[BYD's First Global Mass Production Line for Sodium-ion Batteries Goes into Operation] On July 16, BYD's 30Gwh sodium-ion battery mass production line in Xining, Qinghai officially commenced operations. The battery energy density reaches 160Wh/kg, with low-temperature performance improved threefold compared to LFP batteries, and costs reduced by 30%. The establishment of this production line marks the transition of sodium-ion batteries from theoretical breakthroughs to large-scale industrialisation, particularly offering significant advantages in energy storage systems (ESS) and new energy vehicles (NEVs) in extremely cold northern regions.
