What is a dual-carbon electrochemical energy storage device?

Dual-carbon electrochemical energy storage device Apparently, although the types of anion and cation that can be used for energy storage on carbon-based electrodes are abundant, the energy storage mechanisms can be classified just into adsorption/desorption and intercalation/de-intercalation.

Are EDLCs a dual ion energy storage system?

Thus, EDLCs are typical “adsorption-adsorption” EES devices and are also a kind of dual-ion energy storage system, in which both anions and cations participate in the energy storage process.

Are generalized dual-carbon EES devices a green and efficient energy storage system?

In short, we believe that generalized dual-carbon EES devices with excellent charge storage performance and environmental/cost advantages are ideal green and efficient energy storage systems in the future.

What is ion storage in a dual-carbon device?

In all generalized dual-carbon devices, the essence of energy storage is the charge storage into the carbonaceous electrodes in form of ionic states. On carbonaceous electrodes, the ways of ion-storage mainly includes ion-adsorption and ion-intercalation.
