Summary: Shortages in lithium supply have led to the exploration of alternatives for widespread grid system applications, and potassium-ion batteries (PIBs) have emerged as promising candidates. However, the large radius of K+ ions has hindered the development of satisfactory cathode materials. In this study, a layered K0.37MnO2•0.25H(2)O (KMO) cathode was synthesized using solid-phase synthesis, which showed potential for accommodating the migration and transport of K+ ions. The KMO cathode material exhibited high initial specific capacities at different current densities, and the storage mechanism of K+ ions in PIBs was investigated. Overall, the proposed KMO cathode material was confirmed to be auspicious for potential use in PIBs.

Summary: Layered double hydroxides (LDHs) are investigated as anode materials for potassium ion batteries (PIBs), with MgFe-LDH showing higher K+ storage capacity but lower initial Coulombic efficiency compared to MgAl-LDH. The dominant mechanisms for K+ storage in these materials are electrical double layer effect and a faradaic process involving a conversion reaction between Fe3+ and Fe2+. The study suggests the potential of developing LDHs as efficient anode materials for PIBs.

Summary: Potassium ion batteries (PIBs) are attractive due to abundant potassium resources, low cost, and high potential. However, the larger radius of K+ compared to Na+/Li+, poor kinetics, and unstable structure result in inferior electrochemical performance. In this study, a 3D fluorine-doped carbon@Ti3C2 MXene (3D FC@Ti3C2) composite is proposed as an anode material for PIBs. The composite exhibits enhanced electrochemical properties, including high capacity and cyclic stability, attributed to the protective carbon coating, fluorine-doped carbon with more defects and active sites, enlarged interlayer spacing, and the 3D interconnected carbon framework.

Summary: Layered oxides have been investigated as electrode materials for Na-ion battery due to their abundant species and easy preparation. However, most of the layered oxides are sensitive to water and cannot be used in aqueous Na-ion batteries. This study proposes doping Ti4+ ions in the vacancies of layered Na-2[Mn(3)Vac(0.1)Ti(0.4)]O-7 to change the local crystal structure, resulting in enhanced rate capability and cycling stability. The improved performance is attributed to the enhanced kinetics of electron and Na+ ion transportation. Additionally, this research successfully fabricates an aqueous Na-ion cell using layered Na-2[Mn(3)Vac(0.1)Ti(0.4)]O-7 as an anode, demonstrating excellent rate and cycle performance.

Summary: Due to its abundant precursors, simple preparation, and environmental friendliness, nitrogen-doped carbon is regarded as a promising anode material for potassium-ion batteries (PIBs). In this study, nitrogen-doped carbon material (NC-2) was synthesized using exfoliated g-C3N4 as a precursor, combined with sucrose, and subjected to hydrothermal and high-temperature pyrolysis. NC-2 exhibited a high nitrogen content, porous layered structure, and large interlayer spacing. As the anode for PIBs, NC-2 demonstrated a high reversible capacity of 261.07 mAh g-1 at 0.1 A g-1 and an impressive rate performance of 153.36 mAh g-1 at 2 A g-1. The excellent performance of NC-2 can be attributed to its porous layered structure, enlarged interlayer spacing promoting ion diffusion, and the presence of abundant active sites due to nitrogen doping. These results indicate the great potential of NC-2 as a PIBs anode material.
