Contemporary Amperex Technology Co. Ltd. unveiled a sodium-ion battery Thursday, a type of lower-density cell that uses cheaper raw materials than batteries made from lithium-ion metals.
As well as a first generation of sodium batteries, the Ningde, Fujian-based company also launched a battery-pack solution that can integrate sodium-ion cells and lithium-ion cells into one case, compensating for the energy-density shortage of the former while preserving its advantages.
