A joint research effort has developed a high-performance self-charging energy storage device capable of efficiently storing ...

Battery technology is the talk of the town right now, as it’s the main bottleneck holding up progress on many facets of renewable energy. There are other technologies available for energy storage, ...

Before Lunar New Year, I had ordered two 3000 F, 2.7 V supercapacitors from China for about $4 each. I don’t actually remember why, but they arrived (unexpectedly) just before the holiday.

In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will ...

A polymer electrode developed by researchers at Queen Mary University of London and the University of Cambridge achieves energy storage close to the theoretical limit, but also demonstrates ...

Scientists at UCLA's California NanoSystems Institute have developed a new device that combines the high energy densities of batteries and the quick charge and discharge rates of supercapacitors. The ...

Supercapacitors can charge almost instantly, and discharge enormous amounts of power if needed. They could completely erase the Achilles heel of electric vehicles – their slow charging times – if they ...
