World’s first sodium-ion electric haul truck gets to work in China

A mining company in China has put the world's first sodium-ion electric haul truck to work at a limestone mine. The truck, made by Tonly Heavy Industry with battery maker Hina Battery, uses a 676 kWh sodium-ion battery, a technology that stores energy without lithium. The battery reportedly charges from empty to full in under minutes and can handle 8,000 charge cycles, far more than typical lithium batteries manage.

This has nothing to do with rebates or your house, but it points to where battery technology is headed. Sodium-ion batteries hold up better in extreme cold than lithium-ion ones, which matters for these trucks working in northern China where nights can drop to -20°C. That same cold-weather advantage has already shown up in electric school buses and other vehicles tested in harsh winters, which have outperformed diesel equipment that struggles to even start in deep cold.

For homeowners, the relevant thread is a distant one: sodium-ion batteries could eventually become a cheaper, more available alternative to lithium for things like home battery storage, since sodium avoids some of the supply and cost issues tied to lithium. Nothing here is a product you can buy for your home yet, but it is a sign that battery options beyond lithium are moving from labs into real-world, heavy-duty use.
