7EX Technologies is a spin-off from Forschungszentrum Jülich developing modular electrochemical systems to extract lithium from aqueous sources such as geothermal brines, industrial process water, seawater, and recycling black mass. Its process uses an applied voltage to selectively deposit lithium into an electrode without membranes or added chemicals, and the organization says the system can work at very low concentrations. The company’s named founders and developers are Andreas Kuhlmann, Marten Huck, and Prof. Hans-Georg Steinrück; later JUICE contest coverage also names Max Meyer and Mohamed Elbashbishy as participants in the team. Public sources describe the intended market as battery and e-mobility supply chains, including direct extraction at geothermal or industrial sites, but do not identify specific customers. I found no verified public information in the provided sources about a funding round, amount, lead investor, or a confirmed headquarters city.
