About this Research Topic
The exhaustion of traditional energy sources and the deterioration of the environment are increasingly becoming serious issues, which makes the application of new energy technologies particularly urgent. Furthermore, the development of new low-cost and efficient energy storage devices has been rapidly growing to meet market demands for products such as hybrid electric vehicles and smart wearable devices. Supercapacitors, considered as one of the most promising candidates for the next generation of energy storage and conversion devices, have drawn a lot of attention due to their high power density, short charge/discharge time, and long cycling lifetime compared to other power source devices.
Improving the electrode materials used in a supercapacitor to increase their performance is an effective way of achieving high electronic transmission and high energy storage efficiency. Nanostructured materials can offer unique electrode properties, such as fast adsorption/desorption of ions, better redox activity, short electron/ion transport pathways, and better strain accommodation, thus significantly improving the rate capability of the whole electrode. Therefore, further study into the design and use of nanomaterials in supercapacitors is needed.
This Research Topic aims at collecting Original Research or Review articles on the development and application of nanomaterial supercapacitors. The Research Topic welcomes the following types of studies:
