Abstract

In-plane porous Co3O4 nanosheet assembled three-dimensional (3D) hierarchical clusters anchored on stainless steel mesh (Co3O4@SSM) were successfully fabricated using a hydrothermal method, followed by a low-temperature calcination process. The individual Co3O4 nanosheets are composed of numerous primary nanoparticles and secondary nanorods, and their thickness is correlated with the Co2+ concentration of the aqueous solution used for hydrothermal synthesis. The as-prepared materials were investigated as binder-free anodes for lithium ion batteries, and the results demonstrate a maximal specific capacity of up to 2030 mA h gāˆ’1 at a current density of 100 mA gāˆ’1, as well as superior cycling stability and rate capability due to the in-plane porous feature, optimized thickness and hierarchical assembly with abundant interstitial space of the nanosheets.
