Batteries charge quickly and retain capacity, thanks to new structure
CHAMPAIGN, Ill. — The batteries in Illinois professor Paul Braun's lab look like any others, but they pack a surprise inside.
Braun's group developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity. The researchers' findings will be published in the March 20 advance online edition of the journal Nature Nanotechnology.
Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for ...
