“…One unfortunate attribute of this LSTZ material is that it requires a sintering temperature of 1300 • C, which is too high to be compatible with electrode materials in cases of co-sintering. In an effort to reduce the processing temperature, Yu et al [213] formulated Li 3/8 Sr 7/16 Nb 3/4 Zr 1/4 O 3 (LSNZ), which can be sintered at 1200 • C, but showed reduced total conductivity (2 × 10 −5 S/cm at 30 • C). La doping to Sr sites could lead to a slight increase in the conductivity.…”

All-solid-state batteries (SSBs) are one of the most fascinating next-generation energy storage systems that can provide improved energy density and safety for a wide range of applications from portable electronics to electric vehicles. The development of SSBs was accelerated by the discovery of new materials and the design of nanostructures. In particular, advances in the growth of thin-film battery materials facilitated the development of all solid-state thin-film batteries (SSTFBs)—expanding their applications to microelectronics such as flexible devices and implantable medical devices. However, critical challenges still remain, such as low ionic conductivity of solid electrolytes, interfacial instability and difficulty in controlling thin-film growth. In this review, we discuss the evolution of electrode and electrolyte materials for lithium-based batteries and their adoption in SSBs and SSTFBs. We highlight novel design strategies of bulk and thin-film materials to solve the issues in lithium-based batteries. We also focus on the important advances in thin-film electrodes, electrolytes and interfacial layers with the aim of providing insight into the future design of batteries. Furthermore, various thin-film fabrication techniques are also covered in this review.

“…In the past few years, several types of inorganic solid electrolytes have been explored, such as perovskite type electrolytes 74 , garnet based electrolytes 75 and sulfurized based electrolytes 76 . However, among these electrolytes, garnet electrolyte is the most favored because of its high ionic conductivity, wide electrochemical window, thermodynamic and electrochemical stability.…”

The applications of lithium-ion batteries have been limited because their energy density can no longer meet the requirements of an emerging energy society. Lithium metal batteries (LMBs) are being considered as potential candidate for nextgeneration energy storage systems owing to the high theoretical specific capacity and low electrochemical potential of lithium metal. However, the commercialization of LMB is limited due to several challenges, such as uncontrollable formation of dendrites, unstable solid electrolyte interface, and infinite anode volume change, which can lead to grievous catastrophe. In this study, several typical mechanisms of lithium dendrite formation and growth are summarized. The results suggest that a smaller current density, greater Li + transference number, higher mechanical strength of the electrolyte, and a more homogeneous distribution of Li + on the substrate are conducive to the uniform deposition morphology of lithium metal. In view of these results, combined with the researches on LMBs conducted in recent years, composite anodes can be summarized into three level from internal to external. (i) Internal composite of lithium metal anode: the scaffolds composited with lithium metal are classified as non-conductive (NC), electron-conductive (EC), ion-conductive (IC), and mixed ion and electron-conductive (MIEC) scaffolds. Composited with NC scaffolds, the tip effect can be weakened through the interaction between polar functional groups and Li + . The composite of lithium metal and EC scaffolds can effectively reduce the local current density, while IC scaffolds can increase the ion flux. However, the performance of LMBs may be hindered by the insulation of electrons or Li + at high rates. In comparison, MIEC scaffolds can provide fast ion/electron transfer channels for the deposition or dissolution of lithium metal, which is beneficial for the electrochemical performance of LMBs even at high rates. (ii) Internal composite of LMB: Compared with liquid electrolytes, solid-state electrolytes (SSEs) and quasi-solid-state electrolytes are much safer. However, their interfacial contact with lithium metal anodes has been seriously criticized. Lithium metal anodes can be composited with SSEs or quasi-solid-state electrolytes to optimize the interface contact performance and reduce the interface resistance, thereby promoting the development of solid-state batteries. (iii) Composite of internal environment and external operating conditions: Composited with external physical fields, such as electric fields, magnetic fields, and temperature fields, the distribution of Li + can be homogeneous and the initial nucleation process can be regulated. Overall, this review summarizes several composite anodes that have greatly optimized the performance of LMBs and highlights the potential of multi-level composites for applications in lithium metal anodes.

“…In addition, the direct stacking of solid-state cells in one packing provides high operating voltage and is favorable for vehicle applications . Usually solid electrolytes (SEs) are classified into different types, namely, oxide-type (NASICON-type, , perovskite-type, garnet-type, etc.) and sulfide-type (thio-LISICON, − argyrodite-type, , etc.).…”

A new silver halide-doped Li 7 P 3 S 11 (7Li 2 S−3P 2 S 5 ) solid electrolyte with increasing ionic conductivity and stability was prepared by the wet ball milling process. Detailed structural investigations were carried out after the doping process. First, AgI was added to a Li 7 P 3 S 11 solid electrolyte to achieve a novel composite/phase. The highest ionic conductivity of the composite was optimized by changing the AgI concentration (0.05, 0.10, and 0.25) and the sintering temperature (240, 270, and 300 °C). The selected Li 7 Ag 0.1 P 3 S 11 I 0.1 solid electrolyte displayed a high ionic conductivity of 1.35 × 10 −3 S cm −1 at room temperature, which is higher than the prepared pristine Li 7 P 3 S 11 solid electrolyte. High-power X-ray diffraction analysis is used to analyze the crystalline nature of the electrolyte. The surface morphology of the electrolyte was studied by the field-emission microscopy technique. The surface functional group of the Li 7 Ag 0.1 P 3 S 11 I 0.1 solid electrolyte was analyzed by the X-ray photoelectron spectroscopy technique. The electrochemical behavior of the selected electrolyte was analyzed by cyclic voltammetry, DC polarization, and impedance spectroscopy techniques. Cyclic voltammetry and DC polarization showed that the synthesized Li 7 Ag 0.1 P 3 S 11 I 0.1 solid electrolyte is highly stable up to 5 V potential window and has charge−discharge stability of more than 100 cycles against Li metal.
