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.

Tesla analyst sees Full Self-Driving adoption rates skyrocketing: here’s why
“You’ll see increased adoption as people are exposed to it. I’ve been behind the wheel of several of these and the different iterations of FSD, and it is getting better and better. It’s something when people experience it, they will be much more comfortable utilizing FSD and paying for it.”
Tesla analyst Stephen Gengaro of Stifel sees Full Self-Driving adoption rates skyrocketing, and he believes more and more people will commit to paying for the full suite or the subscription service after they try it.
Full Self-Driving is Tesla’s Level 2 advanced driver assistance suite (ADAS), and is one of the most robust on the market. Over time, the suite gets better as the company accumulates data from every mile driven by its fleet of vehicles, which has swelled to over five million cars sold.
The suite features a variety of advanced driving techniques that many others cannot do. It is not your typical Traffic-Aware Cruise Control (TACC) and Lane Keeping ADAS system. Instead, it can handle nearly every possible driving scenario out there.
It still requires the driver to pay attention and ultimately assume responsibility for the vehicle, but their hands are not required to be on the steering wheel.
It is overwhelmingly impressive, and as a personal user of the FSD suite on a daily basis, I have my complaints, but overall, there are very few things it does incorrectly.
Tesla Full Self-Driving (Supervised) v14.1.7 real-world drive and review
Gengaro, who increased his Tesla price target to $508 yesterday, said in an interview with CNBC that adoption rates of FSD will increase over the coming years as more people try it for themselves.
At first, it is tough to feel comfortable with your car literally driving you around. Then, it becomes second nature.
Gengaro said:

Tesla Full Self-Driving take rates also have to increase as part of CEO Elon Musk’s recently approved compensation package, as one tranche requires ten million active subscriptions in order to win that portion of the package.
The company also said in the Q3 2025 Earnings Call in October that only 12 percent of the current ownership fleet are paid customers of Full Self-Driving, something the company wants to increase considerably moving forward.

Tesla scores major court win as judge rejects race bias class action
The ruling means the 2017 lawsuit cannot proceed as a class action because plaintiff attorneys were unable to secure testimony commitments from at least 200 workers.
Tesla scored a significant legal victory in California after a state judge reversed a class certification in a high-profile race harassment case involving 6,000 Black workers at its Fremont plant. The ruling means the 2017 lawsuit cannot proceed as a class action because plaintiff attorneys were unable to secure testimony commitments from at least 200 workers ahead of a 2026 trial, a threshold the judge viewed as necessary to reliably represent the full group.
No class action
In a late-Friday order, California Superior Court Judge Peter Borkon concluded that the suit could not remain a class action, stating he could not confidently apply the experiences of a much smaller group of testifying workers to thousands of potential class members. His ruling reverses a 2024 decision by a different judge who had certified the case under the belief that a trial of that size would be manageable, as noted in a Reuters report.
The lawsuit was originally filed by former assembly-line worker Marcus Vaughn, who alleged that Black employees at Tesla’s Fremont factory were exposed to various forms of racially hostile conduct, including slurs, graffiti, and instances of disturbing objects appearing in work areas. Tesla has previously said it does not tolerate harassment and has removed employees found responsible for misconduct. Neither Tesla nor the plaintiffs’ legal team immediately commented on the latest ruling.
Tesla’s legal challenges
While the decertification narrows the scope of this particular case, Tesla still faces additional litigation over similar allegations. A separate trial involving related claims brought by a California state civil rights agency is scheduled just two months after the now-vacated class trial date. The company is also contending with federal race discrimination claims filed by the U.S. Equal Employment Opportunity Commission, alongside several individual lawsuits it has already resolved.
For now, the reversal removes the large-scale exposure Tesla would have faced in a unified class trial, shifting the dispute back to individual claims rather than a single mass action. The case is Vaughn v. Tesla, filed in Alameda County Superior Court.

Tesla Holiday Update is incoming, and the wishlist is Merry and Bright
There are a handful of big wishes, and we’ve seen a lot of different requests out there based on what owners are saying on social media. Nevertheless, what Tesla should bring and what Tesla will bring are two different things.
Tesla’s Holiday Update is going to be on its way soon, and although we have no idea what the company is planning to implement into vehicles with the 2025 iteration.
However, the wishlist is extensive, and owners are hoping to get a vast array of new features, both useful and artificial. That’s the fun thing about owning a Tesla — not everything is necessary, and it’s okay for your car to be fun.
There are a handful of big wishes, and we’ve seen a lot of different requests out there based on what owners are saying on social media. Nevertheless, what Tesla should bring and what Tesla will bring are two different things.
🚨 All I Want for Christmas (in the Tesla Holiday Update) is:
1. More streaming platforms
2. Summon for Cybertruck
3. Easier Navigation adjustment for a preferred route instead of the optimal choiceWhat else? pic.twitter.com/qapS1jXAuB

In past years, Tesla has brought both useful things and fun things with the Holiday Update. The Custom Lock Sound, new Light Shows, and even High Fidelity Park Assist have all come in past updates, among many other things. But for 2025, people want even more, and here’s what we have seen most frequently thus far:
More Streaming Platforms
This is a personal request of ours, and it’s something that we feel is long overdue.
Sure, Netflix, Disney+, and Hulu are all great — but there’s a lot of meat left on that bone. HBOMax, Paramount+, and even YouTube TV would be a great option for those of us who have subscriptions and want to watch Live Events while Supercharging or eating in our cars.
The fact that Tesla has not added more platforms to its in-car Theater in a few years has been, dare I say, disappointing?
Full Self-Driving for Europe
This is something not even Santa can help with. Although his Elves are known for their high productivity, we’re not even sure they could convince European regulators to open the door for FSD’s entrance into the market.
Tesla deploys Unsupervised FSD in Europe for the first time—with a twist
FSD is definitely capable of handling European driving conditions, but regulators are truly dragging their feet through the mud with the approval process. Tesla has tested FSD in several countries in Europe, but nothing has been set in stone yet.
Deeper Grok Integration
Many owners have said something about how Grok is truly not super in-tune with the vehicles. This is something any owner will experience.
It seems Grok should be capable of handling all in-car requests; everything from changing the A/C to a specific temperature to adding a stop within the Navigation should be handled by Grok.
Instead, Grok cannot handle those things currently. You have to speak to the car itself using the microphone button on the steering wheel.
Interestingly, some vehicles already have the Grok logo replacing the microphone. It is likely the most realistic request of all.
‘Learn’ Mode for Full Self-Driving Arrival Options
Although it is great for public destinations, FSD still does not allow you to choose a set parking spot at your residence. It also does not allow you to choose preferences for parking in large parking lots.
Renters, and even those who live in purchased townhomes, often have assigned parking spots. Full Self-Driving v14 has done a great job of doing half the work, but there have been too many times when I’ve arrived home, the car pulls me into a spot, and I’m forced to manually back out and park in my assigned space.
Many people also do not like to park toward the entrance of a store, me included. Parking away from the front of a store eliminates parking congestion and usually is a safer bet for your vehicle to keep from being dinged by careless drivers who swing their doors open.
Navigation Adjustments
Sometimes you don’t want to turn left on the street the navigation chooses. Maybe you want to go a block down and check out that new Portuguese restaurant that just opened on the way to your next destination.
This is only possible currently by inputting a waypoint that would take you that way. Instead, the center screen could be opened, and the driver should be able to select an alternative route by simply touching a street they’d rather travel on.
