| The next generation of lithium-ion batteries could be small enough to pour out of a saltshaker. |
Lithium-ion batteries have become ubiquitous in today's consumer electronics, powering laptops, cell phones, and portable music players. Now research funded by the Department of Defense's research wing, DARPA, is pushing the limits of this technology in trying to create some of the tiniest batteries on Earth, the largest of which would be no bigger than a grain of sand.
These tiny energy storage devices could one day be used to power the electronics and mechanical components of tiny micro- to nanoscale devices. TECHNEWS DAILY
