Summary: Due to their high energy density and environmental friendliness, lithium-ion batteries (LIBs) have been widely used in electric vehicles, energy storage systems, and other devices. However, the traditional LIBs with liquid electrolytes (LEs) pose safety hazards. In order to achieve higher safety and energy density, researchers are exploring the use of solid-state electrolytes (SSEs) instead. This review comprehensively summarizes the behaviors, properties, and mechanisms of interfaces in all-solid-state lithium batteries with various sulfide SSEs, as well as recent research progress on characterization methods and designs to stabilize interfaces. Outlooks, challenges, and possible interface engineering strategies are also discussed.

Summary: The design of composite sulfur cathode is crucial for determining the physical and chemical properties of all-solid-state lithium-sulfur batteries (ASSLSBs), and the selection of solid-state electrolyte in the composite sulfur cathode is rarely studied. By comparing three typical sulfide solid-state electrolytes, the excellent compatibility between Li7P(3)S(11) electrolyte and sulfur cathode is revealed. The ASSLSBs based on Li7P(3)S(11) electrolytes exhibit fast reaction kinetics and high electrochemical stability, contributing to chemical congruency. These findings provide guidance for developing high-energy-density ASSLSBs.

Summary: Despite being one of the most mature battery technologies, lithium-ion batteries still face challenges in energy density, current density, safety, environmental compatibility, and cost. All-solid-state lithium batteries (ASSLB) based on lithium metal anodes have emerged as a promising solution, with 2D materials (2DM) playing a crucial role in improving their performance. Strategies for enhancing ASSLBs using 2DM have been categorized based on their application in the three main components: anode, cathode, and electrolyte. Advanced characterization techniques, such as in situ characterization and synchrotron X-ray techniques, are key for understanding the mechanisms of 2DM in ASSLBs.

Summary: Deformable, fast-ion conducting sulfides make it possible to create bulk-type solid-state batteries that can rival current Li-ion batteries in terms of energy density and scalability. One way to optimize the energy density of these batteries is to minimize the size of the electrolyte layer by integrating the solid electrolyte into thin membranes. However, it is difficult to prepare or integrate additive-free thin membranes or membranes based on preprepared scaffolds on a large scale. In this study, a scalable solution-based approach is proposed to produce glass microfiber-reinforced composites that restore the deformability of sulfide electrolytes and can easily be shaped into thin membranes through cold pressing. This approach enables easy preparation and enhances the energy density of sulfide-based solid-state batteries.

Summary: The rock-salt phase (RSP) formed on the surface of Ni-rich layered cathodes in liquid-electrolyte lithium-ion batteries is considered electrochemically inactive. However, in sulfide based all solid state batteries (ASSBs), massive RSP forms in the interior of LiNixMnyCo(1_x-y)O2 (NMC) crystals and remains electrochemically active even after long cycles. The tensioned layered phase in ASSBs allows lithium to be squeezed out of RSPs by compressive stress, rendering the RSPs electrochemically active. This discovery enables the development of high energy density and durable ASSBs.

Summary: Sulfide electrolyte-based all-solid-state batteries (ASSBs) are explored for their low temperature (LT) performance, with a focus on LiNi0.8Co0.1Mn0.1O2 (NCM811)|Li9.54Si1.74P1.44S11.7Cl0.3 (LiSPSCl)|Li4Ti5O12 (LTO) ASSBs. Charging the ASSB to 6 V at -40 degrees C resulted in a higher capacity of 100.7 mAh center dot g(-1) at 20 mA center dot g(-1) compared to charging to 4.3 V (-40 degrees C, 4.6 mAh center dot g-1). Thinner electrolytes are found to be favorable for LT operation due to reduced ion transfer distance. This study provides new strategies for boosting the capacity and energy density of sulfide-based ASSBs at LT for dedicated applications.

Summary: Lithium-sulfur (Li-S) batteries are considered one of the most promising future batteries due to their high theoretical energy density (2600 W center dot h center dot kg(-1)) and use of inexpensive active materials (elemental sulfur). Recent advancements in fundamental research and engineering, particularly in electrode, electrolyte, membrane, binder, and current collector, have significantly improved the performance of Li-S batteries from the laboratory level to practical application. However, safety concerns still need attention in the upcoming stage of application. This review focuses on the development of electrolytes for Li-S batteries from liquid to solid state, and highlights issues such as soluble lithium polysulfide migration, electrolyte ionic conductivity, electrolyte-electrode interface contact, and reaction kinetics. Furthermore, future perspectives on safe and high-performance Li-S batteries are also discussed.

Summary: All-solid-state lithium batteries (ASSLBs) with sulfide solid electrolytes (SSEs) have gained attention for their high safety and energy density. Ni-rich layered oxide cathode materials show promise in ASSLBs due to their high voltage, reversible capacity, and low cost. However, their performances, especially long-life capacity, are insufficient for electric vehicles. This review summarizes the issues of physical connection, chemical/electrochemical reactions, and space-charge layer (SCL) of Ni-rich layered oxide cathodes in ASSLBs with SSEs, as well as the modification strategies to address these issues. The future development direction of ASSLBs using Ni-rich oxide cathodes and SSEs is also discussed briefly.
