Ultrathin mesoporous ZnCo2O4 nanosheets as anode materials for high-performance lithium-ion batteries

Ultrathin ZnCo2O4 nanosheets with desired mesoporosity and high surface area are prepared by a facile hydrothermal approach. Such ZnCo2O4 nanostructures show excellent lithium storage performance as anode materials for LIBs. At a current density of 1 A g−1, the ultrathin ZnCo2O4 nanosheets present an initial specific capacity of 1251 mAh g−1 and the specific capacity remains at ∼810 mAh g−1 even after 200 discharge-charge cycles.290
