Key Points

Interfacial charge redistribution elevates oxidation states of Ti and Co, enhancing performance.
Cycling-induced evolution leads to the formation of Co/CoO nanoparticles, ensuring long-term stability.
Core-shell materials were developed to lower the ion migration barrier for improved efficiency in energy storage.
Findings highlight the significance of nanoscale interfaces in advancing lithium-ion transport and battery longevity.

Implication

Analysis of nanoscale interfaces improves lithium-ion transport in Co3O4 anodes, indicating their potential for stability.

Abstract

Cycling-induced evolution of the Co 3 O 4 shell into dispersed Co/CoO nanoparticles ensures long-term stability. Meanwhile, interfacial charge redistribution elevates the oxidation states of Ti and Co and lowers the ion migration barrier.
