文摘

Graphene-like 2D spinel MnCo2O4 powders have been synthesized by calcining a special metal-organic precursor. The initial discharge and charge capacities are 1157.3 mAhg−1 and 978.0 mAhg−1 at 0.2 Ag−1, respectively. The capacity retention ratio is about 80.0% after 100 cycles at 0.4 Ag−1. The 2D layered structure is retained perfectly after 200 cycles at 0.4 Ag−1.
