Sodium Battery Fast Charging: 4-Minute Charges and 6,000-Hour Cells

For decades, the battery industry has operated on a quiet assumption: sodium-ion batteries are the affordable also-ran, fine for grid storage but far too slow and too weak for anything demanding. That assumption is now being dismantled one laboratory result at a time. In May 2026, researchers at Southeast University in China published a sodium […]
