MIT scientists have developed new battery technology that lets you fill a battery with goo instead of throwing it away or recharging it when it’s drained.
The black goo, called Cambridge sludge, works just like a normal battery. The goo is a liquid suspension that has charged particles and flows like quicksand. There is a positive suspension on one side and a negative suspension on the other. A current is generated when the charge moves from one goo to another through a thin membrane.
