“…Meanwhile, the morphology did not exhibit any cracks, needles or holes in contrast with those that were heated for 5 and 20 hours. 195 Thus, the SSE thin lms can be produced in a crystalline form without the critical impact of post-annealing on lm morphology. Besides, the deposition of electrolyte (or its postannealing) at high temperatures on the electrode should be made carefully, taking into account the electrode material properties, avoiding interfacial problems, and preventing Li loss when the microcell is realized.…”

“…However, due to the larger size and mass of the ceramic particles the energy density of the ceramic particles in the case of the same anode material will be reduced compared to that of the liquid battery, or the solid battery using the polymer thin film solid electrolyte. [35,119] In addition, the thick solid electrolyte pellet also brings high impedance. Most of the oxide solid electrolytes have high rigidity and brittleness, which brings obstacles to the assembly of solid battery and the mass production of electrolyte sheets.…”

Solid electrolyte is a key component for all-solid-state lithium battery that is one of the most promising technologies for next-generation energy storages. This review describes the challenges and strategies, preparation methods and outlook of oxide solid electrolytes for solid-state lithium batteries. The general strategies on enhancing ionic conductivity of oxide solid electrolytes and reducing impedance interface are first summarized. We then introduce the basic structures of typical oxide electrolytes. The preparation technologies are also introduced for oxide electrolytes with various dimensions including bulk, thin film and fiber. In addition, the integration of oxide electrolytes with electrode materials is highlighted. In the last part, an outlook for the future development of oxide electrolytes towards practical applications is provided.

“…Amorphous thin-film of LLTO SSEs have an open and disordered structure and can be prepared using a chemical solution method, like the sol-gel process [88], or physical vapour deposition techniques, such as radio frequency (RF) magnetron sputtering, pulsed laser deposition (PLD), electron-beam (e-beam) evaporation, and spin coating [63].…”

Solid-state lithium metal batteries (LMBs) have become increasingly important in recent years due to their potential to offer higher energy density and enhanced safety compared to conventional liquid electrolyte-based lithium-ion batteries (LIBs). However, they require highly functional solid-state electrolytes (SSEs) and, therefore, many inorganic materials such as oxides of perovskite La2/3−xLi3xTiO3 (LLTO) and garnets La3Li7Zr2O12 (LLZO), sulfides Li10GeP2S12 (LGPS), and phosphates Li1+xAlxTi2−x(PO4)3x (LATP) are under investigation. Among these oxide materials, LLTO exhibits superior safety, wider electrochemical window (8 V vs. Li/Li+), and higher bulk conductivity values reaching in excess of 10−3 S cm−1 at ambient temperature, which is close to organic liquid-state electrolytes presently used in LIBs. However, recent studies focus primarily on composite or hybrid electrolytes that mix LLTO with organic polymeric materials. There are scarce studies of pure (100%) LLTO electrolytes in solid-state LMBs and there is a need to shed more light on this type of electrolyte and its potential for LMBs. Therefore, in our review, we first elaborated on the structure/property relationship between compositions of perovskites and their ionic conductivities. We then summarized current issues and some successful attempts for the fabrication of pure LLTO electrolytes. Their electrochemical and battery performances were also presented. We focused on tape casting as an effective method to prepare pure LLTO thin films that are compatible and can be easily integrated into existing roll-to-roll battery manufacturing processes. This review intends to shed some light on the design and manufacturing of LLTO for all-ceramic electrolytes towards safer and higher power density solid-state LMBs.
