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 Hard carbons are promising anode materials for sodium‐ion batteries (SIBs), but they face challenges in balancing rate capability, specific capacity, and initial Coulombic efficiency (ICE). Direct pyrolysis of the precursor often fails to create a suitable structure storage.

However, creation these presents significant challenges. This work proposes zinc gluconate‐assisted catalytic carbonization strategy regulate numerous nanopores simultaneously. As temperature increases, trace amounts remain as single atoms featuring uniform coordination structure. mitigates risk electrochemically irreversible sites enhances transport rates. The resulting shows an excellent reversible 348.5 mAh g −1 at 30 mA high ICE 92.84%.
