Tesla’s approach to battery technology keeps it ahead in the EV industry
Tesla’s dominance in the growing electric vehicle (EV) industry is largely attributed to its unique approach to its battery technology. The engineering behind the all-electric car maker’s cylindrical cells speaks for itself in terms of the performance and range achieved, but in a recent interview with a battery technology researcher, a few things detailed about Tesla’s batteries stood out in particular.
Ravindra Kempaiah is a Ph.D. scholar at the University of Illinois Chicago focusing on advanced battery materials for his thesis. In his interview with Tesla owner and host of All Things EV, Sean Mitchell, Kempaiah explained lithium-ion technology in EVs and the primary issues faced in their development. Overall, the biggest challenge is balancing the three main components in battery production: energy density, cost, and cycle life. Increasing one area will significantly impact the other, and the ideal equation is always being sought after. For example, if you increase energy density for higher range and lower cost, the cycle life takes a major hit. If you increase density and life cycle, the battery alone can cost as much as $100k, as described by Kempaiah.
“We always want more range. We always want higher cycle life. We want our batteries to last 15-20 years and the car to go 500 miles, but this is a problem every battery scientist has faced for the last 30 years,” Kempaiah commented in the interview.
Tesla deals with the same balancing act as other battery-electric car makers; however, there are key factors which seem to have kept the company ahead in the industry.
First, Tesla’s choice of cylindrical cells sets it apart from every other electric vehicle on the market. This provides several advantages that drive performance, flexibility, and cost control. Notably, Rivian is also using cylindrical cells, although their vehicles are not yet under production.
Out of the three types of cells available (cylindrical, prismatic, and pouch cells), cylindrical is the most cost-effective to produce. Namely, the cost per kWh is lower in cylindrical cells versus other types. The metallic jacket around the 18650 and 2170 cylindrical cells used in the Tesla Model S/X and Model 3, respectively, acts as scaffolding and provides structural rigidity to the battery. Additionally, in high powered situations, current draw and distribution of power is over the entirety of the battery pack instead of concentrated in a certain section, according to Kempaiah.
Second, Tesla uses a liquid-cooled thermal management system to manage battery temperatures whereas other automakers take a more economical air cooling approach. By adjusting the temperature of the battery pack, Tesla is able to ensure that cells are operating in their most efficient and optimal states, thereby maximizing battery longevity as well as performance. While reducing cost is an important factor in accelerating the growth of the electric vehicle market, Tesla’s investment in thermal management technology provides an upside for owners who may be looking for longevity and long-term affordability of their cars.
Third, Tesla has actively sought to limit the amount of cobalt it uses in its batteries and already uses less of the element than other companies in the Model 3 batteries. The scarcity of cobalt and its mining sources have subjected it to socioeconomic situations that are more than problematic in the United States, i.e., child labor and similar abuses are widespread in its sourcing. With this in mind, Tesla has been working on the question, “Is cobalt really needed?”
Cobalt is used as a cathode in battery technology, and out of all cathode materials available, it has the highest cost both fiscally and politically. Current consensus on battery technology says that without cobalt, the structural integrity and cycle life in batteries is compromised, as described in the interview. However, some recent scientific literature was cited by Kempaiah that indicated higher nickel content limited the impact of cobalt on batteries, possibly removing the need to use it at all. Nickel is more widely available across the globe, which keeps its cost down and mitigates the socioeconomic impacts often associated with resource mining operations. Overall, the discussion between Mitchell and Kempaiah indicated that Tesla can probably go cobalt-free soon, making it less vulnerable to the cobalt industry.
Finally, Tesla takes great care to educate its customers about proper battery maintenance, especially with regard to the negative impact of bad charging habits. Specifically, keeping an electric car battery charged at 100% for long periods degrades the battery very quickly, while keeping charging states within an optimal range will give it a long life. Tesla makes it a point to communicate to customers the importance of battery health on their overall ownership experience and value of their purchase.
When asked for his opinion by Mitchell, Kempaiah attributed the lack of education by other brands as a disconnect between engineering teams and marketing teams. While battery “best practices” are provided to EV customers by all manufacturers, the importance of communicating the true impact of bad charging habits may not be emphasized enough to be included as prominently as it should.
In summary, Tesla is constantly developing the technology in its vehicles, and its particular attention to its batteries looks to have given the company a significant advantage over its competitors. Perhaps other automakers will take a few tips from Tesla in the future, even if it’s as limited as improving communications with customers.
Watch Sean Mitchell’s full interview with Ravindra Kempaiah below:
Tesla Full Self-Driving has warranted a huge switch-up on an essential company strategy as the automaker is hoping to increase the take rate of the ADAS suite.
Unlike other automotive companies, Tesla has long been an outlier, as it has famously ditched a traditional advertising strategy in favor of organic buzz, natural word-of-mouth through its production innovation, and utilizing CEO Elon Musk’s huge social media presence to push its products.
Tesla has taken the money that it would normally spend on advertising and utilized it for R&D purposes. For a long time, it yielded great results, and ironically, Tesla saw benefits from other EV makers running ads.
Tesla counters jab at lack of advertising with perfect response
However, in recent years, Tesla has decided to adjust this strategy, showing a need to expand beyond its core enthusiast base, which is large, but does not span over millions and millions as it would need to fend off global EV competitors, which have become more well-rounded and a better threat to the company.
In 2024 and 2025, Tesla started utilizing ads to spread knowledge about its products. This is continuing, as Full Self-Driving ads are now being spotted on social media platforms, most notably, X, which is owned by Musk:

Interestingly, Tesla’s strategy on FSD advertising is present in Musk’s new compensation package, as the eleventh tranche describes a goal of achieving 10 million active paid FSD subscriptions.
Full Self-Driving is truly Tesla’s primary focus moving forward, although it could be argued that it also has a special type of dedication toward its Optimus robot project. However, FSD will ultimately become the basis for the Robotaxi, which will enable autonomous ride-sharing across the globe as it is permitted in more locations.
Tesla has been adjusting its advertising strategy over the past couple of years, and it seems it is focused on more ways to spread awareness about its products. It will be interesting to see if the company will expand its spending even further, as it has yet to put on a commercial during live television.
We wouldn’t put it out of the question, at least not yet.
Tesla was nice enough to hook us up with the new Model Y “Standard” trim for a few days, and while we’ll be sure to fill you in on the full experience in the coming days, there are a lot of differences we noticed right off the bat, which make the ownership experience different from the “Premium” configuration level.
I purchased a Model Y Long Range All-Wheel-Drive back in August and took delivery just two weeks later. Through the first three months of owning my car, I’ve come to love so many things about the Tesla experience.
I traded my ICE vehicle for a Tesla Model Y: here’s how it went
However, I was interested in experiencing the affordable trim and seeing whether I would miss any of the voided features of the “Premium” Model Y.
Through the first 24 hours, here are my first impressions of the Model Y Standard as a Premium trim level owner:
Overall Aesthetic
The lack of a light bar is not something that is a dealbreaker. In fact, I would argue that the Model Y Standard’s more traditional headlight design is just as pleasing from an aesthetic standpoint.
The car is great looking from top to bottom; there are not a substantial number of differences besides the lack of a lightbar on both the front and the back of the car.
Overall, it is a very sleek vehicle, but the major changes are obviously with the interior.
Interior Changes
This is where the big differences are, and some of the things I’ve gotten used to in the Premium are not included. If I didn’t have a Premium Model Y already, I’m not sure I’d miss some of the things that are not present in the Standard trim, but I believe I’d get annoyed with it.
First impressions:
✅ Interior is excellent. I definitely miss the additional storage already that is available in my Premium. I could definitely get over it though
✅ Noticeable step down in sound system. Long Time by Boston absolutely cranks in the Premium; it’s still very… https://t.co/JNWvxTd8p1

Storage
The Premium has a large storage compartment between the cupholders and the wireless charger, which is not present in the Standard trim. Instead, it is more like the Cybertruck, as there is a pass-through and floor storage.
I think that the pass-through is nice, but the additional storage is something I take advantage of, especially as someone who films Full Self-Driving videos, which requires hauling mounts, GoPros, and other accessories.
The sleekness of the Premium trim is also something I prefer; I really enjoy having the ability to close those compartments and cover the cupholders.
Obviously, this is a really trivial issue and not something that is substantially impactful from an ownership experience. If I weren’t already an owner, I am not sure I’d even have something to complain about.
Material Differences
The Premium trim seats are completely Vegan Leather, which I really do like, even as someone who doesn’t really love leather seats due to their temperature dependency.
The Standard trim features a Textile and Vegan hybrid, which has half of the seat a different material than the other.
The material is very similar to what I had in my previous car, a Bronco Sport. It was very durable, easy to clean, dried quickly, and hid a lot of things that leather does not, like oils from your skin, which constantly require attention to keep your interior looking fresh.
The wireless charger is also a different material, as the Premium features an Alcantara material on that. The Standard has a rubberized and textured backing, which looks good, too. They’re both more than suitable.
Other Missing Features
The Standard lacks a few minor things, most noticeably is the ambient lighting. The biggest change, however, and something I really miss, is the glass roof.
A lot of people told me that when I got my Model Y, I wouldn’t even notice the glass roof after a few weeks. That could not be further from the truth. I look out of it all the time, and it’s one of my family’s favorite parts of the car.
My Fiancè and I really love parking and watching Netflix when we pick food up, especially when it’s raining, because the glass roof gives such a great view.
We also loved it as Fall arrived, because it was great to look at the foliage.
Buy the Tesla.
Enjoy the glass roof. pic.twitter.com/r2GDyOEEWu

Bigger Differences
There are also a handful of very noticeable differences from the overall cabin experience, especially with the sound system.
Much Weaker Sound System
The Model Y Standard has just 7 speakers and 1 amp, with no subwoofer. This is a significant step down from the 13-15 speakers in the Premium Long Range AWD Model Y, the 2 amps it comes with, and 1 subwoofer in the trunk.
I usually like to listen to Long Time by Boston to test out a sound system, and it was noticeably weaker in the Standard. It was missing a big portion of the umph that is provided by the Premium’s sound system.
Cabin Noise
It feels like the Cabin Noise is definitely more noticeable in the Standard, which is something I really love about my Model Y. It is able to dampen so much road noise from louder cars, and I don’t feel as if it is very quiet in the Standard.
This is perhaps the biggest make-or-break for me with this car. I truly have been spoiled by how quiet the cabin is in the Premium, and it’s due to the lack of acoustic-lined glass in the Standard.
I will be doing a more in-depth review of the Model Y Standard, especially with ride quality, later this week.

Tesla takes a step towards removal of Robotaxi service’s safety drivers
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers.
Tesla appears to be preparing for the eventual removal of its Robotaxi service’s safety drivers.
This was hinted at in a recent de-compile of the Robotaxi App’s version 25.11.5, which was shared on social media platform X.
In-cabin analytics
As per Tesla software tracker @Tesla_App_iOS, the latest update to the Robotaxi app featured several improvements. These include Live Screen Sharing, as well as a feature that would allow Tesla to access video and audio inside the vehicle.
According to the software tracker, a new prompt has been added to the Robotaxi App that requests user consent for enhanced in-cabin data sharing, which comprise Cabin Camera Analytics and Sound Detection Analytics. Once accepted, Tesla would be able to retrieve video and audio data from the Robotaxi’s cabin.
Video and audio sharing
A screenshot posted by the software tracker on X showed that Cabin Camera Analytics is used to improve the intelligence of features like request support. Tesla has not explained exactly how the feature will be implemented, though this might mean that the in-cabin camera may be used to view and analyze the status of passengers when remote agents are contacted.
Sound Detection Analytics is expected to be used to improve the intelligence of features like siren recognition. This suggests that Robotaxis will always be actively listening for emergency vehicle sirens to improve how the system responds to them. Tesla, however, also maintained that data collected by Robotaxis will be anonymous. In-cabin data will not be linked to users unless they are needed for a safety event or a support request.
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers. With Tesla able to access video and audio feeds from Robotaxis, after all, users can get assistance even if they are alone in the driverless vehicle.
