Experts across the world believe that electric vehicles will sooner or later become the mainstream. They find it a more sustainable form of transport. But on what kind of batteries will these future electric vehicles run? Car makers are preferring the solid state-batteries over the older lithium-ion batteries. Let us find out the difference between them
For years now, electric vehicles have been powered by lithium-ion batteries. These batteries are similar to the ones used in your mobile phones, laptops and other consumer electronics. They use a liquid electrolyte, which makes them not only heavy, but also vulnerable to instability at high temperatures.
A lithium-ion battery uses liquid electrolyte solution, which makes it flammable and raises safety concerns. While a solid-state battery uses solid electrolyte. It has more energy density and is safer due to a lack of flammable liquid in it. Solid-state batteries could prove to be a game-changer for EVs and accelerate the shift away from fossil-fuel-powered personal vehicles.
Solid-state batteries are not a new technology. They have been in use for years in small devices such as smart watches and pacemakers. It is their use in a heavy-duty application like automobiles that is the new element here.
