Abstract

We report a yolk-shelled anode material with an MoS₂/C core, large inner void and C@MoS₂ shell (MoS₂/C@Void@C@MoS₂). This design could accelerate Na⁺/K⁺ reaction kinetics and endure volume changes. Based on the kinetics analysis and calculations based on density functional theory, this structure could effectively enhance the high-rate sodium/potassium storage capability.
