“…In addition, such high-rate performance of the FeS@PCSs-650 electrode is better than the previous work of FeS-based electrodes (Figure 4d). [31][32][33][38][39] Figure 4e displays the cycle performance of FeS@PCSs electrodes at 0.1 A g À 1 for LIBs. The Coulombic efficiency of FeS@PCSs-650 material is close to 100 % compared to other two samples.…”

To achieve high‐performance lithium‐ion batteries (LIBs), the ion diffusion behavior in electrode materials is a challenging issue. Herein, 2D FeS/porous carbon nanosheets (FeS@PCSs) hybrids were successfully prepared by a facile, low‐cost strategy involving metal salt‐assisted chemical vapor deposition (CVD) and in situsulfuration process. The unique 2D structure is conducive to shorten the ion diffusion distance, buffer the volume change of FeS nanoparticles, as well as provide abundant sites for Li+ storage. Benefiting from the unique structure, the FeS@PCSs electrode exhibits high surface reaction contributions. When investigated as an anode for lithium‐ion batteries, the as‐prepared FeS@PCSs electrode exhibits a high reversible capacity (1026.2 mAh g−1 at 0.1 A g−1), excellent rate capability (647.2 mAh g−1 at 5 A g−1 and 561.1 mAh g−1 at 10 A g−1), and outstanding cycling stability (888.7 mAh g−1 at 1.0 A g−1 over 800 cycles). This work provides a cost‐effective and scalable route to synthesis the 2D carbon‐based transition metal compounds as high‐performance LIBs anodes.

“…This can be attributed to the viscosity of CMC and SA is much lower than that of PVDF, which contributes to the uniform dispersion of the particles and effective release of the stress . Similar to conductive additives, the choice of binders is also diverse (e.g., PVDF cathode /CMC anode , PVDF cathode /SA anode , and CMC cathode /SA anode ) depending on the type of electrode material in the process of constructing a full cell.…”

With ever‐increasing efforts focused on basic research of sodium‐ion batteries (SIBs) and growing energy demand, sodium‐ion full cells (SIFCs), as unique bridging technology between sodium‐ion half‐cells (SIHCs) and commercial batteries, have attracted more and more interest and attention. To promote the development of SIFCs in a better way, it is essential to gain a systematic and profound insight into their key issues and research status. This Review mainly focuses on the interface issues, major challenges, and recent progresses in SIFCs based on diversified electrolytes (i.e., nonaqueous liquid electrolytes, quasi‐solid‐state electrolytes, and all‐solid‐state electrolytes) and summarizes the modification strategies to improve their electrochemical performance, including interface modification, cathode/anode matching, capacity ratio, electrolyte optimization, and sodium compensation. Outlooks and perspectives on the future research directions to build better SIFCs are also provided.
