A Berlin-based startup with ambitious plans to transform battery technology has secured significant funding to advance its innovative sulfur-based batteries. According to information first reported by Tagesspiegel, Theion has raised €15 million ($16.4 million) in Series A funding to develop what could be a game-changer for electric mobility worldwide.
The investment round was led by German-American holding company Team Global, German renewables firm Enpal, and the Geschwister Oetker Beteiligungen group, which manages 146 subsidiaries of the billion-euro food conglomerate.
Theion, headquartered in Berlin-Adlershof Technology Park, claims its crystal sulfur battery technology weighs only one-third as much as conventional lithium-ion batteries while costing just a third of the price. The technology replaces metals like nickel and cobalt with sulfur, an abundant element that is often a byproduct of industrial processes.
The company's battery roadmap aims to achieve 1,000 Wh/kg energy density – triple that of current batteries – with 1,000 charging cycles. Theion also highlights that their batteries can be charged within minutes and are inherently safer than conventional options.
What makes this technology particularly attractive is its sustainability profile. The production requires no harmful mining, uses no solvents, and consumes just one-third of the energy across the value chain compared to state-of-the-art batteries.
Theion, which employs about 20 scientists, expects global battery demand to triple by 2030, reaching an estimated market volume of €500 billion annually. If successful in commercializing their technology, Theion could significantly accelerate the transition away from fossil fuels in vehicles, solar energy storage systems, and even aircraft.
