“…When we prepare the manuscript, Niu et al report their results that applying amorphous FeVO 4 as anode for KIBs. Although the amorphous FeVO 4 shows fast rate ability of ≈180 mAh g −1 at 2 A g −1 and relatively stable cycling, the amorphous microparticles synthesized by the ball‐milling method still inevitably face the challenges of the severe aggregation, the low ionic and electric conductivity as well as the large volume expansion and pulverization/inactivation during long‐time cycling . To resolve these issues, it would be an effective strategy to develop stable nanostructured transition metal vanadate based hybrid nanostructure to further boost its electrochemical performance for KIBs.…”

Developing low‐cost, high‐capacity, high‐rate, and robust earth‐abundant electrode materials for energy storage is critical for the practical and scalable application of advanced battery technologies. Herein, the first example of synthesizing 1D peapod‐like bimetallic Fe2VO4 nanorods confined in N‐doped carbon porous nanowires with internal void space (Fe2VO4⊂NC nanopeapods) as a high‐capacity and stable anode material for potassium‐ion batteries (KIBs) is reported. The peapod‐like Fe2VO4⊂NC nanopeapod heterostructures with interior void space and external carbon shell efficiently prevent the aggregation of the active materials, facilitate fast transportation of electrons and ions, and accommodate volume variation during the cycling process, which substantially boosts the rate and cycling performance of Fe2VO4. The Fe2VO4⊂NC electrode exhibits high reversible specific depotassiation capacity of 380 mAh g−1 at 100 mA g−1 after 60 cycles and remarkable rate capability as well as long cycling stability with a high capacity of 196 mAh g−1 at 4 A g−1 after 2300 cycles. The first‐principles calculations reveal that Fe2VO4⊂NC nanopeapods have high ionic/electronic conductivity characteristics and low diffusion barriers for K+‐intercalation. This study opens up new way for investigating high‐capacity metal oxide as high‐rate and robust electrode materials for KIBs.

“…The 2D MXenes (Ti 3 CNT z ) could exhibit a 1st discharge capacity of 710 mAh g −1 at 20 mA g −1 , but with a poor initial Coulombic efficiency of 28.4% . Other recently explored anode materials are layered K 2 V 3 O 8 , K 0.23 V 2 O 5 , and amorphous FeVO 4 , where the amorphous FeVO 4 anode could deliver a fast rate performance of 180 mA h g −1 at 2 A g −1 with a prolonged cycling life of 2000 cycles . A binder‐free SnO 2 nanosheets directly grown on stainless steel mesh demonstrated a specific capacity of 351 mAh g −1 over 100 cycles at 50 mA g −1 .…”

Demand for energy in day to day life is increasing exponentially. However, existing energy storage technologies like lithium ion batteries cannot stand alone to fulfill future needs. In this regard, potassium ion batteries (KIBs) that utilize K ions in their charge storage mechanism have attracted considerable attention due to their unique properties and are therefore established as one of the future battery systems of interest among the scientific community. Nevertheless, the development and identification of appropriate electrode materials is very essential for practical applications. This review features the current development in KIBs electrode and electrolyte materials, the present challenges facing this technology (in the commercial aspect), and future aspects to develop fully functional KIBs. The potassium storage mechanisms, evolution of the KIBs, and the advantages and disadvantages of each category of materials are included. Additionally, various approaches to enhance the electrochemical performances of KIBs are also discussed. This review is not only an amalgamation of different viewpoints in literature, but also contains concise perspectives and strategies. Moreover, the potential emergence of a novel class of K‐based dual ion batteries is also analyzed for the first time.

“…Metal oxides have been widely studied in LIBs and SIBs [152][153][154], however, their applications in PIBs are rarely reported. The reason can be attributed to the sluggish ion diffusion kinetics and poor structural stability [155,156]. To resolve the above issues, 1D and 2D metal oxides with abundant active sites, large surface area, and short ion diffusion path have caught the attention of researchers.…”

Potassium-ion batteries (PIBs) are appealing alternatives to conventional lithium-ion batteries (LIBs) because of their wide potential window, fast ionic conductivity in the electrolyte, and reduced cost. However, PIBs suffer from sluggish K + reaction kinetics in electrode materials, large volume expansion of electroactive materials, and the unstable solid electrolyte interphase. Various strategies, especially in terms of electrode design, have been proposed to address these issues. In this review, the recent progress on advanced anode materials of PIBs is systematically discussed, ranging from the design principles, and nanoscale fabrication and engineering to the structure-performance relationship. Finally, the remaining limitations, potential solutions, and possible research directions for the development of PIBs towards practical applications are presented. This review will provide new insights into the lab development and real-world applications of PIBs.
