“…However after sintering of composite, additional reflections appeared at 17.0°, 18.5°, 20.4°, 22.2°, 27.0°, 27.3°, 27.7°, 31.0° and 39.3°. They were identified as LiTiPO5 and Li4P2O7 phases [8,11,24,[27][28][29]33]. As evidenced by HTXRD studies, the most pronounced changes in phase composition could be observed above 700°C.…”

The existing solid electrolytes for lithium ion batteries suffer from low total ionic conductivity, which restricts its usefulness for the lithium-ion battery technology. Among them, the NASICON-based materials, such as Li1.3Al0.3Ti1.7(PO4)3 (LATP) exhibit low total ionic conductivity due to highly resistant grain boundary phase. One of the possible approaches to efficiently enhance their total ionic conductivity is the formation of a composite material. Herein, the Li2.9B0.9S0.1O3.1 glass, called LBSO hereafter, was chosen as an additive material to improve the ionic properties of the ceramic Li1.3Al0.3Ti1.7(PO4)3 base material. The properties of this Li1.3Al0.3Ti1.7(PO4)3-xLi2.9B0.9S0.1O3.1 (0  x  0.3) system have been studied by means of high temperature X-ray diffractometry (HTXRD), 7 Li, 11 B, 27 Al and 31 P magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR), thermogravimetry (TG), scanning electron microscopy (SEM), impedance spectroscopy (IS) and density methods. We show here that the introduction of the foreign LBSO phase enhances their electric properties. This study reveals several interesting correlations between the apparent density, the microstructure, the composition, the sintering temperature and the ionic conductivity. Moreover, the electrical properties of the composites will be discussed in the terms of the bricklayer model (BLM). The highest value of σtot = 1.5 × 10 −4 S•cm −1 has been obtained for LATP-0.1LBSO material sintered at 800°C.

“…Infiltration of LATP with ionic liquid (IL) increases the ionic conductivity, and the interaction between grain boundary and IL was held responsible for that [28]. Also, LiPO 3 and Li 2 SO 4 [29], Li 2.9 B 0.9 S 0.1 O 3.1 [30], and LiF [31] aid in increasing ionic conductivity.…”

Lithium aluminum titanium phosphate (LATP) is one of the materials under consideration as an electrolyte in future all-solid-state lithium-ion batteries. In ceramic processing, the presence of secondary phases and porosity play an important role. In a presence of more than one secondary phase and pores, image analysis must tackle the difficulties about distinguishing between these microstructural features. In this study, we study the phase evolution of LATP ceramics sintered at temperatures between 950 and 1100 ℃ by image segmentation based on energy-dispersive X-ray spectroscopy (EDS) elemental maps combined with quantitative analysis of LATP grains. We found aluminum phosphate (AlPO 4) and another phosphate phase ((Li x)P y O z). The amount of these phases changes with sintering temperature. First, since the grains act as an aluminum source for AlPO 4 formation, the aluminum content in the LATP grains decreases. Second, the amount of secondary phase changes from more (Li x)P y O z at 950 ℃ to mainly AlPO 4 at 1100 ℃ sintering temperature. We also used scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM) to study the evolution of the LATP grains and AlPO 4 , and LATP grain size increases with sintering temperature. In addition, transmission electron microscopy (TEM) was used for the determination of grain boundary width and to identify the amorphous structure of AlPO 4 .

With the increasing use of Li batteries for storage, their safety issues and energy densities are attracting considerable attention. Recently, replacing liquid organic electrolytes with solid‐state electrolytes (SSE) has been hailed as the key to developing safe and high‐energy‐density Li batteries. In particular, Li1+xAlxTi2−x(PO4)3 (LATP) has been identified as a very attractive SSE for Li batteries due to its excellent electrochemical stability, low production costs, and good chemical compatibility. However, interfacial reactions with electrodes and poor thermal stability at high temperatures severely restrict the practical use of LATP in solid‐state batteries (SSB). Herein, a systematic review of recent advances in LATP for SSBs is provided. This review starts with a brief introduction to the development history of LATP and then summarizes its structure, ion transport mechanism, and synthesis methods. Challenges (e.g., intrinsic brittleness, interfacial resistance, and compatibility) and corresponding solutions (ionic substitution, additives, protective layers, composite electrolytes, etc.) that are critical for practical applications are then discussed. Last, an outlook on the future research direction of LATP‐based SSB is provided.
