Low-carbon Supercapacitors: Towards Sustainability in Energy Storage Devices

Supercapacitors can both hold large amounts of energy and charge up almost instantly. They have higher energy densities, higher efficiencies and longer lifetimes so can be used in a wide range of energy harvesting and storage systems including portable power and grid applications.

Despite offering key performance advantages, many device components pose significant environmental hazards, often containing fluorine, sulfur and cyanide groups which are harmful when discarded. In recent years, t...
