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.

“…Materials with outstanding compatibility of organic and inorganic phases are considered ideal modified layers on inorganic fillers, such as polydopamine [99] and PMMA. [154] In addition, components with a similar structure to polymer matrix were utilized as the modified materials oninorganic fillers. For example, a chemical bonding interaction was constructed between polyethylene glycol (PEG) and Li 10 GeP 2 S 12 (LGPS) via the connection by (3chloropropyl)trimethoxysilane (CTMS), [155] as shown in Figure 7b.…”

Solid lithium batteries (SLBs) have received much attention due to their potential to achieve secondary batteries with high energy density and high safety. The solid electrolyte (SE) is believed to be the essential material for SLBs. Among the recent SEs, composite electrolytes have good interfacial compatibility and customizability, which have been broadly investigated as promising contenders for commercial SLBs. The high Li+ transference number (t Li+ ${{_{{\rm Li}{^{+}}}}}$ ) of composite electrolytes is critically important concerning the power/energy density and cycling life of SLBs, however, which is often overlooked. This Review presents a current opinion on the key factors in high t Li+ ${{_{{\rm Li}{^{+}}}}}$ composite electrolytes, including polymers, Li‐salts, inorganic fillers, and additives. Various strategies concerning providing a continuous pathway for Li‐ions and immobilizing anions via component interaction are discussed. This Review highlights the major obstacles hindering the development of high t Li+ ${{_{{\rm Li}{^{+}}}}}$ composite electrolytes and proposes future research directions for developing composite electrolytes with high t Li+ ${{_{{\rm Li}{^{+}}}}}$ .

“…The LATP SSE has been reported to be utilized in solid-state Li-ion, Li–S and Li–O 2 batteries. − However, there are still some obstacles restricting the practical implementation of LATP in SSLBs, including (1) irreversible reactivity of LATP with a Li metal anode due to a Ti 4+ /Ti 3+ redox couple, , (2) difficulty to obtain LATP with high density and satisfied Li + conductivity, and (3) poor solid–solid interfacial contact between the LATP and electrode due to hard and brittle features of the LATP ceramic. , To address the latter challenges, a composite solid electrolyte (CSE) composed of a polymer electrolyte, inorganic ceramic electrolyte filler, and some lithium salt is proposed. In a CSE, a polymer electrolyte is used to provide a soft interfacial contact with the electrode and better flexibility, and the inorganic ceramic phase guarantees sufficient ionic conductivity and electrochemical stability. − Yang et al prepared a CSE with vertically aligned and connected LATP nanoparticles in a poly(ethylene oxide) (PEO) matrix, which exhibits a Li + conductivity of 0.52 × 10 –4 S cm –1 at room temperature (RT) . Wang and co-workers embedded LATP ceramic into a PVDF-HFP polymer matrix to fabricate a CSE, and an ionic conductivity of 2.3 × 10 –4 S cm –1 at RT was obtained .…”

Surface functionalization is an effective strategy to reduce the chemical reactivity between a Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) electrolyte and Li metal anode and optimize the interfacial contact of different components. Herein, sodium itaconate (SI) is introduced to modify the surfaces of LATP particles (LATP@SI) via a self-polymerizing process, and a composite solid electrolyte (CSE) composed of poly(ethylene oxide) (PEO) and LATP@SI is fabricated. Benefiting from the protection of the SI nanolayer, LATP demonstrates chemical compatibility with the Li metal anode, while the reduced surface energy renders a good dispersion of LATP in PEO. Furthermore, abundant carboxyl groups in SI can offer a bridge between LATP and PEO to accelerate Li + transmission. As a result, the as-prepared PEO-LATP@SI-6 CSE exhibits a high ionic conductivity of 1.15 × 10 −4 S cm −1 at 30 °C and 1.20 × 10 −3 S cm −1 at 60 °C, a wide electrochemical stable window beyond 5.0 V, an improved Li + transference number of 0.41, and an optimized lithium compatibility over 1200 h with Li dendrite free. The as-assembled Li||PEO-LATP@SI-6 CSE||LiFePO 4 full battery delivers a high reversible capacity of 155 mAh g −1 and an outstanding capacity retention of 89% after 200 cycles. The Li|| LiFePO 4 pouch cell also successfully runs 50 cycles with a terminal discharge capacity of 116.6 mA h g −1 . This study opens a new avenue to protect LATP. The developed surface functionalization technique promises a facile and efficient method for interfacial engineering to accelerate the practical application of LATP in solid-state lithium batteries.
