Tesla CEO Elon Musk has used Twitter to respond to a Reuters report published yesterday that indicated the company was in talks with Samsung SDI to supply batteries for its car and energy storage products. Musk clarified that Tesla is "working exclusively" with Panasonic to make the cells for its upcoming Model 3 electric car, and that "news articles claiming otherwise are incorrect."

Musk followed up with a tweet that stated that the batteries in Tesla's Model S and Model X vehicles "are also Panasonic." In a statement sent to The Verge, a Tesla spokesperson said the company "works with all the leading battery suppliers around the world," but refused to comment on details of programs with specific suppliers. "Panasonic has been our battery cell supplier throughout the Model S and Model X programs," the statement reads, with Tesla "work[ing] very closely with Panasonic to ramp up battery cell production at the Gigafactory for Model 3."

The Reuters report suggested that a potential Samsung SDI deal would help cover the unexpected demand for Tesla's Model 3, announced earlier this year and due in 2017, but also considered the possibility that the two companies may be in discussions to supply the cells for Tesla's energy storage products, such as its Powerwall. Musk did not address the topic in his tweets, leaving room for Tesla to offload battery production for Tesla Energy products to another company while it focuses its huge Reno Gigafactory on the increased production of Model 3 cells.
