“…Lee et al [154] demonstrated a silver/carbon composite anode that could mitigate the problems of low CE and dendrite growth in ASSLBs at high current densities. It was proved by cross-sectional SEM and corresponding energy dispersive spectroscopy that nano-Ag particles can be alloyed with Li during the process of Li plating.…”

“…Consequently, the ASSLBs configured with Al 2 O 3 -coated-Li/sulfide membrane/NCM exhibited capacity retention of 80.2% after 150 cycles with a high NCM mass loading of 11.6 mg cm -2 at 0.05 C [Figure 19B and C]. Moreover, Samsung fabricated a thin sulfide film using a doctor blade [154] . By modifying the composition and structure of anode and cathode, a 900 Wh L -1 level ASSLBs with superior cycle life (> 1000 times) was obtained.…”

Solid electrolytes are recognized as being pivotal to next-generation energy storage technologies. Sulfide electrolytes with high ionic conductivity represent some of the most promising materials to realize high-energy-density all-solid-state lithium batteries. Due to their soft nature, sulfides possess good wettability against Li metal and their preparation process is relatively effortless. High cell-level sulfide-based all-solid-state lithium batteries have gradually been realized in recent years. However, there are still several disadvantages that sulfide electrolytes need to overcome, including their sensitivity to humid air and instability to electrodes. Herein, the recent progress for sulfide electrolytes, with particular attention given to electrolyte synthesis mechanisms, electrochemical and chemical stability, interphase stabilization and all-solid-state lithium batteries with high cell-level energy density, is presented.

“…[9] Owing to above issues, most of reported sulfide-based ASSLBs exhibit limited cycle stability (less than 200 cycles) and low capacity retention, which is far away from practical application. Only very recently, Ye et al [10] and Tan et al [11] enabled stably cycle of sulfide-based ASSLBs with transitional metal oxide cathodes by applying a coating layer and a high axial pressure simultaneously. Accordingly, it is imperative to alleviate the interfacial issues of sulfide-based ASSLBs and improve the cycle stability by a facile method.…”

Sulfide solid electrolytes with high conductivity that is close to that of liquid electrolyte have been considered to be one of the most promising electrolytes for all‐solid‐state lithium batteries (ASSLBs). Unfortunately, the narrow electrochemical windows of sulfide electrolyte and contact loss at the interface upon cycles much limits the application of sulfide‐based ASSLBs. In this work, an organic quinone cathode, 5,7,12,14‐pentacenetetrone (PT), is used to fabricate an ASSLB with a sulfide electrolyte of glass ceramic 70Li2S‐30P2S5 (LPS). Based on the various in situ/ex situ analyses, it is successfully demonstrated that the decomposition of LPS is negligible and the corresponding effects on interfacial impedance are reversible with optimized carbon additives. In addition, the inherent low Young's modulus of the PT electrode efficiently prevents the contact loss at the interface. As a result, the PT‐based ASSLBs deliver a high specific capacity (312 mAh g−1) and an excellent capacity retention (90.6%) over 500 cycles which is superior to previous reports. Moreover, a carbon‐free ASSLB is constructed by employing Mo6S8 as conductive additives in a PT‐based cathode, which shows an improved rate performance and a long life.

“…Since then, a lot of effort has been directed to improving the electrochemical performance of lithium-ion batteries [ 2 ]. One of the perspective methods of stabilizing lithium-ion battery electrochemical characteristics and safety is to apply solid-state inorganic electrolyte instead of liquid organic electrolyte as the traditional electrolyte for commercial lithium-ion batteries [ 3 , 4 , 5 , 6 , 7 ]. Some solid-state electrolytes have high ionic conductivity in an order of magnitude of ~10 −3 S·cm −1 [ 8 ] in comparison to liquid electrolyte [ 9 ].…”

Solid-state reaction was used for Li7La3Zr2O12 material synthesis from Li2CO3, La2O3 and ZrO2 powders. Phase investigation of Li7La3Zr2O12 was carried out by x-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS) methods. The thermodynamic characteristics were investigated by calorimetry measurements. The molar heat capacity (Cp,m), the standard enthalpy of formation from binary compounds (ΔoxHLLZO) and from elements (ΔfHLLZO), entropy (S0298), the Gibbs free energy of the Li7La3Zr2O12 formation (∆f G0298) and the Gibbs free energy of the LLZO reaction with metallic Li (∆rGLLZO/Li) were determined. The corresponding values are Cp,m = 518.135 + 0.599 × T − 8.339 × T−2, (temperature range is 298–800 K), ΔoxHLLZO = −186.4 kJ·mol−1, ΔfHLLZO = −9327.65 ± 7.9 kJ·mol−1, S0298 = 362.3 J·mol−1·K−1, ∆f G0298 = −9435.6 kJ·mol−1, and ∆rGLLZO/Li = 8.2 kJ·mol−1, respectively. Thermodynamic performance shows the possibility of Li7La3Zr2O12 usage in lithium-ion batteries.
