Believe it or not, Theion, a battery startup based in Germany, has claimed that a new sulfur battery technology could help electric cars provide 900 miles (1448.41 kms) of driving range on a single charge, a report in Frobes.com said.
Even more interesting thing here is the fact that sulfur is cheap as compared to the core ingredients of conventional NMC li-ion batteries.
Why EV batteries are expensive?
What makes the batteries that are currently used in electric cars expensive are the chock-full of rare earth minerals. Moreover, it’s a daunting task to produce them.
Theion is claiming that it can develop a battery that can make it all hassle-free by using the technology based on minerals that are abundant as compared to those used in ‘conventional’ lithium ion cells.
Sulfur battery technology
The key to this technology is sulfur, which doesn’t require much energy to produce as compared to nickel or manganese or cobalt and is comparatively cheaper as well, as per the company.
“Existing battery technology uses nickel, manganese, and cobalt for the cathode,” says Theion CEO Dr Ulrich Ehmes.
“It’s called NMC 811, because it has 80% nickel, 10% cobalt, 10% manganese. In our case, we replace this NMC 811 with sulfur. So we have no nickel, no manganese, no cobalt, and we replace the current collective folds of copper and aluminum with graphene, so we have also no aluminum and no copper in our cells either. The only things we have in our cells are lithium metal foil, sulfur, and carbon.”
The company also has plans to ship its material to aerospace customers as part of the qualification stage this year itself. It says it will then provide services to drones, mobile phones, laptops and air taxis before entering the electric vehicle sectors by 2024.
