A new battery design developed by researchers at the Massachusetts Institute of Technology could transform the way electric vehicles and the power grid store and discharge energy.
The MIT News Office reported that the new architecture suspends the active electrical components of a battery, such as positive and negative electrodes, as particles in a liquid. This black electric sludge, which resembles petroleum, has been dubbed "Cambridge crude" by its inventors.
The new design, called a "semi-solid flow cell," could allow electric vehicles to refuel by pumping the used electric sludge out and replacing it with fully charged electric sludge. Researchers say the new battery design should also make it possible to reduce the size and the cost of a complete battery system, making electric cars more competitive with contemporary gas-powered cars.
