Battery company theion has the solution for ultra-fast charging and safe battery anodes – validated by an independent institute. One of the biggest challenges in batteries with lithium metal foils as anodes is the formation of dendrites during rapid charging and discharging. This ultimately represents a safety risk. As part of its development of lithium-sulfur batteries, the Berlin battery company theion has developed a polymer structure with special coatings as a replacement for current anode materials such as graphite, silicon or lithium metal and has successfully manufactured more than 2,000 charging devices. and discharge cycles achieved. This has been confirmed by a leading independent research institute in Germany. The development of a long-lasting, lightweight anode is one of the most important requirements for lithium-sulfur batteries. These offer three times the energy density at only a third of the cost compared to today’s conventional lithium-ion batteries Dr. Ulrich Ehmes , CEO of theion, said: Our new anode design is an important milestone for theion – and therefore for the entire industry. “With our anode structure, which has been optimized and tested over several thousand cycles, we have solved the dendrite and fast charging problem of lithium Metal foils successfully solved. This is a key component for our high-performance lithium-sulfur cell. Marek Slavik, co-founder of theion, said: Our breakthrough in lightweight and fast-charging battery chemistry makes lithium-sulfur batteries ideal for electric propulsion in aviation, such as eVTOLs and traditional propeller aircraft. “The fundamental difference between sulfur and existing LFP -, NMC or other transfer metal based cathodes is that sulfur as a multi-stage redox conversion cathode is able to mobilize 16 electrons, while, for example, an LFP cathode can only mobilize one electron the energy density of 16 electrons compared to one electron that turns the wheels of an electric car or drives the propellers of an electric plane.” theion is backed by Team Global, a holding group that invests in cutting-edge technology companies. With an exceptional track record and significant investments in eVTOL companies, theion’s place in this portfolio is extremely synergistic. In addition, theion has attracted great interest from leading companies in the aviation industry to support them on their journey to electric flight.
