Tesla Inc. is looking to build a battery plant in the U.S., according to people familiar with the matter, in what would likely be a controversial arrangement with China’s dominant electric-vehicle battery manufacturer.

The EV maker discussed plans involving Contemporary Amperex Technology Co. Ltd. with the White House in late March, said the people, who asked not to be identified revealing private conversations. Tesla representatives sought clarity on the Inflation Reduction Act rules that the Biden administration is finalizing this week, according to some of the people. Rohan Patel, the company’s senior global director of public policy, was among those involved with the discussions, one of the people said.

Tesla wants to pursue a deal similar to one that Ford Motor Co. announced last month in Michigan with the battery maker, known as CATL, to construct a plant wholly owned by the U.S. automaker, according to the people.

Representatives of Tesla, CATL and the White House didn’t immediately respond to requests for comment. Patel also didn’t respond.

CATL shares rose as much as 2.3% in early trading in Shenzhen on March 31.  

Tesla is in expansion mode, deploying its $22 billion in cash to crank up production volumes and lower costs as it faces increased competition. CATL, which makes lithium iron phosphate batteries, a chemistry that is cheaper than the nickel-based batteries used in the West, is key to that plan.

The automaker is considering building the battery plant in Texas to supply its EV assembly plant there, though a location hasn’t been finalized, some of the people said. Like the Ford deal structure, Tesla would own and operate the factory while licensing the technology from CATL.

The auto industry has been lobbying to influence how the U.S. Treasury Department will interpret requirements in President Joe Biden’s signature climate package. The law is intended to wean the U.S. off its dependence on China for battery materials by incentivizing a U.S.-based supply chain for EVs. One specific clause that has been the object of intense lobbying is 30D, which is designed to withhold consumer tax credits for EVs made with a certain amount of China-linked materials in their batteries.

Ford’s deal has provoked ire from lawmakers including Democratic Senator Joe Manchin of West Virginia and Republican Senator Marco Rubio of Florida, who argue that it allows the Chinese company to benefit from U.S. subsidies. Ford has said CATL wouldn’t receive any US tax dollars from the deal.

Barclays Plc analyst Dan Levy said in a research note that Tesla may get some political push-back to a deal with CATL, similar to what Ford has seen.
