(Reuters) – Tesla Inc <TSLA.O> Chief Executive Officer Elon Musk said on Monday improvements unveiled at the electric-car maker’s “Battery Day” event would not reach serious high-volume production until 2022.
The company’s shares fell nearly 4% to $432 in extended trade.
“This affects long-term production, especially Semi, Cybertruck & Roadster, but what we announce will not reach serious high-volume production until 2022,” Musk tweeted, ahead of the event scheduled to take place on Tuesday.
Musk also said Tesla intends to increase battery cell purchases from suppliers Panasonic <6752.T>, South Korea’s LG Chem <051910.KS> and China’s CATL <300750.SZ>, and possibly with other partners as well.
Despite the cell suppliers’ maximum speed, the automaker still expects significant shortages in 2022 and beyond, he added.
Many analysts expect Musk to unveil battery improvements at the event, extending the automaker’s lead over General Motors <GM.N>, Volkswagen <VOWG_p.DE> and other rivals.
