China’s Contemporary Amperex Technology (CATL), the world’s largest producer of electric vehicle batteries, has unveiled an upgraded battery that promises an even longer range than rival BYD’s cutting-edge technology.

CATL, which is the world’s largest EV battery manufacturer by a long way, has also joined in the competition, announcing that its next-generation 'Shenxing' LFP (lithium-ion phosphate) battery can add over 320 miles in just five minutes from the appropriate but currently thin-on-the-ground 1MW fast charging outlets.

The world's largest EV battery company also teases two other jaw-dropping technologies, though it's unclear if US consumers will ever get to try them.
