MOF-derived porous Co3O4 cuboids with excellent performance as anode materials for lithium-ion batteries

Porous Co3O4 nanostructures with high capacities and energy density are extensively investigated as anode materials for lithium-ion batteries. Herein, we report a facile method to synthesis of porous Co3O4 cuboids through direct thermolysis of metal-organic frameworks (MOFs). Evaluated as anode materials for lithium-ion batteries, the resulted porous Co3O4 cuboids presented excellent cycling performance (886 mAh g(-1) at 100 mA g(-1) after 100 cycles) and good rate capability. The enhanced electrochemical performance can be attributed to their porous structures, which can shorten the pathway for lithium ions and electrons during cycling. (C) 2017 Published by Elsevier B.V.
