Prussian Blue and Its Analogues for Commercializing Fast-Charging Sodium/Potassium-Ion Batteries

ACS Energy Letters, Год журнала: 2025, Номер unknown, С. 750 - 778

Опубликована: Янв. 13, 2025

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.

Priority Recovery of Lithium From Spent Lithium Iron Phosphate Batteries via H₂O‐Based Deep Eutectic Solvents

Carbon Neutralization, Год журнала: 2025, Номер 4(1)

Опубликована: Янв. 1, 2025

ABSTRACT The growing use of lithium iron phosphate (LFP) batteries has raised concerns about their environmental impact and recycling challenges, particularly the recovery Li. Here, we propose a new strategy for priority Li precise separation Fe P from spent LFP cathode materials via H 2 O‐based deep eutectic solvents (DESs). Through adjusting form metal complexes precipitation mode, above 99.95% can be dissolved in choline chloride‐anhydrous oxalic acid‐water (ChCl‐OA‐H O) DES, high efficiency 93.41% 97.40% accordingly are obtained. effects main parameters comprehensively investigated during leaching processes. mechanism pretreated is clarified rate‐controlling step heterogeneous dissolution reactions also identified. Results show that soluble phases 3 (PO 4 ) O formed after roasting pretreatment, Li(I) ions tend to C precipitates with 2− process so recovered preferentially purity 99.82%. After UV‐visible light irradiation, Fe(III) converted into Fe(II) ions, which react FeC by content, as Na PO ∙12H (99.98% purity). Additionally, plan used DES proposed performances still maintain stable three circles. method offers an approach simple process, efficiency, waste‐free DESs.
