At its April 21 Tech Day in Shanghai, CATL unveiled two major innovations poised to accelerate the EV transition past internal combustion engines. Highlights included the debut of CATL’s second-generation Shenxing ultra-fast charging battery, outperforming BYD’s Super e-Platform, and a strategic push to mass-produce sodium-ion batteries. These two technologies extend CATL’s lead over BYD while positioning sodium-ion batteries as a safer, more affordable challenger to lithium’s dominance in the EV supply chain.
