Lithium ion batteries explained (video)

I only watched the first 15 minutes so far. It is quite interesting for us geekier ones.

Jay Whitacre, a Carnegie Mellon professor with a joint appointment in Materials Science and Engineering and Public Policy, gives a quick overview of Lithium-ion batteries. Starting at the chemical level, he explains the properties and mechanics of the battery which give rise to macroscopic behavior, especially focusing on issues relevant to electric vehicles and other high-power systems. He then fields questions about the batteries themselves, ongoing research at Carnegie Mellon, and tricks for improving long-term performance, such as pulse-charging and pairing batteries with similar defects.
