Sentences with phrase «high conductivity electrodes»

Not exact matches

These electrodes must have a high surface area per unit weight, high electrical conductivity and capacitance and be physically robust so they do not degrade during operation in liquid or hostile environments.

Metal nitrides such as titanium nitride, which offer both high conductivity and capacitance, are a promising alternative, but they tend to oxidize in watery environments that limits their lifetime as an electrode.

Scientists initially used metal oxides as asymmetric supercapacitor electrodes, but, as metal oxides do not have particularly high electrical conductivities and become unstable over long operating cycles, it was clear that a better alternative was needed.

High electrical conductivity and large accessible surface area, which are required for ideal electrode materials in energy devices, are opposed to each other in current materials.

Wachsman and his research colleagues have also published details in Science on a potential path toward SOFCs that operate at temperatures as low as 350 degrees C with a new design that features high - conductivity electrolytes and a specially nanostructured electrode.

In numerous tests, the researcher and his team investigated the nano - material graphene, whose extremely high specific surface area of up to 2,600 m2 / g and high electrical conductivity practically cries out for use as an electrode material.
