(a) Discharge and charge profiles of mesoporous Co3O4 nanoplates at 1 C current rate. (b) Cycling performance of mesoporous Co3O4 nanoplates at 1 C current rate. (c) Discharge capacity vs. cycle number of mesoporous Co3O4 nanoplates at 10 C current rate. (d) The rate performance of mesoporous Co3O4 crystals at varied current rates. The insets of (b) and (c) show the corresponding Coulombic efficiency.
