Battery researchers are seeking options with better performance, improved environmental sustainability and lower cost than lithium-ion batteries.

HS Hyosung has announced a joint venture with Umicore to manufacture silicon anode materials, aimed at advancing battery technology and boosting domestic jobs.

The F-axial coordinated Sb SAs (F-Sb SAs) can effectively reduce the desolvation energy of hydrated Zn 2+ ions and greatly accelerate the migration kinetics of Zn 2+ ions. The symmetric cell and Zn-I 2 batteries based on F-Sb SAs@Zn anode exhibit outstanding stability. Abstract Aqueous zinc-ion batteries have emerged as promising candidates for next-generation energy storage due to their superior safety and lower cost. However, the sluggish desolvation kinetics of hydrated zinc ions at anode causes critical issues, including dendritic growth, hydrogen evolution reaction (HER), and anode corrosion. Herein, taking Sb single-atoms (SAs) as a proof-of-concept, a F-axial coordination engineering strategy is proposed to accelerate the desolvation kinetics and thus ensure robust cycling stability of Zn anode. Theoretical calculations reveal that the electron delocalization triggered by F-axial coordination and p-p orbital hybridization between Sb and F atoms strengthens the affinity for Zn. Electrochemical analysis and in situ/ex situ spectroscopy characterizations demonstrate that the introduction of F-axial coordination can effectively reduce the energy barrier for the desolvation process of hydrated zinc ions, inhibit HER, uniform Zn 2+ diffusion, and enable lateral Zn deposition. Consequently, the symmetric zinc battery based on F-axial coordinated Sb SAs (F-Sb SAs)-modified Zn anode features unprecedented stability up to 6000 and 1200 h at 5 and 20 mA cm −2 , respectively. Furthermore, the fabricated F-Sb SAs@Zn||I 2 battery exhibits remarkably long durability at a high current density of 10 A g −1 , maintaining 94.3% of capacity even after 100 000 cycles.
