Rapid cellphone charging getting closer to reality

The ability to charge cellphones in seconds is one step closer after researchers at the University of Waterloo used nanotechnology to significantly improve energy-storage devices known as supercapacitors.

Measuring the heat capacity of condensed light

Liquid water is a very good heat storage medium – anyone with a Thermos bottle knows that. However, as soon as water boils or freezes, its storage capacity drops precipitously. Physicists at the University of Bonn have ...

New discovery for better batteries

Materials researchers at Uppsala University have made new discoveries in understanding energy storage in lithium-ion (Li-ion) batteries. This will help in the design of new materials for future batteries with significantly ...

Nano piano's lullaby could mean storage breakthrough

Researchers from the University of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational ...

Asian inventions dominate energy storage systems

In recent years, the number of patent applications for electrochemical energy storage technologies has soared. According to a study by the Technical University Munich, the largest volume of applications is submitted by developers ...

Chunky mobile devices? Soft graphene could help you downsize

Assuming you are geeky enough to open up any mobile device on the market – a phone, tablet or laptop – the most glaringly obvious component of the device is the battery: it generally consumes up to (if not more than) ...
