Abstract

In this work, we report a facile route to fabricate a ZnCo2O4 nanosheet derived from metalorganic frameworks. The as-prepared ZnCo2O4 nanosheet material for lithium-ion batteries shows an excellent electrochemical performance. The obtained ZnCo2O4 nanosheet delivers a high reversible capacity of 1640.8 mA h g1 at a current density of 100 mA g1 after 50 cycles. More importantly, even at a current density of 1500 mA g1, the electrode material still exhibits a discharge capacity of 581.3 mA h g1 after 190 cycles. These results demonstrate that the ZnCo2O4 nanosheet shows great potential as an anode material for lithium ion batteries.
