Scientists initially used metal oxides as asymmetric supercapacitor electrodes, but ... The researchers tested their supercapacitor devices and showed they could cycle 20,000 times and exhibited ...

and consequently cannot be applied to the fabrication of asymmetric nanoscale devices such as rectifiers and ambipolar devices that require the use of closely spaced dissimilar metal electrodes.

The research team has dramatically improved the performance of existing supercapacitor devices by utilizing transition metal-based electrode materials and proposed a new energy storage technology ...

Supercapacitors have an internal architecture that is more in line with basic capacitors. Both these devices store charge on metal plates or electrodes. However, unlike basic capacitors ...

Kaner tells us his team is now exploring using these electrodes to build hybrid supercapacitors on a large scale. You can see the device at work in the short video below. The research is described ...

The new electrode is designed to work with supercapacitors, which can charge and discharge ... graphene energy storages for wearables and various self solar energy-powered devices, which will have a ...

Thus, as Dr. Kondo has said, "the boron-doped nanodiamond electrodes are useful for aqueous supercapacitors, which function as high-energy storage devices suitable for high-speed charging and ...

A group of Drexel University researchers have created a fabric-like material electrode that could help make energy storage devices — batteries and supercapacitors — faster and less susceptible to ...

The electrodes are inexpensive and environmentally friendly to produce, say the researchers, and could someday be used to make supercapacitors to power a range of devices, from mobile phones to ...

This is thanks to a double layer that forms at the electrolyte–electrode interface of such devices when a voltage is applied. The conductive-wrapping technique can further increase the capacitance of ...
