Is cobalt molybdate a good electrode material for supercapacitors?

Cobalt molybdate (CoMoO 4) nanomaterials have been regarded as one of the most prospective electrode materials for supercapacitors due to their high theoretical capacitance and excellent electrical conductivity.

What is cobalt molybdate (CoMoO4)?

Recently, cobalt molybdate (CoMoO4) is attracting ever-growing interest for electrochemical energy storage because of its high theoretical capacity, natural abundance, and environmental friendliness .

Why are cobalt molybdate materials reversible redox reactions?

Cobalt molybdate materials, a kind of two-element transitional metal oxide, facilitate reversible redox reactions due to their abundant reserves and variable valence states of cobalt and molybdenum ions, and their electrochemical performance is usually better than that of single-component oxides.

What is the power density of a supercapacitor?

An asymmetric supercapacitor assembled with the optimized P-CoMoO 4-x as positive electrode and activated carbon as negative electrode delivers a high energy density of 58 W h kg−1 at a power density of 850 W kg −1 as well as achieves excellent cycling lifespan.

What is the capacitance of a bismuth molybdate electrode?

The GCD measurements (Fig. 25(c)) of the bismuth molybdate electrode were examined at various applied current densities of 1–5 Ag−1, and the results showed that the specific capacitances were 182, 152, 156, 149, and 146 Fg −1 respectively.

Which nanorods are suitable for a hybrid supercapacitor?

The Ni (1-α) Co (α) MoO 4 nanorods with (α = 0, 0.1, 0.3, and 0.5 M) were made using a hydrothermal technique and were found to be excellent electrode materials in a hybrid supercapacitor (Fig. 13 (b)) .
