New microbatteries a boost for electronics

Liz Ahlberg, Physical Sciences Editor: CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most
powerful batteries on the planet are only a few millimeters in size, yet
they pack such a punch that a driver could use a cellphone powered by
these batteries to jump-start a dead car battery – and then recharge
the phone in the blink of an eye.
Developed by researchers at the University of Illinois at
Urbana-Champaign, the new microbatteries out-power even the best
supercapacitors and could drive new applications in radio communications
and compact electronics.
Led by William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.
“This is a whole new way to think about batteries,” King said. “A battery can deliver far more power than anybody ever thought. In recent decades, electronics have gotten small. The thinking parts of computers have gotten small. And the battery has lagged far behind. This is a microtechnology that could change all of that. Now the power source is as high-performance as the rest of it.”...
