theion, a Berlin-based battery firm, has announced a game-changing advancement in battery technology with its novel anode chemistry.
A major issue with batteries that include lithium metal foils on the anode is that dendrites form during rapid charging and discharging, which can indulge safety risk.
theion has created a lightweight polymer host with unique coatings to replace cutting-edge anode chemistries like graphite, silicon-rich graphite, or lithium metal foils in keeping with its research on lithium-sulphur batteries.
This technology has been successfully tested for over 2,000 charging and discharging cycles. A prestigious independent research center in Germany has confirmed this, finding that the anode in a symmetrical cell cycles steadily affirmed the official release.
One of the main obstacles to the development of lithium-sulphur batteries—which provide three times the energy density of current ordinary lithium-Ion batteries at a third of the price and use a lot less energy to produce—is overcoming the difficulty of creating a long-lasting, light anode.
“Our new anode design is an important milestone,” said Dr. Ulrich Ehmes CEO of theion; “With our host anode chemistry optimised and tested over several thousand cycles, we have solved the dendrite and fast charging problem of lithium metal foils. This is a key component for our high-performance lithium-sulphur cell”.
“Our breakthrough in lightweight and fast-charging battery chemistry makes lithium-sulphur batteries ideal for electric powertrains in aviation, such as eVTOLs and traditional prop-driven aircraft” said Marek Slavik, theion co-founder, “the fundamental difference between sulphur and existing LFP, NMC or other transition metal based cathodes is, that sulphur, as a multistep redox conversion cathode, is able to realise 16 electrons compared to, as an example, an insertion type LFP cathode, which can realise just one electron. Ultimately, it’s the energy density of 16 versus one electron that will spin the wheels on your electric car or turn the fans or props on an electric aircraft.”
Team Global, a holding group that makes investments in cutting-edge technological companies, supports theion. With a proven track record of performance and large investments in eVTOL businesses, theion has a very complementary position in the portfolio.
Leading aviation companies have also expressed a great deal of interest in theion to help them transition to electric flying.
