    Engineering energy dense electrodes (e.g. lithium metal, conversion cathodes, etc.) with solid electrolytes is important for enhancing the practical energy density of solid-state batteries. However, large electrode volumetric strain can cause significant drive fracture, delamination, and accelerate degradation. This review discusses transport and chemo-mechanical challenges associated with energy dense solid state batteries. In particular, this review focuses on summarizing work which provides design strategies for implementation on energy dense anodes with rigid solid electrolytes. This review further assesses the properties which impact the elasticity of inorganic solid electrolytes and inorganic/organic hybrid electrolyte. Finally, this review discusses the advanced characterization approaches for analyzing the coupled electrochemistry/transport/mechanical phenomena that occur at buried solid-solid interfaces

  2. The cold sintering process (CSP) is a low-temperature consolidation method used to fabricate materials and their composites by applying transient solvents and external pressure. In this mechano-chemical process, the local dissolution, solvent evaporation, and supersaturation of the solute lead to “solution-precipitation” for consolidating various materials to nearly full densification, mimicking the natural pressure solution creep. Because of the low processing temperature (<300°C), it can bridge the temperature gap between ceramics, metals, and polymers for co-sintering composites. Therefore, CSP provides a promising strategy of interface engineering to readily integrate high-processing temperature ceramic materials (e.g., active electrode materials, ceramic solid-state electrolytes) as “grains” and low-melting-point additives (e.g., polymer binders, lithium salts, or solid-state polymer electrolytes) as “grain boundaries.” In this minireview, the mechanisms of geomimetics CSP and energy dissipations are discussed and compared to other sintering technologies. Specifically, the sintering dynamics and various sintering aids/conditions methods are reviewed to assist the low energy consumption processes. We also discuss the CSP-enabled consolidation and interface engineering for composite electrodes, composite solid-state electrolytes, and multi-component laminated structure battery devices for high-performance solid-state batteries. We then conclude the present review with a perspective on future opportunities and challenges.

  3. Abstract Over the past decade, solid‐state batteries have garnered significant attentions due to their potentials to deliver high energy density and excellent safety. Considering the abundant sodium (Na) resources in contrast to lithium (Li), the development of sodium‐based batteries has become increasingly appealing. Sulfide‐based superionic conductors are widely considered as promising solid eletcrolytes (SEs) in solid‐state Na batteries due to the features of high ionic conductivity and cold‐press densification. In recent years, tremendous efforts have been made to investigate sulfide‐based Na‐ion conductors on their synthesis, compositions, conductivity, and the feasibility in batteries. However, there are still several challenges to overcome for their practical applications in high performance solid‐state Na batteries. This article provides a comprehensive update on the synthesis, structure, and properties of three dominant sulfide‐based Na‐ion conductors (Na3PS4, Na3SbS4, and Na11Sn2PS12), and their families that have a variety of anion and cation doping. Additionally, the interface stability of these sulfide electrolytes toward the anode is reviewed, as well as the electrochemical performance of solid‐state Na batteries based on different types of cathode materials (metal sulfides, oxides, and organics). Finally, the perspective and outlook for the development and practical utilization of sulfide‐based SE in solid‐state batteries are discussed.

  4. Abstract Rechargeable solid‐state sodium metal batteries (SSMBs) experience growing attention owing to the increased energy density (vs Na‐ion batteries) and cost‐effective materials. Inorganic sulfide‐based Na‐ion conductors also possess significant potential as promising solid electrolytes (SEs) in SSMBs. Nevertheless, due to the highly reactive Na metal, poor interface compatibility is the biggest obstacle for inorganic sulfide solid electrolytes such as Na3SbS4to achieve high performance in SSMBs. To address such electrochemical instability at the interface, new design of sulfide SE nanostructures and interface engineering are highly essential. In this work, a facile and straightforward approach is reported to prepare 3D sulfide‐based solid composite electrolytes (SCEs), which utilize porous Na3SbS4(NSS) as a self‐templated framework and fill with a phase transition polymer. The 3D structured SCEs display obviously improved interface stability toward Na metal than pristine sulfide. The assembled SSMBs (with TiS2or FeS2as cathodes) deliver outstanding electrochemical cycling performance. Moreover, the cycling of high‐voltage oxide cathode Na0.67Ni0.33Mn0.67O2(NNMO) is also demonstrated in SSMBs using 3D sulfide‐based SCEs. This study presents a novel design on the self‐templated nanostructure of SCEs, paving the way for the advancement of high‐energy sodium metal batteries.

  5. Solid-state sulfur cathodes based on inorganic sulfide solid electrolytes can enable energy-dense lithium batteries. However, volume changes and chemical decomposition can drive delamination and degradation during cycling. To overcome these challenges, this paper reports an in situ approach to encapsulate the solid-state sulfur cathode with a gel polymer electrolyte (GPE). The GPE is covalently bonded with the sulfide solid electrolyte and acts as a barrier that suppresses chemical decomposition between the sulfide solid electrolyte and cathode active material. The elastic GPE maintains interfacial contact within the sulfur cathode allowing for greater sulfur utilization. The solid-state sulfur cathode with GPE demonstrates capacities nearing 700 mAh g −1 and capacity retention over 100 cycles.
