Abstract Potassium‐ion batteries (PIBs) using carbonaceous anode materials have attracted a great deal of research interest. However, the large atomic size potassium ions inevitably leads to huge volume expansion and collapse anodes during intercalation, which greatly hinders rate performance cycling life. In this work, carbon nanotube‐derived porous N‐doped nanoribbon (CNR) bundles are designed as an for PIBs. These CNR in rich defects provide fast channels charge transport abundant active sites ion storage.

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 Binary metal sulfides hold significant promise as anode materials for advanced sodium‐ion batteries (SIBs), but their application is often limited by rapid capacity degradation and slow reaction kinetics. While carbon composites are frequently used to address these issues, the influence of sequence carbonization sulfidation on performance has been largely overlooked. To bridge this gap, Co‐Sn synthesized through various processes examine impact synthesis methods material properties. Among these, one‐step CSS‐C1 exhibits enhanced kinetics excellent stability. It delivers a 220.4 mAh g −1 at an ultra‐high current density 20 A maintained 389 over 2300 cycles 10 . When assembled into full‐cell devices (CSS‐C1||Na 3 V 2 (PO 4 ) ), it demonstrates stable retention 900 cycles, establishing highly efficient SIBs.
