Thermal runaway solved? Non-flammable sodium battery passes extreme safety testing
SMRTR summary
Hyundai Motor Group partnered with US startup UNIGRID to test a non-flammable sodium-based battery that passed extreme safety testing with zero fires. The sodium chromium oxide cells lasted up to 30,000 cycles, roughly 25 years, and performed reliably from -20°C to 60°C, making them ideal for powering Hyundai's global factories safely.
