A team of researchers has developed an interesting optical method to study the formation of the electrical double layer (EDL) ...

Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions ...

The capacitor uses layers of flexible, three-dimensional porous foam formed from graphene and silver. It is an EDLC (electrochemical double layer capacitor) type supercapacitor, built from a stack of ...

A supercapacitor differs from an ordinary capacitor in two important ways ... polarized electrode, (4) Helmholtz double layer, (5) electrolyte having positive and negative ions, (6) separator. (Image: ...
