Tesla and Jeff Dahn once teased the development of a battery cell that would last one million miles. For years, Tesla fans, enthusiasts, and those interested in battery technology were heavily invested in Dahn’s research, which led to the idea that the batteries in electric vehicles would outlast the vehicles themselves.
Dahn’s office at Dalhousie University features a lineup of heavy-hitting scientists and engineers who have all worked cohesively with Tesla and its research chair Chongyin Yang.
One of them is Michael Metzger, who has been with Dahn’s lab at Dalhousie since January 2021, when Tesla and the battery research facility renewed their partnership.

Over the years of the Tesla-Dahn partnership, the automaker, as well as the team of engineers, have developed strategies to promote battery longevity. Various patents, like an electrolyte solvent and new revolutionary electrode designs, were geared toward helping battery cells reach thousands of life cycles, enabling one million miles of operation.

In a recent interview with Electric Autonomy, Metzger detailed the various developments that have come from working with Tesla over the past several years. One of the things Metzger shared was the various battery cell designs that the Dalhousie battery team has engineered for Tesla.
Among the designs and chemistries, LFP (lithium iron phosphate) and NMC (nickel manganese cobalt) are two that were discussed during the interview. While LFP is considered second-best, NMC has taken the top spot, according to Metzger.
Initially, it was capable of thousands of cycles, but it now has the capacity to run 19,500 cycles and counting.
“Each cycle is 300 kilometers. So, if it were at 20,000 cycles, it would be 6 million kilometers,” Metzger said in the interview.
6 million kilometers is equal to 3,728,227 miles. The technology has nearly quadrupled in the past few years.
Dahn said in an interview with the Nickel Institute earlier this year that the team had developed and demonstrated batteries that were capable of these massive numbers.
We may be some years away from these batteries being put into a consumer setting. Additionally, NMC batteries feature cobalt, a controversial material that has proven benefits in terms of cell cycle stability.
Automakers are opting for LFP cells in their lower-range vehicles. Tesla transitioned to these packs in Standard Range EVs in 2021.

Analyst: Elon Musk’s $1 trillion Tesla pay deal modest against robot market potential
Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment.

Morgan Stanley analyst Adam Jonas, one of Wall Street’s most ardent Tesla (NASDAQ:TSLA) bulls today, has described Elon Musk’s newly proposed $1 trillion performance-based compensation package as a “good deal” for investors.
In a note shared this week, Jonas argued that the package helps align the interests of Musk and Tesla’s minority shareholders, despite its shockingly high headline number.
Future market opportunities
Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment. “Yes, a trillion bucks is a big number, but (it) is rather modest compared to the size of the market opportunity,” Jonas wrote. He added that the humanoid robot market could ultimately surpass the size of today’s global labor market “by a significant multiple.”
“We have entertained scenarios where the humanoid robot market can exceed the size of today’s global labor market… by a significant multiple,” Jonas wrote, as shared on X by Tesla watcher Sawyer Merritt.
The analyst likened the arrival of AI-powered robotics to the transformative effect of electricity, noting that “contemplating future global GDP before AI robots is like contemplating global GDP before electricity.” The Morgan Stanley analyst’s insights align with the idea that as much as 80% of Tesla’s future valuation could be tied to its Optimus humanoid robot program.
Elon Musk’s pay package
Tesla’s board has tied Elon Musk’s proposed compensation package to some of the most ambitious targets in corporate history. The 2025 CEO Performance Award requires the automaker’s valuation to soar from roughly $1.1 trillion today to $8.5 trillion over the next decade, a level that would make Tesla the most valuable company in existence.
The plan also demands a leap in Tesla’s operating profit, from $17 billion in 2024 to $400 billion annually. It also ties the CEO’s compensation to a number of product milestones, including the delivery of 20 million vehicles in total, 10 million active Full Self-Driving subscriptions, 1 million Tesla Bots, and 1 million Robotaxis in operation. Tesla’s board emphasized that Musk’s leadership was fundamental to achieving such ambitious goals, with Chair Robyn Denholm noting the award would align the CEO’s incentives with long-term shareholder value.

Tesla China posts strongest registrations of Q3 so far with first Model Y L deliveries
Tesla posted 14,300 insurance registrations in China during the week of September 1–7.

Tesla posted 14,300 insurance registrations in China during the week of September 1–7, a 14.4% increase from the previous week’s 12,500 units.
The figure marks Tesla’s highest weekly performance so far this quarter so far, despite the company’s year-over-year figures still being below 2024’s numbers.
Weekly registrations
The week’s registrations broke down to 5,000 Model 3s and 8,400 Model Ys, including the first 900 units of the newly launched Model Y L variant, as per estimates from industry watchers. On a quarterly basis, Tesla China is tracking 41.3% growth compared to the previous quarter, which bodes well for the company’s results this Q3 2025.
For the month of August, Tesla sold 57,152 vehicles in China, down 9.93% from the same period in 2024 but up 40.7% from July’s 40,617 units, according to the China Passenger Car Association (CPCA). Year-to-date, Tesla’s China sales are 7.2% lower compared to the previous year.
Model Y L first deliveries
The week ending September 7 was the first week that included the newly released Model Y L, a six-seat extended wheelbase version of the company’s best-selling all-electric crossover. Industry watchers estimate that last week, the first 900 units of the Model Y L have been registered, though this number is expected to increase in the coming weeks as deliveries of the vehicle hit their pace.
Citing information from a Tesla store in Beijing, Chinese media outlet Cailianshe stated that the Model Y L has been seeing a lot of interest among car buyers. “(The Model Y L) is selling very well. Since its launch, 120,000 orders have been received, with nearly 10,000 orders placed every day. The first batch of customers began receiving deliveries in the past two days,” a Tesla representative stated.

Tesla launches MultiPass to simplify charging at non-Tesla stations
With the new service, Tesla owners can activate charging either through the Tesla app or by using their existing Tesla key card.

Tesla has introduced MultiPass, a new feature that allows owners to use their Tesla account to charge at non-Tesla charging stations.
The service launched this week in the Netherlands, giving drivers the ability to find chargers, start sessions, and view charging history directly within the Tesla app.
Streamlining third-party charging
With MultiPass, Tesla owners can activate charging either through the Tesla app or by using their existing Tesla key card. This eliminates the need for separate accounts or additional cards from third-party networks. Tesla Charging highlighted the convenience of managing charging sessions in one location in a post on X, while Max de Zegher, Tesla’s Director of Charging for North America, emphasized that the update removes unnecessary friction.
“Nobody likes creating more accounts with payment details and passwords. For charging, this can even mean needing a third-party charging card mailed to your house. Starting in the Netherlands today, your Tesla App and your existing (!) Tesla keycard can start charging at third-party chargers. We’ll expand this to more countries quickly if customers love it. To make ownership effortless, the Tesla App should really be the only thing you need,” the Tesla executive wrote in a post on X.
Third-party payments and a familiar name
Tesla owners could pay for their third-party charging session with their Tesla accounts, as per the electric vehicle maker on its official website. Payments are drafted from users’ default payment method in the Tesla App, though charging costs will still vary depending on the third-party charger that is used.
Interestingly, the MultiPass name also echoes a pop culture reference. In the 1997 sci-fi film The Fifth Element, Leeloo Dallas-505 carried a futuristic “Multipass” smart card that functioned as her ID, passport, and ticket to space travel. Her accented repetition of “Multipass!” became one of the film’s most memorable lines, and it highlighted the card’s all-in-one convenience.
Tesla has not provided a timeline for Multipass’ U.S. rollout, though the service could become an important addition to the growing but often fragmented landscape of DC fast charging.
