Researchers achieve EV battery breakthrough with silicon-based materials and gel electrolytes, moving closer to a 1,000-kilometer range on a single charge.
Projections from BNEF suggest that sodium-ion batteries could reach pack densities of nearly 150 watt-hours per kilogram by 2025. And some battery giants and automakers in China think the technology is already good enough for prime time. 1
because it has the potential to be sustainable, cheaper, and less explosive. It's not technically superior as far as energy density goes, but right now batteries are prohibitive in many applications, moreso due to cost than weight.
