“…Constructing a buffer layer on Ni-rich oxide cathodes is also proved to be effective to enhance electrochemical performance. Recently, Li et al [177] successfully prepared LiNbO 3 -coated NCM811 cathodes, with 1 wt.% LiNbO 3 -coated NCM811 cathodes demonstrated a high initial discharge capacity of 203 mAh g -1 and excellent rate performance. Peng et al [178] carried out an in-depth investigation on coating LiNi 0.7 Co 0.1 Mn 0.2 O 2 (NCM712) with LiNbO 3 .…”

Solid electrolytes are recognized as being pivotal to next-generation energy storage technologies. Sulfide electrolytes with high ionic conductivity represent some of the most promising materials to realize high-energy-density all-solid-state lithium batteries. Due to their soft nature, sulfides possess good wettability against Li metal and their preparation process is relatively effortless. High cell-level sulfide-based all-solid-state lithium batteries have gradually been realized in recent years. However, there are still several disadvantages that sulfide electrolytes need to overcome, including their sensitivity to humid air and instability to electrodes. Herein, the recent progress for sulfide electrolytes, with particular attention given to electrolyte synthesis mechanisms, electrochemical and chemical stability, interphase stabilization and all-solid-state lithium batteries with high cell-level energy density, is presented.

“…[ 169 ] Moreover, the ionic conductivity of SCEs is highly dependent on the temperature, which shows a decreasing trend in ionic conductivity at sub‐zero temperatures. [ 170 ] Lower ionic conductivity cannot meet the operation requirement of EES devices at low temperatures. In the future, the enhancement of the low‐temperature ionic conductivity is the key to achieving the application of SCEs at low temperatures.…”

The operation of electrochemical energy storage (EES) devices at low temperatures as normal as at room temperature is of great significance for their lowtemperature environment application. However, such operation is plagued by the sluggish ions transport kinetics, which leads to the severe capacity decay or even failure of devices at low-temperature conditions. In this review, the difficulties of ions transport in electrolyte, electrolyte/electrode interface, and electrode material at low temperatures are discussed in depth, and the reported strategies to solve the corresponding problems are surveyed subsequently. Finally, the views on how to build high-performance low-temperatureavailable EES devices as well as their development directions are put forward.

“…LiNbO 3 -coating has been found to be a useful strategy to improve stability of electrode materials [68,69]. Recently, the electrochemical behavior of LiNbO 3 coating on LiNi 0.7 Co 0.1 Mn 0.2 O 2 electrode (LNO@NCM712) have been studied (Figure 9) [70]. The LNO@NCM712 electrode delivers initial discharge capacities of 80.9 and 138.9 mAh/g at 5 C under RT and 60 • C respectively.…”

Lithium niobate (LiNbO3) crystals are important dielectric and ferroelectric materials, which are widely used in acoustics, optic, and optoelectrical devices. The physical and chemical properties of LiNbO3 are dependent on microstructures, defects, compositions, and dimensions. In this review, we first discussed the crystal and defect structures of LiNbO3, then the crystallization of LiNbO3 single crystal, and the measuring methods of Li content were introduced to reveal reason of growing congruent LiNbO3 and variable Li/Nb ratios. Afterwards, this review provides a summary about traditional and non-traditional applications of LiNbO3 crystals. The development of rare earth doped LiNbO3 used in illumination, and fluorescence temperature sensing was reviewed. In addition to radio-frequency applications, surface acoustic wave devices applied in high temperature sensor and solid-state physics were discussed. Thanks to its properties of spontaneous ferroelectric polarization, and high chemical stability, LiNbO3 crystals showed enhanced performances in photoelectric detection, electrocatalysis, and battery. Furthermore, domain engineering, memristors, sensors, and harvesters with the use of LiNbO3 crystals were formulated. The review is concluded with an outlook of challenges and potential payoff for finding novel LiNbO3 applications.
