Tesla is working on new battery technology that CEO Elon Musk says will enable the company to make sleeker, more affordable cars that can travel much longer distances on a single charge.
But the battery breakthroughs unveiled Tuesday at a highly anticipated event seemed to disappoint Wall Street, with the entrepreneur saying it will take years to develop the enhanced batteries. Investors were hoping Tesla's technology would mark an even bigger leap forward and propel the company's soaring stock to greater heights.
Tesla's shares shed more than 6% in extended trading after Musk's presentation, with the stock down another 8% on Wednesday. That deepened a slump that began during Tuesday's regular trading session as investors began to brace for a potential letdown. Musk raised those worries with a series of tweets Monday warning that Tesla's new battery tech might not be ready for high-volume production until 2022.
"The stock is down on knee-jerk reaction as the biggest disappointment of the event from the Street's perspective was around no million-mile battery announcement in our opinion as this was widely expected to be unveiled," Wedbush analyst Dan Ives said in a research note.
But Ives remain bullish on Tesla's future, citing the company's to make its vehicles more affordable. The company's shares remain on a tear this year, up more than 366%.
Musk reiterated that timetable during Tuesday's showcase and said it might take up to three years before the battery technology translates into a new Tesla model selling for $25,000. That would be a dramatic markdown from Tesla's cheapest car now, the Model 3, a sedan that starts at $35,000 but usually ends up costing buyers more than $40,000.
"We don't have a truly affordable car, and that is something we want in the future," Musk said during the event.
New battery design
Tesla unveiled its proprietary cell named 4680 — named after its cylindrical measurements of 46 millimeters by 80 millimeters — which offers 6 times the power of its previous cells, 16 times more range, and 5 times the energy capacity, according to Ives in his research note, who believes the new cell to be "a linchpin to [Tesla's] future EV vision with significantly reduced costs and much longer ranges."
Tesla estimates that a new "biscuit-tin" battery cell design and a further 18% from its new smaller, more efficient Terafactory manufacturing design.per kilowatt-hour can be achieved with the
The new battery will also be cobalt-free as reported by The Verge. Costly and rare, the mineral is used in virtually all batteries in common devices, including cellphones, laptops and even electric vehicles. A file last year accused some of the biggest technology firms in the United States of complicity in the death and maiming of hundreds, if not thousands of African children who mine cobalt. Tesla was one of the defendants named in the suit, along with Apple, Google parent company Alphabet, Microsoft and Dell.
Besides lowering the price, Musk promised the new battery technology would help Tesla reduce the size of its vehicles by about 10% and extend their range by 56%. That projection implies the Tesla cars using the new batteries will be able to travel 500 miles (800 kilometers) or more on a single charge, surpassing the distance many gas-combustion cars can traverse before needing to refuel.
Shareholders in cars
Musk took the stage before a mostly online audience, although there was a small group of shareholders who won a lottery for the right to sit in Tesla vehicles parked in a lot near the company's Fremont, California, factory located about 40 miles (64 kilometers) southeast of San Francisco.
"It is a little hard to read the room with everyone in cars," Musk joked as he began his presentation during an early phase of the event that was devoted to Tesla's annual meeting of shareholders.
But the shareholders in attendance frequently beeped their horns to provide a different form of applause as Musk rattled off Tesla's accomplishments since the company held its last annual meeting 15 months ago.
Since then, Tesla has posted four consecutive quarters of profits to reverse a long history of losses, while boosting its production and laying the groundwork for future expansion by opening or beginning work on three more factories in Shanghai, Berlin and Austin, Texas. All that progress has caused Tesla's stock price to soar by fivefold so far this year and boost the company's market value to nearly $400 billion.
No one has benefited more from the run-up than Musk, who has seen his estimated wealth climbed to $89 billion — the fifth-largest fortune in the world, based on estimates by Forbes magazine.
"What happens when companies get bigger is things tend to slow down. We are going to speed up," Musk said Tuesday.
One step ahead
He said he believes Tesla will remain a step ahead of its competition in the electric vehicle market and persuade more consumers to abandon gas-combustion cars with its new battery technology. The breakthroughs that he outlined Tuesday involve some highly technical changes to the composition and design of batteries, along with new manufacturing processes.
Even as Tesla tries to set new standards in batteries, Musk made it clear that the company will also continue to rely on Panasonic and other suppliers.
Musk has a history of being too ambitious in his promises. For instance, 17 months ago, he bragged that Tesla was on the verge of breakthroughs in autonomous driving technology that would enable the company to deploy a fleet of robotic taxis by the end of this year.
He has since backpedaled slightly from that goal, although Tuesday he said he believes Tesla's $25,000 car will be capable of driving on its own.
