“…While the specifics may vary depending on the exact method used and the composition of the HEA, the general principles involve exploiting the non-equilibrium conditions to produce metastable phases with unique properties. Currently, the HTS technique primarily focuses on solid-state reduction from precursors to products [ 21 ]. However, there is still room for improvement to enhance its versatility for different reaction systems and high-throughput screening and synthesis of catalysts.…”

Structural engineering of metastable nanomaterials with abundant defects has attracted extensive attention in energy-related fields. High-temperature shock (HTS) technique, as a rapid-developing and advanced synthesis strategy, offers significant potential for the rational design and fabrication of high-quality nanocatalysts in an ultrafast, scalable, controllable, and eco-friendly way. In this review, we provide an overview of various metastable micro-/nano- materials synthesized via HTS, including single metallic and bimetallic nanostructures, high entropy alloys, metal compounds (e.g. metal oxides), and carbon nanomaterials. Note that HTS provide a new research dimension for nanostructure, i.e. kinetic modulation. Furthermore, we summarize the application of HTS in structural engineering of 2D materials as supporting films for transmission electron microscopy (TEM) grids, which is vital for the direct imaging of metastable materials. Finally, we discuss the potential future applications of high-throughput and liquid-phase HTS strategies for non-equilibrium micro/nano-manufacturing beyond energy-related fields. It is believed that this emerging research field will bring new opportunities to the development of nanoscience and nanotechnology in both fundamental and practical aspects.

Cellulose‐based solid electrolyte possesses the characteristics of low cost, high strength, and sustainability, and has great potential in the field of solid‐state lithium metal batteries. However, the large hydrogen bonds between cellulose molecules make the molecular chains tightly arranged, and hinder the ion conduction, seriously limiting its further development. Herein, an ion‐conducting molecular grafting strategy is proposed for the fabrication of cellulose acetate quasi‐solid composite electrolyte (CLA‐CN‐LATP QCE) with a superior ionic conductivity of 1.25 × 10−3 S cm−1 at room temperature. Benefited from grafted functional molecules, the assembled symmetrical battery exhibits low polarization voltage and highly stable lithium stripping/plating cycling of more than 1200 h at 0.1 mA cm−2 current density. Moreover, it endows LFP|CLA‐CN‐LATP QCE|Li battery with excellent long‐cycle stability of 1500 cycles at 0.5 C and 25 °C and superior capacity retention of 92.1%. Importantly, this work provides an effective strategy for further opening the ion transport channel between cellulose molecular chains and improving the interface properties of electrolytes and electrodes.

Solid‐state lithium‐ion batteries (SSLIBs) have been considered as the priority candidate for next‐generation energy storage system, due to their advantages in safety and energy density compare with conventional liquid electrolyte systems. However, the introduction of numerous solid‐solid interfaces results in a series of issues, hindering the further development of SSLIBs. Therefore, a thorough understanding on the interfacial issues is essential to promote the practical applications for SSLIBs. In this review, the interface issues are discussed from the perspective of transportation mechanism of electrons and lithium ions, including internal interfaces within cathode/anode composites and solid electrolytes (SEs), as well as the apparent electrode/SEs interfaces. The corresponding interface modification strategies, such as passivation layer design, conductive binders, and thermal sintering methods, are comprehensively summarized. Through establishing the correlation between carrier transport network and corresponding battery electrochemical performance, the design principles for achieving a selective carrier transport network are systematically elucidated. Additionally, the future challenges are speculated and research directions in tailoring interfacial structure for SSLIBs. By providing the insightful review and outlook on interfacial charge transfer, the industrialization of SSLIBs are aimed to promoted.
