Nanoparticle breakthrough could mean faster charging batteries

Researchers at Vanderbilt University have gained new insight into the nanoscale workings of Lithium Ion batteries, a discovery that could speed the development of batteries that can be recharged in seconds.The team of scientists spent the last 7 months investigating batteries containing quantum dots made of iron pyrite, also known as "fool's gold."Quantum dots are particles just a few tens of atoms wide, and researchers already know that their use in batteries allows for very fast charging.
