub>Ni<sub>1/3</sub>Mm<sub>1/3</sub>O<sub>2</sub>, and Li[Ni<sub>1/2</sub>Mn<sub>3/2</sub>]O<sub>4</sub>, are highlighted.</p>
