Austin, Texas-based startup Group1 boasts a star-studded govt suite. Chief Product Officer Dr. Leigang Xue invented Potassium Prussian White (KPW) cathode supplies in 2017 on the laboratory of the legendary John B. Goodenough on the College of Texas. The corporate, which made its debut at Professor Goodenough’s a hundredth birthday celebration, is working to commercialize cathode supplies for novel potassium-ion batteries.
The corporate says potassium-ion batteries (KIBs) provide charging velocity, effectivity and security benefits over lithium-ion batteries (LIBs, in the event you should), and it’s utilizing a machine learning-driven course of to optimize KIB manufacturing.
“Trade adoption of Group1’s KPW cathode supplies can be accelerated due to the supplies’ match with present graphite anode supplies, electrolytes, cell design, and manufacturing for lithium-ion batteries,” says the corporate. “Which means that LIB producers don’t want to vary their present infrastructure, as it may already be used to supply KIBs which might be enabled by KPW cathode supplies.”
Group1 says its KPW cathode supplies provide a number of benefits over different lithium alternate options. The uncooked supplies utilized by Group1 to create KIBs are broadly obtainable each within the US and internationally. Group says the potassium utilized in KPW cathode supplies is 1,000 occasions extra considerable within the earth than lithium, and 20 occasions extra reasonably priced. Group1 additionally makes use of different considerable, domestically-available minerals.
Group1 says its KIBs will ship security advantages over LIBs primarily based on using safer electrolytes and oxygen-free supplies. They’re additionally extra environment friendly and faster-charging, as potassium ions in electrolytes have a smaller dimension and better mobility in comparison with lithium ions.
“The demand for lithium-ion batteries is spiking rapidly, and our lithium provides will quickly be incapable of assembly that demand,” mentioned Group1 CEO Alexander Girau. “Potassium-ion batteries can present a viable various to bridge this provide hole. We’re proud to be the primary firm available on the market commercializing potassium Prussian White cathode supplies to create safer, rapidly charging, extra environment friendly and sustainable potassium-ion batteries.”
