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,

Fast-charging technology, which reduces charging time and enhances convenience, is attracting attention. Sodium-ion batteries (SIBs) potassium-ion (PIBs) are emerging as viable alternatives to lithium-ion (LIBs) due their abundant resources low cost. However, during fast discharging, the crystal structures of cathode materials in SIBs/PIBs can be damaged, negatively impacting performance, lifespan, capacity. To address this, there a need explore electrode with ultrahigh rate capabilities. Prussian Blue its analogues (PB PBAs) have shown great potential for both SIBs PIBs unique excellent electrochemical properties. This Review examines use PBAs PIBs, focusing on fast-charging (rate) performance commercialization potential. Through systematic analysis discussion, we hope provide practical guidance developing contributing advancement widespread adoption green energy technologies.

Abstract Single‐electron transfer, low alkali metal contents, and large‐molecular masses limit the capacity of cathodes. This study uses a cost‐effective light‐molecular‐mass orthosilicate material, K 2 FeSiO 4 , with high initial potassium content, as cathode for potassium‐ion batteries to enable transfer more than one electron. Despite limited valence change Fe ions during cycling, can undergo multiple electron transfers via successive oxygen anionic redox reactions generate reversible capacity. Although formation O‒O dimers in occur upon removing large amounts potassium, strong binding effect Si on O mitigates irreversible release voltage degradation cycling. achieves 236 mAh g −1 at 50 mA an energy density 520 Wh kg which be comparable commercial LiFePO materials. Moreover, it also exhibits 1400 stable cycles under high‐current conditions. These findings enhance potential commercialization prospects batteries.

Prussian blue analogs (PBAs), as a classical kind of microporous materials, have attracted substantial interests considering their well-defined framework structures, unique physicochemical properties and low cost. However, PBAs typically adopt cubic structure that features small pore size specific surface area, which greatly limits practical applications in various fields ranging from gas adsorption/separation to energy conversion/storage biomedical treatments. Here we report the facile general synthesis unconventional hexagonal open PBA structures. The obtained copper hexacyanocobaltate prisms (H-CuCo) demonstrate large area 12.32 Å 1273 m2 g−1, respectively, well exceeding those (5.48 443 g−1) traditional CuCo cubes (C-CuCo). Significantly, H-CuCo exhibits much superior uptake capacity over C-CuCo toward carbon dioxide hydrocarbon molecules. Mechanism studies reveal unsaturated Cu sites with planar quadrilateral configurations enhance adsorption performance. phase structure, size, high is synthesized, it delivers better molecular performance than counterpart.

The growing market for sodium-ion batteries has stimulated interest in research on Prussian blue-type cathode materials. Iron hexacyanoferrate (FeHCF) is considered a desirable cathode, but the incomplete electrochemical property of its low-spin iron sites hinders further practical application. In this paper, carboxymethyl cellulose demonstrated to have an appropriate binding energy through DFT calculations, synthesize blue situ, balance Fe3+ and water FeHCF, introduce FeIII vacancies activate Fe sites. Thus, at 1 C rate, it achieves initial discharge capacity 154.7 mAh g–1 with density 470.8 Wh kg–1. retention 70.2% after 4000 cycles rate 100 C. This work provides simpler way develop more cost-effective, faster, durable materials storage.
