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.

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.
