A MOF-derived method to construct well-arranged porous nanosheets for lithium ion batteries

Abstract

In this work, we report a facile route to fabricate a ZnCo₂O₄ nanosheet derived from metal–organic 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 g⁻¹ at a current density of 100 mA g⁻¹ after 50 cycles. More importantly, even at a current density of 1500 mA g⁻¹, the electrode material still exhibits a discharge capacity of 581.3 mA h g⁻¹ after 190 cycles. These results demonstrate that the ZnCo₂O₄ nanosheet shows great potential as an anode material for lithium ion batteries.
