The headquarters of CATL, China’s fastest growing battery maker, lie on the edge of the city of Ningde, a stone’s throw from ponds where farmers raise carp and a street of cheap noodle restaurants and vehicle repair shops frequented by migrant workers. Inside the vast factory, battery parts move silently on automated conveyor belts. Signs on the walls encourage workers not to waste materials or time, or indulge in “unnecessary bending” for their own safety. The plant looks like lots of others dotted across the country. But with a valuation of $11.5bn, Contemporary Amperex Technology Ltd, to give it its full name, is anything but mundane. It is set to become China’s Panasonic — a national champion — and a key part of Beijing’s ambitious plan to remake the global battery market and exploit rising demand for electric cars. “We want to become a leading enterprise, like the front carriage of a train, driving an entire supply chain,” says Neill Yang, CATL’s marketing director. His office overlooks cranes and cement mixers, which are building a dormitory and offices to house 20,000 workers.
