How to Make Supercapacitors from Nanomaterials
Carol Stanier
Chinese and US scientists have made a supercapacitor with high power and energy density using nanocomposites containing carbon nanotubes.
High-performance electrical energy storage devices, such as supercapacitors, are essential for grid energy storage, electric vehicles, plug-in hybrid vehicles, power tools, mobile electronics, to name but a few.
A supercapacitor is essentially an electrochemical capacitor with high energy density. It generally consists of two conductors (cathode and anode),...
