Abstract

Hollow nanostructures have received broad attention for lithium-storage owing to their advantages in accommodating volume-change. However, taking the hollow sphere as an example, the void inside consumes a large volume fraction, resulting in a low material loading. Herein, we present a novel hollow nanosheet using Co₂SiO₄ as demonstrating example. The Co₂SiO₄ nanosheets-based anode exhibits a high and stable capacity of 1456 mAh g⁻¹ after 200 cycles at 0.2 A g⁻¹, and an excellent rate-performance after three rounds of cycling. In addition, the dynamic lithiation and delithiation of Co₂SiO₄ are presented using an in situ transmission electron microscopy technology.
