Enhancing the Electrochemical Performance of Aqueous Zinc-Ion Batteries Using 1,4-Diazabicyclo[2.2.2] Octane-Intercalated Vanadium Pentoxide Cathode

The Journal of Physical Chemistry C, Journal Year: 2024, Volume and Issue: 128(35), P. 14594 - 14603

Published: Aug. 22, 2024

Vanadium-based cathodes are promising materials for aqueous zinc-ion batteries owing to their high capacity; however, layered structure tends collapse, adversely affecting the electrochemical properties and cycling stability. Guest preintercalation has emerged as an effective approach enhancing behavior of vanadium-based cathodes. Herein, we investigate effect introducing small molecule 1,4-diazabicyclo[2.2.2] octane (C6H12N2) into interlayer space vanadium oxide on its performance. Using distinct synthesis methods, obtain oxides (DVO) in either molecular (MDVO) or ionic (IDVO) intercalated forms. Extensive characterizations investigations reveal that IDVO possesses a stabilized but suffers from low capacity, potentially due strong bonds between layers hindering transport Zn2+/H+. Conversely, MDVO exhibits larger spacing weaker interactions, providing more storage Zn2+/H+ enhanced capacity. Furthermore, energy mechanism is discussed. This strategy offers valuable insights future research.
