Surprising Discovery Could Lead to Better Batteries

by Brookhaven National Laboratory
Scientists have observed how lithium moves inside individual nanoparticles that make up batteries. The finding could help companies develop batteries that charge faster and last longer

Why Rechargeable Batteries Fail

by Marcia Goodrich-Michigan Technological University News Office
Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is essential to powering everything from cell phones to cordless power tools. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged, over and over again.

Scientists Spy on Lithium Ions

by Marcia Goodrich-Michigan Technological University News Office
July 5, 2013—Lithium ion batteries are at the energetic heart of almost all things tech, from cell phones to tablets to electric vehicles. That’s because they are a proven technology, light, long-lasting and powerful. But they aren’t perfect.
