Materials for Energy Storage and Conversion Based on Metal Oxides

Supercapacitors based on two dimensional VO 2 nanosheet electrodes in organic gel electrolyte

“…To increase the energy density of supercapacitors different nanostructured materials have been investigated including redox polymers and oxides. [13][14][15][16][17][18][19][20][21] Although, higher energy densities have been achieved with nanostructured materials, this has often been at the expense of modest power density and cycling stability. The approach to improving the energy storage performance of pseudocapacitors should aim at reducing the ion diffusion path length and increasing the electronic conductivity as well as the surface area of the active material.…”

One-step synthesis of crystalline Mn2O3 thin film by ultrasonic spray pyrolysis

“…[1][2][3][4] The incorporation of metal-oxides in these fields is ideal thanks to the development of metal oxide nanoscale structures. These structures enhance the material properties due to large surface area and well defined morphologies.…”

Two-dimensional heterostructures of V2O5 and reduced graphene oxide as electrodes for high energy density asymmetric supercapacitors

“…A vast variety of materials have been investigated as a cathode material for fabricating asymmetric supercapacitors, which include nanostructured carbonaceous materials, polymers, and transition metal oxides. [8][9][10][11][12][13][14][15][16][17][18] In particular, considerable research attention has been focused on metal oxides, 1,[19][20][21][22][23] due to ease of preparation with controllable nanostructured morphology and their fast reversible Faradaic reactions, which result in a relatively high energy density.…”
