Nickel-Iron Battery used by Thomson Edison gets a new lifeJune 29, 2012 by: Rituraj Mishra
Before lithium-ion batteries became the most powerful thing in our lives, Thomson Edison used the nickel-iron batteries to power his EVs way back in the 19th century. People at Stanford University are trying to revive the old technology.
The reason nickel-iron batteries were done away with is because they took too much time to charge and discharge and hence were never on demand with the power.
But now the scientists say they have solved the problem of slow charge and discharge, increasing both of them by 100 times at least. Use of very futuristic technology like graphene and carbon nanotubes can be attributed for the same.
The research of the college aims at powering the car’s auxiliary systems and then store energy regenerated by braking.
