Ionic-liquid assisted architecture of amorphous nanoporous zinc-rich carbon-based microstars for lithium storage

Abstract

Amorphous Zn-rich nitrogen-doped carbon-based microstars are synthesized using an ionic liquid-assisted method and annealing process. The microstars exhibit a high reversible capacity of 756 mA h g⁻¹ and a capacity retention of 98% after 120 cycles at 0.5 A g⁻¹ due to their large surface area, hierarchical nanopores, and uniform distribution of zinc and nitrogen.
