Chinese EV firms race for new tech

Chinese EV manufacturers BYD and CATL are competing to improve charging speeds and battery technology, with BYD pursuing flash-charging and CATL focusing on fast charging and battery-swapping. Next-generation technologies like solid-state and sodium-ion batteries face delayed timelines. Meanwhile, China's slowing domestic economy is pushing EV makers to expand internationally, with BYD negotiating with Stellantis to acquire European manufacturing facilities.
