Composite materials based on oxides of d and f elements and carbon layers

Nanocrystalline powder (~20 nm) with the composition of (ZrO 2 ) 0.6 (In2O3) 0.04 is synthesized on the basis of a co-precipitation method. After its consolidation, a dense and porous ceramic matrix for supercapacitor electrodes is obtained. The deposition conditions are determined for thin nanocarb...

Description
Summary:Nanocrystalline powder (~20 nm) with the composition of (ZrO 2 ) 0.6 (In2O3) 0.04 is synthesized on the basis of a co-precipitation method. After its consolidation, a dense and porous ceramic matrix for supercapacitor electrodes is obtained. The deposition conditions are determined for thin nanocarbon and MnO 2 , Co 3 O 4 layers on the porous ceramic or metal matrix. It is shown that the model supercapacitor with composite electrodes based on nickel foam and thin layers of nanocarbon and MnO 2 has the highest average specific capacitance.
