Can you make a supercapacitor from kapton tape? Yep! Using a laser, we can decompose the Kapton (polyimide) into a graphene ...

This new model accounts for a wide range of ion-electrode interactions and predicts a device's ability to store electric charge. The model's theoretical predictions align with the experimental results ...

Scientists in the U.S. claim to have successfully upcycled PET waste bottles into an electrochemical active-carbon material that functions as a double‐layer supercapacitor substance. They said that ...

Supercapacitors, sometimes referred to as electric double-layer capacitors (EDLCs) or ultracapacitors, are cutting-edge energy storage devices with special qualities. Supercapacitors, in contrast to ...

Consider an electric vehicle that takes only a few seconds to recharge while braking and then using that energy to power up the vehicle until the next stop. Imagine a lightweight smartphone that, ...

This article reports on work where as-synthesized BCNTs are prepared by catalytic thermal Chemical Vapor Deposition (CVD) resulting in fast charge transfer between electrode and electrolyte. The ...
