Sodium-ion batteries are a commercially viable option for sustainable energy storage, but their performance at low temperatures remains underexplored. Here, the authors present a sodium-ion battery pouch cell designed for ultra-low temperatures, demonstrating its performance in laboratory conditions at -25 °C and -50 °C, in the presence of wind and snow, and in combination with a solar cell at -100 °C.
