Figure 7

Cyclic voltammograms of coronal hybrids in a 3 M KOH solution using a three-electrode configuration at various scan rates for (a) Co-Mn LDH@3D-PG hybrids, (b) Ni-Mn LDH@3D-PG hybrids, and (c) Ni-Co LDH@3D-PG hybrids. GCD profiles obtained at various current densities for (d) Co-Mn LDH@3D-PG hybrids, (e) Ni-Mn LDH@3D-PG hybrids, and (f) Ni-Co LDH@3D-PG hybrids. Specific capacity vs. current density profiles obtained at various current densities for (g) Co-Mn LDH@3D-PG hybrids, (h) Ni-Mn LDH@3D-PG hybrids, and (i) Ni-Co LDH@3D-PG hybrids.
