Tesla battery researcher Jeff Dahn’s tests hint at li-ion cells breaking the 2M-mile barrier
Last year, the electric vehicle community’s attention was caught when Tesla battery researcher Jeff Dahn and his team published a paper revealing that quality lithium-ion batteries have the capability to last 1 million miles if used in EVs. A recent presentation from the respected battery pioneer has now revealed that these findings may actually be conservative, as the batteries that Dahn and his team have been testing are still going strong, and are now on track to pass the 2-million-mile mark.
Dahn’s updated findings were discussed in a recent video conference for energy storage and sustainable engineering. According to Dahn, the “million-mile” batteries that were referred to in the past year’s paper are now going towards 10,000 to 15,000 cycles. Considering that the million-mile cells were cycled 5,000 times, it is starting to become evident that the lithium-ion batteries that Dahn’s team have been testing have the potential capability to last 3.5 million km or over 2 million miles if used in an electric vehicle.
Remarkably, the lithium-ion cells that are being cycled by Dahn and his team have shown minimal degradation even at this point. With this in mind, there seems to be a good chance that even the study’s “2-million-mile” cells are capable of lasting even longer. Dahn notes that lithium-ion batteries have reached a point where it is becoming imperative to look into the further applications of advanced battery technology, such as vehicle-to-grid, or massive vehicles like airplanes and ferries.
As noted by the team in its 2019 paper, the lithium-ion batteries that it will be using are NMC532 pouch cells obtained from Li-FUN Technology in China. The NMC532 pouch cells are dry batteries as well, using no electrolytes. Interestingly enough, Tesla’s next-generation 4680 cells that the company revealed at Battery Day also utilize dry battery technology developed from the innovations of Maxwell Technologies, a company that the EV maker acquired.
Considering that the batteries which Dahn and his team are testing are just cells acquired from Li-FUN Technology in China, there seems to be a pretty good chance that Tesla’s next-generation 4680 cells could exhibit comparable or even superior performance when they are deployed to the company’s fleet of vehicles and energy storage units in the coming years. If these assumptions prove accurate, then Tesla’s next-generation cells may truly be a class above anything that is being used in the market today. Dahn, for his part, noted that Tesla’s battery strategy is sound.
“Tesla is just moving forward at the speed of light. They are upscaling their factories, they know they need Tera Watt Hours for both energy storage and vehicles, and it’s incredibly exciting times,” he said.

Starlink gets its latest airline adoptee for stable and reliable internet access
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.
Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.
The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.
Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:
“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”
Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.
Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.
This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.
Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:
“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”
Starlink recently crossed a massive milestone of over 10 million subscribers.

Tesla nears closure of Full Self-Driving purchasing option
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
Tesla is nearing the closure of its Full Self-Driving outright purchasing option, which will be removed on February 14, meaning Saturday will be the last time it can be bought as a non-subscription.
Tesla is aiming to move its Full Self-Driving suite to a subscription-only platform, a move that will enable people to only pay monthly for the semi-autonomous driving functionality.
The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.
It is currently priced at $8,000 for the outright option to use Full Self-Driving, a substantial decrease compared to the $15,000 it was priced at one time. For the monthly subscription, it is just $99 per month, but that price will change, likely increasing as things get more advanced.
Tesla is overhauling its Full Self-Driving subscription for easier access
We say it will likely increase because there is no indication of how Tesla will price FSD. There has been some speculation that Tesla could utilize a tiered system to price FSD, which would potentially allow owners to pick and choose a set of features that would be most ideal for them.
This would potentially introduce an even more affordable option for FSD use, but this is unconfirmed. The reason many say this could be an option for Tesla is the fact that if the price goes up further, the take rate, which is currently around 12 percent at its most recent estimate, could be lower.
Musk needs 10 million active Full Self-Driving subscriptions to unlock one of the tranches of his newest compensation package.
The move to a subscription-only platform has its positives and negatives, and owners have been more than vocal about these since Musk confirmed the move.
Positives
- Lower barrier to entry and higher potential adoption
- Financially better for many users
- Easier transfers and brand loyalty
- Predictable recurring revenue for Tesla
- Access to the latest features
Negatives
- Higher long-term cost for loyal/long-term owners
- No true “ownership” or permanence
- Risk of future price hikes or even deactivation
- Perceived as of less value
- Impact on resale and used market
Overall, there is a split among the Tesla community in terms of what they see as the “right” way to handle this. Tesla is likely to shed more details on what its plans for the subscription-only platform will be, including pricing, in the coming weeks.

Elon Musk’s Boring Company selected for Universal Orlando tunnel project
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe.
The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive.
As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project.
The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.
The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.
Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.
The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.
For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.
“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.
The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.
