Five Cool Tech Demos From the ARPA-E Summit

Cars That Think

Gas Li-ion batteries thwart extreme cold South 8 Technologies demonstrates the cold tolerance of its Li-ion battery by burying it in ice at the 2024 ARPA-E Energy Innovation Summit. That’s a big improvement on conventional Li-ion batteries, which start to degrade when temps reach 0 °C and shut down at about –20 °C.
