How Electrodes Charge and Discharge

April 4, 2014 by Energy @ MIT

The electrochemical reactions inside the porous electrodes of batteries and fuel cells have been described by theorists, but never measured directly. Now, a team at MIT has figured out a way to measure the fundamental charge transfer rate — finding some significant surprises.[read more]

Will Batteries Be a Defining Technology Achievement in this Decade?

March 4, 2014 by Christine Hertzog

The 20th century was a time of extraordinary growth and change. In the first half of that century, relatively new technologies like electricity and telecommunications indelibly altered every aspect of life. In the latter half of the 20th century, computers radically reshaped work and play.[read more]
