BEIJING – It is the world’s biggest battery maker, it powers electric vehicles for Tesla, Volkswagen and BMW, and its EV technology is miles ahead of US offerings, say experts

And the next frontline in the economic conflict may be the most fundamental yet: a fight for power itself.

A Chinese company that most people have never heard of is at the heart of the global race to store the clean energy needed to power the green transition in the US and the rest of the world.

China’s Contemporary Amperex Technology Co Limited, or CATL, is an energy storage specialist that is the world’s largest battery maker for electric vehicles (EVs). But despite the fact that the company controls nearly two-fifths of the world’s EV battery market – and has powered cars made by brands including Tesla, Volkswagen and BMW – it has long flown under the radar of US politics. Until now.

In February, Duke Energy, a US energy company that serves more than 8 million customers, said it was phasing out the use of CATL batteries. Duke said it would replace the CATL products with technology from a “domestic or allied nation supplier.”

The decision came after lawmakers had raised concerns about the use of CATL batteries at a Marine Corps base, Camp Lejeune, in North Carolina. Duke, which provides electrical infrastructure to the military base, disconnected the CATL batteries in December and now plans to decommission them entirely, as well as phase them out from civilian projects.

Ford has also come under fire for doing business with CATL. A deal between the two companies to build a factory in Michigan to produce low-cost lithium iron phosphate batteries for EVs using CATL technology has repeatedly been questioned by US lawmakers. Marco Rubio, the vice-chairperson of the Senate intelligence committee, said the plan would bring “America’s greatest geopolitical adversary into the heartland” . In November, Ford scaled down its plans for the plant, reducing its capacity by about 40%.
