A new battery technology could allow electric vehicles to drive for a million kilometres, according to the researchers who created it.
Alongside battery capacity, their lifespan remains one of the big drawbacks of electric vehicles. After some time, those battery degrade and need to be replaced – which can be costly, environmentally damaging and complicated.
Much of the problem comes from the way that lithium secondary batteries of the kind used in electric vehicles store their charge. They do so by converting electrical energy into chemical energy to store it, and then turn back into electrical energy to use it.
They do…
