Tesla’s new battery expert will do “whatever it takes” to improve battery performance

World renowned battery research Jeff Dahn will join forces with Tesla Motors on June 8. His mission is to do “whatever it takes” to improve the science behind the batteries Tesla relies on for its cars and energy storage devices.

Jeff Dahn is a world renowned battery researcher who teaches at Dalhousie University in Nova Scotia. According to the university’s website, he “is recognized as one of the pioneering developers of the lithium-ion battery that is now used worldwide in laptop computers and cell-phones. Dahn’s recent work has concentrated on the application of Combinatorial Materials Science methods to battery and fuel cell materials problems. He is the author of over 500 refereed journal papers and co-inventor of 58 inventions with patents issued or filed.”

Up until know, Dahn has been working exclusively doing research for 3M and the Natural Sciences and Engineering Research Council of Canada to develop longer-lasting, lower cost lithium-ion battery cells, but his agreement ends on June 7. On June 8, he will join forces with Tesla Motors and work exclusively for it. He says his mandate is to do “whatever it takes” to improve the company’s battery performance.

Dahn is a proponent of a different form of battery chemistry than Tesla currently uses. Called lithium nickel manganese cobalt oxide, or NMC, it has lower capacity than lithium cobalt batteries but higher specific power and longer life, according to Battery University. Elon Musk has publicly ridiculed NMC chemistry. Tesla is firmly committed to lithium nickel cobalt aluminum oxide chemistry, or NCA.

Does hiring Dahn indicate that Tesla may be considering a shift in its core battery technology? Dahn told Quartz recently that his mission at Tesla is the same as every other battery researcher in the world — low cost, high energy density, and long battery life. But “whatever it takes,” an operational mantra he said he picked up in conversation with Kurt Kelty, Telsa’s battery director, will be his rule. “Those are the goals, and that’s how we’re going to do it,” Dahn said. “We’re open to anything that makes sense.”

A willingness to consider all possible options is a characteristic that defines Elon Musk. It’s astonishing that Musk and Tesla would consider options that challenge the battery technology they have been committed to for years, but if that’s what it takes to keep Tesla ahead of the competition, that’s what they are prepared to do.

Why Tesla’s Q4 performance could shock many after incredible Q3

There is still some residual impact to be felt as we enter Q4, and there is a potential shock coming to many investors as it could be stronger than what many think:

Tesla reported vehicle deliveries and energy deployments for the third quarter of 2025 today, blowing analyst estimations from Wall Street firms completely out of the water with its strongest three-month performance in company history.

The strong performance, which resulted in nearly half a million vehicle deliveries in the quarter, was largely driven by the momentum of the EV tax credit, which expired at the end of September, marking the end of the $7,500 discount that was previously available.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025

This was a massive contributor to Tesla’s record-high in vehicle deliveries, as consumers rushed to take advantage of the credit.

There is still some residual impact to be felt as we enter Q4, and there is a potential shock coming to many investors as it could be stronger than what many think:

EV Tax Credit Deliveries Will Continue Through Q4

Despite the credit’s expiration, people will still be able to take advantage of it because the IRS changed the rules mid-quarter.

Prospective buyers can utilize the credit after September 30 if they place an order for an EV and make a marginal payment on the car.

Tesla’s $250 order deposit qualified as the marginal payment, so as long as the order was submitted before the end of the day on September 30, they could still take delivery in Q4 or even Q1 and still take advantage of the credit.

Tesla set to win big after IRS adjusts EV tax credit rules

With the Model Y Performance launching in the U.S. on September 30, that undoubtedly contributed to some orders. However, there are likely many people who ordered in the latter portion of Q3 and have not yet taken delivery. These will all contribute to Q4 delivery figures.

Seasonal Holiday Boost

Tesla traditionally has its strongest quarters in Q4, as the company typically introduces initiatives such as price cuts, incentives, and other offers to close out the year strong.

Car buyers are more likely to jump at these offers as well, as gifts for either themselves or others. What Tesla does in the final quarter of the year is usually boosted by whatever types of offers it can make.

Affordable Model Production Ramp

Tesla is likely preparing for the launch of its affordable model, which is essentially a stripped-down Model Y.

Some rumors have been circulating within the community, indicating that the company is nearing the sale of this vehicle, which is coded within Tesla’s website as the “Model Y Standard.”

If Tesla is able to lock in some good pricing on its affordable model, Tesla could see its quarterly figures return to QoQ growth, something that the company has not had in a few years.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025

As per Tesla’s Q3 2025 vehicle delivery and production report, the bulk of the company’s numbers came from its mass-market lineup.

Published

on

Tesla (NASDAQ:TSLA) reported record-breaking results for the third quarter of 2025, producing 447,450 vehicles and delivering 497,099 units worldwide. 

The company also deployed 12.5 GWh of energy storage products, setting a new record in its fast-growing energy business.

Model 3/Y domination

As per Tesla’s Q3 2025 vehicle delivery and production report, the bulk of the company’s numbers came from its mass-market lineup. The Model 3 sedan and Model Y crossover accounted for 435,826 units produced and 481,166 delivered in the quarter. This is quite impressive considering that both the Model 3 and Model Y are still premium-priced vehicles with numerous competitors that are significantly more affordable.

Other models, including the Model S, Model X, and Cybertruck, contributed 11,624 vehicles produced and 15,933 delivered. Beyond vehicles, Tesla’s energy business posted its best quarter to date, deploying 12.5 GWh of storage systems.

Q3 2025 earnings call date

Tesla’s third-quarter results are extremely impressive, and they exceed Wall Street’s estimates by a significant margin. As per Benchmark analyst Mickey Legg, who had a delivery estimate of 442,000 vehicles in Q3, Wall Street consensus was at 448,000 units. Even more optimistic analysts estimated that Tesla would only post deliveries in the mid-460,000s.

Investors will gain further insight later this month when Tesla reports full financials for the quarter. The company will release Q3 2025 earnings after market close on October 22, followed by a Q&A webcast at 4:30 p.m. Central Time.

Elon Musk is halfway towards becoming the world’s first trillionaire

Musk’s fortune remains heavily tied to Tesla, which has rallied nearly 100% since April.

Elon Musk has reached a new milestone by becoming the first individual in history to achieve a net worth of $500 billion. ForbesReal-Time Billionaires tracker confirmed the record Wednesday afternoon after Tesla stock gained nearly 4%, adding an estimated $9.3 billion to Musk’s net worth in a single day. 

He now sits more than $150 billion ahead of Oracle co-founder Larry Ellison, whose net worth also stands at a very impressive $350 billion.

Tesla stock leads wealth surge

Musk’s fortune remains heavily tied to Tesla, which has rallied nearly 100% since April, when the CEO announced he would step back from outside roles to focus more on the EV maker. The company’s market capitalization is back within 10% of its all-time peak, lifting the value of Musk’s 12% stake to about $191 billion. 

Beyond this, his 2018 compensation package, which was rescinded by a Delaware judge last year but is still under appeal, could unlock additional stock worth more than $130 billion if reinstated, Forbes noted. Investors see Musk’s refocused leadership as a stabilizing force for Tesla as it pursues ambitious global growth. Tesla has also proposed a new compensation plan for Musk that could bring the company’s market cap to $8.5 trillion and add an additional $900 billion to the CEO’s net worth. 

SpaceX and xAI boost portfolio value

While Tesla drives much of his wealth, Musk’s stakes in SpaceX and xAI have added significant upside to his net worth. SpaceX, his private rocket company, recently hit a $400 billion valuation in a private tender offer, valuing Musk’s 42% stake at $168 billion. Meanwhile, xAI Holdings, which merged with social platform X earlier this year, is worth an estimated $113 billion, giving Musk another $60 billion on paper.

These ventures, combined with Tesla’s resurgence, have pushed Musk’s net worth past the half-trillion-dollar mark and highlighted his reach across multiple industries, from clean energy to space, artificial intelligence, brain implants, and tunneling.
