Researchers create supercapacitors from waste PET plastic bottles that could power electric vehicles and electronics within 5 to 10 years.

Billions of cigarette butts end up on sidewalks, beaches, and gutters each year. They are small, easy to ignore, and hard to ...

Supercapacitors—also known as ultracapacitors—store energy similarly to batteries. However, they dispense power extremely quickly instead of over hours. As high-power-density energy storage systems, ...

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 ...

CAZENOVIA, N.Y., March 11, 2024 /PRNewswire/ -- Knowles Precision Devices, a segment of Knowles Corporation (KN), a leading global supplier of high performance components and solutions, today ...

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 ...

(Nanowerk Spotlight) As electronics become smaller, lighter, and more integrated into clothing, sensors, and mobile systems, the demand for energy storage devices that can operate under flexible, high ...

A recent article in Battery Energy outlines a method for converting cigarette filter waste (CFW) into carbon nanomaterials (CNMs) through a single-step, low-impact pyrolysis process. The goal is to ...

Transition metal dichalcogenides (TMDs) are only a few atoms thick two-dimensional (2D) nanomaterials composed of a transition metal like niobium, tungsten, molybdenum, and a chalcogen like tellurium, ...

Researchers have developed a low-cost device that can selectively capture carbon dioxide gas while it charges. Then, when it discharges, the CO2 can be released in a controlled way and collected to be ...
