BERLIN, Germany – German battery startup Theion is promising a new sulfur battery technology that could help mainstream electric cars offer 900 miles of range on a single charge. The best part? Compared to the core ingredients of conventional NMC li-ion batteries, sulfur is cheap.
Electric cars batteries are chock-full of rare earth minerals. That makes them expensive, and — with rare exceptions — ethically problematic to produce. German company Theion is betting that it can build a competitive battery that can sidestep all of that, by basing its battery technology on minerals that are far more abundant than those used in “conventional” lithium-ion cells.
Scratch that. Not only competitive — but much, much better.
The key to Theion’s technology is sulfur. Compared to nickel or manganese or cobalt, sulphur requires much less energy to produce and costs just pennies on the dollar to source, according to the company.
