Sodium-ion batteries have lower density but are cheaper and perform better in cold weather.

The new Yiwei EV reportedly uses cylindrical sodium-ion cells from HiNA Battery. JAC assembles the batteries in the company’s modular UE (Unitized Encapsulation) honeycomb structure, similar to CATL’s CTP (cell-to-pack) and BYD’s Blade. The layout can provide for greater stability and performance.
