Sticky composites

New battery technology employs multifunctional materials

Lithium-ion batteries power a vast array of modern devices, from cell phones, laptops, and laser pointers to thermometers, hearing aids, and pacemakers. The electrodes in these batteries typically comprise three components: active materials, conductive additives, and binders.

Now, a team of researchers at the University of Delaware has discovered a “sticky” conductive material that may eliminate the need for binders.  (more…)

Stretchable energy sources

UD researchers develop stretchable wire-shaped supercapacitor

Advances in flexible and stretchable electronics have prompted researchers to explore ways to create stretchable supercapacitors — robust energy storage devices — to power these and other devices. 

Supercapacitors offer significant advantages over common batteries, including the ability to recharge in seconds, exceptionally long life span and high reliability, leading to their incorporation in portable consumer electronics, memory backup devices, hybrid vehicles and even large industrial scale power and energy management systems.
