M.I.T. Researchers Develop Fast Lithium Ion Battery

Researchers at the Mssachusetts Institute of Technology (MIT) have developed a lithium ion battery with a unique surface structure that enables it to be fully-charged or discharged in 10 to 20 seconds compared to several minutes for a conventional battery. Furthermore, batteries with new surface structure do not degrade as much when repeatedly charged and recharged. This could lead to smaller, lighter and quickly-rechargable batteries for applications ranging from handheld electronics to electric cars.

The work, led by Gerbrand Ceder, the Richard P. Simmons Professor of Materials Science and Engineering, is reported in the March 12 issue of Nature.
