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, ...

Supercapacitors have long promised electric vehicles that refill in minutes, grids that shrug off sudden surges, and gadgets that never seem to wear out, but their limited energy storage has kept them ...

Engineers have achieved a breakthrough that could redefine the future of energy storage. Scientists at Monash University have developed a novel carbon-based material for supercapacitors that combines ...

Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported the first example of ultrafast 3D-printed graphene supercapacitor electrodes that outperform comparable ...

Graphene capacitors are both highly flexible and have an energy density far beyond existing electrochemical capacitors, possibly within reach of conventional lithium-ion and nickel metal hydride ...

While graphene has long been heralded as the future of supercapacitors, new research indicates that fibers from hemp plants can contain as much energy and power as graphene itself. What’s more, its ...

(Nanowerk Spotlight) The proliferation of wearable devices—from smart watches to AR glasses—necessitates ever-smaller on-board energy solutions that can deliver bursts of power while remaining ...

Scientists have set themselves the goal of improving these ubiquitous, fast storage devices by developing a new kind of electrode based on graphene. Supercapacitors are the nimble little siblings of ...

Prof. WANG Zhenyang's research group from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) has enhanced the energy storage capacity of graphene supercapacitors ...

Researchers from Texas A&M University have shown that a supercapacitor responds to charging by stretching and expanding, storing energy. This discovery can be applied to the construction of novel ...
