Scientists Create Smallest Battery Ever !!!

Scientists Create Smallest Battery Ever !!!

Posted by MydeaMedia

A team of researchers have produced world’s smallest battery, with anodes built from a single nanowire.
The smallest battery has been created by a group of researchers at the Sandia National Laboratories in Albuquerque led by Jianyu Huang and this discovery was reported in the December issue of the ‘Science’ journal.

The battery’s anode is a single nanowire, a mere one seven-thousandth of the thicknes of a human hair. The lithium-based battery was formed inside a transmission electron microscope, which uses electrons instead of light.
“This experiment enables us to study the charging and dicharging of a battery in real time and at atomic scale resolution, thus enlarging our understanding of the fundamental mechanisms by which batteries work,” said Jianyu Huang, leader of the team which worked on the project.
The battery consists of a single tin oxide nanowire anode 10 micrometers long and 100 nanometers in diameter, a bulk lithium cobalt oxide cathode 3 millimeters long, and an ionic liquid electrolyte.
The research claims the battery will help lead to better batteries in the future. The discovery could lead to improvements in laptop computers, cell phones and plug-in hybrid electric vehicles.
