Researchers at the Massachusetts Institute of Technology say a new battery design for electric vehicles could be a lightweight and inexpensive alternative. The goal for the team's three-year project, launched in September 2010, is to have a functioning prototype ready to be engineered as a replacement for existing electric-car batteries. At this point in the project, the prototype uses a “semi-solid flow” to separate the two functions of a battery--storing energy and discharging it when needed--into separate physical structures.
