Figure 5

Supercapacitor performance of CoO@Ni2P series materials with different average molecular weights of PVP and phosphating temperatures in a three-electrode system: (a) CV curves of NP-10k-T3 at different scan rates. (b) The areal capacitance contrast calculated from corresponding CV curves. (c) Galvanostatic discharge curves of NP-10k-T3 at different current rates. (d) The areal capacitance contrast calculated from corresponding galvanostatic discharge curves. (e, f) Long-term charge-discharge performance contrast at a current rate of 50 mA cm-2.
