Good news, but the article is based on a company news release. Potentially a game changer. These lithium-sulfur batteries seem to have a lot of advantages.
"In a potentially game-changing move for the EV industry, Stellantis and Zeta Energy Corp have teamed up to develop the next-generation EV battery with more range, more power, 50% faster charging, and at less than half the cost. ...
A Li-ion battery typically packs between 150-250 watt-hours per kilogram (Wh/kg) of energy in them. Li-S can achieve up to 400-600 Wh/kg. ...
Li-S can provide same amount of power with a smaller package – meaning not only greater range in your EV because the batteries are going to weigh 30-50% less, but better handling and performance. ...
The two companies also claim improvements in fast-charging speeds by as much as 50% over traditional lithium-ion battery packs. Li-S has a simpler chemistry and doesn't rely on the slow diffusion of lithium ions into solid materials (like the graphite in Li-ion). Instead, reactions occur directly between the lithium and sulfur which is faster and more straightforward. They also operate at lower voltages, so they don't have as much resistance during charging, making them absorb energy more quickly.
The kicker: Li-S batteries are expected to cost less than half the price per kilowatt-hour than Li-ion. ...
They also ditch expensive, hard-to-source materials like cobalt, graphite, manganese or nickel; which Li-ion is also made from. ...
The sulfur in Li-S is in a solid state. Li-S batteries don't have flammable electrolytes like what you'd find in a typical Li-ion battery. ..."
