The growing global energy demand necessitates the development of renewable solutions to mitigate greenhouse gas emissions and air pollution. To efficiently utilize yet intermittent sources such as solar wind power, there is a critical need for large-scale storage systems (EES) with high electrochemical performance. While lithium-ion batteries (LIBs) have been successfully used EES, surging price, coupled limited supply crucial metals like lithium cobalt, raised concerns about future sustainability. In this context, potassium-ion (PIBs) emerged promising alternatives commercial LIBs. Leveraging low cost potassium resources, abundant natural reserves, similar chemical properties potassium, PIBs exhibit excellent ion transport kinetics in electrolytes. This review starts from fundamental principles structural regulation PIBs, offering comprehensive overview their current research status. It covers cathode materials, anode electrolytes, binders, separators, combining insights full battery performance, degradation mechanisms,

Abstract Metal sulfides have shown great promise for sodium‐ion batteries due to their excellent redox reversibility and relatively high capacity. However, metal generally suffer from sluggish charge transport serious volume change during the charge–discharge process. Herein, potato chip‐like nitrogen‐doped carbon‐coated ZnS/Sb 2 S 3 heterojunction (ZnS/Sb @NC) is precisely synthesized through a sulfurization reaction, subsequent cation exchange process between Zn 2+ Sb 3+ . The theoretical calculations experimental studies reveal boosted transfer in @NC composites. Therefore, electrode exhibits cycling stability (a reversible capacity of 511.4 mAh g ‐1 after 450 cycles) superior rate performance (400.4 at 10 A ). In addition, based on conversion‐alloy reaction mechanism store Na + , which disclosed by X‐ray diffraction resolution transmission electron microscopy analysis. This effective synthesis method can provide reference design other high‐performance materials batteries.
