“…The LATP main phase is interrupted by small amounts of secondary phases and residual porosity. Thereby, the grain growth with increasing temperature and the inclusion of intergranular pores are observed [378].…”

“…(v) Additives have been reported to improve the ionic conductivity of LATP. For example, the product obtained by sintering of a mixture of Li2.9B0.9S0.1O3.1 and LATP (mole ratio of 1:9) at 800 °C presented a total conductivity of 1.5 × 10 −5 S cm −1 at room-temperature [378]. (vi) Owing to its high Li + ion conductivity, LATP is an important ASSB ceramic electrolyte; however, when Li metal is used as the anode, the LATP membrane has to be separated from it using an additional protective layer to avoid the Ti 4+ /Ti 3+ reduction reaction, because the presence of this redox couple during electrochemical cycling leads to slow structural phase transitions and lowers the Li + ion conducting properties of the LATP electrolyte during cycling.…”

“…Waetzig et al [378] synthesized LATP using the sol-gel method followed by ball milling and further densification of the powders using the SPS technique. The LATP pellets sintered at 1000 • C presented the excellent room-temperature Li + ion conductivity of 1 × 10 −3 S cm −1 , bulk density of 2.92 g cm −3 , and relative density of 99.4%.…”

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.

The organic electrolyte in commercial liquid lithium‐ion batteries is volatile, prone to low‐temperature failure, has a declining safety performance at high temperatures, and is susceptible to serious side reactions with electrodes. The current research hotspots are solid‐state electrolytes with high energy densities and high safety performance. The next‐generation lithium metal solid‐state battery electrolyte is expected to be Li1+XAlXTi2‐X(PO4)3 (LATP) with a sodium superionic conductor (NASICON) structure due to its high ionic conductivity, high energy density, and good stability in air. This paper presents a review of the crystal structure of LATP, lithium‐ion diffusion channels, synthesis methods, factors affecting high ionic conductivity, and regulation and application of interfacial stability. This effectively addresses the problems of LATP in current applications and facilitates the promotion of all‐solid‐state batteries in future applications.This article is protected by copyright.

The use of all‐solid‐state lithium metal batteries (ASSLMBs) has garnered significant attention as a promising solution for advanced energy storage systems. By employing non‐flammable solid electrolytes in ASSLMBs, their safety profile is enhanced, and the use of lithium metal as the anode allows for higher energy density compared to traditional lithium‐ion batteries. To fully realize the potential of ASSLMBs, solid‐state electrolytes (SSEs) must meet several requirements. These include high ionic conductivity and Li+ transference number, smooth interfacial contact between SSEs and electrodes, low manufacturing cost, excellent electrochemical stability, and effective suppression of dendrite formation. This paper delves into the essential requirements of SSEs to enable the successful implementation of ASSLMBs. Additionally, the representative state‐of‐the‐art examples of SSEs developed in the past 5 years, showcasing the latest advancements in SSE materials and highlighting their unique properties are discussed. Finally, the paper provides an outlook on achieving balanced and improved SSEs for ASSLMBs, addressing failure mechanisms and solutions, highlighting critical challenges such as the reversibility of Li plating/stripping and thermal runaway, advanced characterization techniques, composite SSEs, computational studies, and potential and challenges of ASS lithium–sulfur and lithium–oxygen batteries. With this consideration, balanced and improved SSEs for ASSLMBs can be realized.
