Drexel University researchers create innovative technique to study the exact electrochemical mechanisms occurring in batteries and supercapacitors. Using two scientific research procedures ...

A new and compact device configuration was created with two interpenetrated, individually addressable electrodes, allowing precise control over the geometric features and interactions between the ...

A new material called multiscale reduced graphene oxide could mean faster charging and power delivery than traditional ...

The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used ...

Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...
