“…This inherent restriction prevents a high cathode utilization, and also geometrical properties and morphological changes of the microstructure interact with internal and external interfaces, which significantly affect the capacity retention at higher current rates. Nakamura et al [231] further improved the coating technology of electrodes and electrolytes and reported uniformly coating LPS on an NMC111 cathode using the dry-coating technique. This technique is advantageous owing to Neumann et al [230] further studied the LPS electrolyte/NMC622 microstructure and interface topology using X-ray tomography and 3D microstructure-resolved simulations and combined impedance technique and electrochemical studies that revealed the low electronic conductivity of in the fully lithiated NMC622 material (σ = 1.42 × 10 −4 S cm −1 for Li = 0.4 down to 1.6 × 10 −6 S cm −1 for Li = 1).…”

Energy storage materials are finding increasing applications in our daily lives, for devices such as mobile phones and electric vehicles. Current commercial batteries use flammable liquid electrolytes, which are unsafe, toxic, and environmentally unfriendly with low chemical stability. Recently, solid electrolytes have been extensively studied as alternative electrolytes to address these shortcomings. Herein, we report the early history, synthesis and characterization, mechanical properties, and Li+ ion transport mechanisms of inorganic sulfide and oxide electrolytes. Furthermore, we highlight the importance of the fabrication technology and experimental conditions, such as the effects of pressure and operating parameters, on the electrochemical performance of all-solid-state Li batteries. In particular, we emphasize promising electrolyte systems based on sulfides and argyrodites, such as LiPS5Cl and β-Li3PS4, oxide electrolytes, bare and doped Li7La3Zr2O12 garnet, NASICON-type structures, and perovskite electrolyte materials. Moreover, we discuss the present and future challenges that all-solid-state batteries face for large-scale industrial applications.

“…For example, other approaches have been made to decrease the dead space between the active materials and the SEs as previously mentioned before by introducing the SE coatings on the surface of the active materials. [60,68] As shown in Figure 2d, Nakamura et al produced a uniform coating layer of Li 3 PS 4 (LPS) on the surface of LiNI 1/3 Co 1/3 Mn 1/3 O 2 (NCM) by using the dry coating methods. [68] During the coating process, unlike the other coating method which are complex and low efficiency, they made the core-shell particles which has SE shell and the active materials core by simple dry mixing of powder with mechanical forces.…”

tinuously verified via the development of solid electrolytes (SEs) and appropriate active materials, which have high ionic conductivities and high applicability to ASSLBs systems, respectively. Unlike conventional liquid LIBs, which utilize organic liquid electrolytes as lithium ions and electron transfer passages, ASSLBs use inorganic solid SEs for the same purposes. Thus, the ionic conductivities of SEs play a critical role in increasing electrochemical performance during cell tests. In this respect, the research approaches for SEs have mainly focused on increasing their ionic conductivities. Because of that reason, a variety of inorganic SEs have been developed (e.g., oxides, polymers, and sulfides). [7-13] Before 2010, the lithium ion conductivities of various SEs were much lower than the corresponding values of the liquid electrolytes. However, recent significant improvements in the ionic conductivities of SEs have resulted in novel designs of chemical elements, doping, and morphological control. [14-16] Among them, oxide, polymer, and sulfide SEs have been intensively developed because of their high ionic conductivities and mechanical advantages. [17-22] In particular, the recently developed sulfide SEs show high lithium ion conductivity, similar to the ionic conductivity of organic liquid electrolytes. Along with the development of SEs, much effort has been expended toward increasing the interfacial area and decreasing the side reactions between the SEs and the active materials via coatings and morphological control. [23-27] However, although the recently developed SEs have achieved high ionic conductivities, the electrochemical performance of the ASSLBs and power density have not reached commercialization standards compared to the case of conventional liquid LIBs. Given the low electrochemical performance of the ASSLBs in spite of the high ionic conductivities, the overall overpotential and electronic conductivity within the battery should be emphasized because it could affect the electrochemical performance during cell tests. Herein, we review recent progress in ASSLBs and their battery performance in terms of the materials and electrodes. In addition, we propose a future research direction for increasing the electrochemical performance and improving the overall overpotential property via novel electrode design. After the research that shows that Li 10 GeP 2 S 12 (LGPS)-type sulfide solid electrolytes can reach the high ionic conductivity at the room temperature, sulfide solid electrolytes have been intensively developed with regard to ionic conductivity and mechanical properties. As a result, an increasing volume of research has been conducted to employ all-solid-state lithium batteries in electric automobiles within the next five years. To achieve this goal, it is important to review the research over the past decade, and understand the requirements for future research necessary to realize the practical applications of all-solid-state lithium batteries. To date, research on all-solid-state lithium batt...

All-solid-state lithium batteries (ASSLBs) with nonflammable solid electrolytes (SEs) deliver greatly enhanced safety characteristics. Furthermore, ASSLBs composed of cathodes with high working voltages, such as LiCoO 2 , LiNi x Co y Mn z O 2 (x + y + z = 1, NCM), LiNi x Co y Al z O 2 (x + y + z = 1, NCA), LiMn x Fe y PO 4 (x + y = 1, LMFP), and LiNi 0.5 Mn 1.5 O 4 (LNMO), and a lithium metal anode can achieve comparable or better performance compared with that of LLBs in terms of energy density. Therefore, high-voltage ASSLBs have been regarded as the most promising next-generation batteries. Although significant progress has been achieved in high-voltage ASSLBs research, their development still faces multiple challenges. To facilitate further effective and target-oriented research on highvoltage ASSLBs, a summary of recent research progress is urgently needed. In this review, recent research progress in high-voltage ASSLBs is summarized from the perspectives of SEs modification, interfacial challenges and their corresponding solutions for cathodes, and high-voltage composite cathode design for practical applications. Finally, the authors' perspectives on the state of current ASSLBs research, aiming to propose possible research directions for the future development of high-voltage ASSLBs.
