China's leading power battery maker, Contemporary Amperex Technology Co Ltd, announced Thursday it has signed a volume production supply pricing agreement with US carmaker Tesla, according to China Securities Journal.
CATL said "the cooperation is not an 'intentional agreement'", and "Tesla will purchase lithium-ion power batteries from CATL."
Investors shall rely on its official announcement, the company said.
According to a previous Reuters report on Tuesday, Tesla is in talks to use CATL's cobalt-free batteries in cars made at its Shanghai plant, citing people familiar with the matter.
The US automaker will adopt the so-called lithium iron phosphate batteries in its lineup so as to cut cost, Reuters said.
CATL saw its shares a sharp surge by the midday on Feb 20, gaining 5.32 percent to 161.35 yuan per share ($22.98).
