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.

Superstretchable, supercompressible supercapacitors

Flexible, wearable electronics require equally flexible, wearable power sources. In the journal Angewandte Chemie, Chinese scientists have introduced an extraordinarily stretchable and compressible polyelectrolyte which, ...
