Supercapacitors, with the merits of both capacitors for safe and fast charge and batteries for high energy storage have drawn tremendous attention. Recently, laser scribed graphene has been increasingly studied for super...

In this work, the Perovskite powders LaFe0.5Cr0.5O3 with a space group of P m - 3 m was obtained by the sol-gel method. The nanoscale powders of LaFe0.5Cr0.5O3 have been tested as a cathode material for electrochemical s...

Perovskite bimetallic oxides as electrode material blends can be an appropriate method to enhance the supercapacitor properties. In the present research, SrO 0.5 :MnO 0.5 nanostructures (NS) were synthesized by a facile ...

The nanocrystalline NiMoO4 obtained as a result of hydrothermal synthesis was exposed to laser radiation with a pulse energy of 70 mJ/cm2 for 5 minutes. The phase composition and size of crystallites of the triclinic str...

Nickel molybdate due to its electronic configuration, stable crystalline framework, oxidation-reduction behavior displays perfect physical and chemical properties and rather high electrical conductivity that altogether l...

Supercapacitors, also called ultracapacitors or electrochemical capacitors, store electrical charge on high-surface-area conducting materials. Their widespread use is limited by their low energy storage density and relat...

Electrochemical energy conversion devices are pervasive in our daily lives. Batteries, fuel cells and supercapacitors belong to the same family of energy conversion devices. They are all based on the fundamentals of elec...
