Recharging your electric car could be as quick and easy as a stop at the filling station. Pumping electric power. Today, on Engineering Works!
One of the problems with electric cars seems is what you have to do to recharge the batteries. You’ve got to stop, park the car and plug it in. That takes time, time you probably don’t have if you’re on a trip somewhere.
Engineers at MIT have come up with an idea that’ll let you recharge your electric car almost the same way you fill up your gas-powered car.
At the pump.
The heart of the new technology is a new kind of battery, called a semi-solid flow cell. In this version of a battery, the battery’s negative and positive electrodes aren’t metal rods. They’re tiny solid particles floating in a thick goo. The battery separates the two kinds of particles with a filter.
This puts the battery’s energy storage and energy discharge functions into two separate places. This is can mean more efficient batteries. And more efficient means batteries that are smaller and cheaper than today’s batteries.
And even cooler, the goo should make it possible to pump out the part of the battery that’s used up its electric charge and pump in fresh goo with a full charge of electricity. Almost like filling up with gas. And the goo could be recharged just like a normal battery.
Our batteries need recharging, so we’re done for now. See you next time.
