For decades, sodium-ion batteries lived in the shadow of their lithium-ion counterparts. But today, as the world races toward renewable energy and confronts lithium shortages, sodium is staging a remarkable comeback.

​"We're not just improving batteries—we're redefining energy storage from the ground up," says a lead engineer at China’s Gotion High-Tech, holding a cell that charges in minutes and withstands violent abuse.

“True competitiveness lies not in short-term bets on trends, but in long-term commitment to independent R&D,” declares a Haichen Energy Storage executive, holding a battery cell large enough to power a neighborhood for hours.
