A newly published patent from Tesla aims to bring the company’s idea for a one-million mile battery to life by using numerous electrolyte additives to increase the longevity and performance of its lithium-ion cells.
Tesla submitted the patent for “Dioxazolones and Nitrile Sulfites as Electrolyte Additives for Lithium-Ion Batteries” in August 2018. The patent is focused on improving the company’s rechargeable battery systems by adjusting the cells’ chemistry.
The patent claims that the addition of electrolyte additives, like lithium salt, can drastically improve the longevity and performance of battery systems when combined with a nonaqueous solution. A nonaqueous solution does not include water as the solvent, but rather another liquid.
The patent states:
Electrolyte additives have been shown to be operative and increase the lifetime and performance of Li-ion-based batteries… To further progress the adoption of electric vehicles and grid energy storage applications, it is desirable to develop lithium-ion cell chemistries that offer longer lifetimes at high temperatures and high cell voltages, without significantly increasing cost. The introduction of sacrificial electrolyte additives on the order of a few weight percent is a practical method to form protective solid-electrolyte interphase (SEI) layers that limit electrolyte decomposition during cell storage and operation. In recent years, significant efforts have yielded a large number of such additives that may be used to improve cell performance for various applications. Examples are vinylene carbonate (VC), fluoroethylene carbonate (FEC), prop-l-ene-l,3-sultone (PES), ethylene sulfate (1, 3, 2-dioxathiolane-2, 2-dioxide, DTD), and lithium difluorophosphate (LFO)
Tesla recognizes that increased temperatures are detrimental to the lifespan of a battery system. In a previous patent, Tesla outlined a cooling system that could lead to longer-lasting energy storage systems. While heat is unavoidable as it is a key player in the use of lithium-ion batteries, especially when owners of Tesla vehicles are operating in performance modes, engineers realize the solvents and solutions could be a way to improve performance and lifespan without significantly increasing cost.
In a way, a good part of Tesla’s lead in the electric car industry lies in the company’s batteries, or more specifically, its cell chemistry. It is these factors that allow Tesla to maximize its vehicles’ battery packs, and a key reason why the Model S Long Range is able to travel 373 miles on one charge with a 100 kWh battery, and why the Porsche Taycan can only go 201 miles per charge on a pack that’s nearly as large. This patent confirms that Tesla continues to work on improving its batteries, allowing the company to maintain or even increase its lead in the EV segment.
At Tesla’s Autonomy Day in April 2019, Elon Musk promised owners that the company would soon power its vehicles for upwards of one million miles over the span of the vehicle’s life. While the claim seemed enthusiastic and somewhat unrealistic, critics soon realized Tesla may be closer to this than many think. In September, a team of researchers led by Jeff Dahn at Dalhousie University published a research paper that claimed they had developed a lithium-ion battery capable of one million miles of driving, or 20 years of use in an energy-storage system.
Tesla’s battery technology continues to advance thanks to developments from its engineers. It appears Tesla is aiming to create a line of products that will last decades. In terms of automobiles, it would be groundbreaking to have a car that could run for 20 or 30 years with relatively no annual maintenance. Convenience, performance, and longevity are three things Tesla’s products are aimed toward, and the patent for an advanced and more affordable battery system thanks to an electrolyte solvent could alleviate any concerns some owners may have.

Tesla Semi’s latest adoptee will likely encourage more of the same
Public visibility matters. When shoppers see a trusted name like Ralph’s running clean, high-tech trucks on public roads, skepticism fades. Competitors such as Albertsons, which pre-ordered Semis years ago, and other chains chasing ESG targets now have proof that electric autonomy works in real-world grocery fleets.
The latest adoptee of the Tesla Semi will likely encourage more businesses in the same realm to adopt the all-electric Class 8 truck, as a new company utilizing the Semi has been spotted in Southern California.
A sleek, futuristic Tesla Semi truck branded for Ralph’s Supermarkets was spotted cruising a Los Angeles highway in a viral 13-second dashcam video posted March 2, by X user ChargePozitive.

The timing could not be better for sustainable logistics. Traditional trucking accounts for a massive share of retail emissions, but Tesla’s Semi slashes fuel and maintenance costs while leveraging full autonomy to ease driver shortages and improve safety.
Tesla’s expanding Megacharger network, including new sites along major freight corridors and partnerships like the recently-announced one with Pilot Travel Centers, is removing range anxiety and making nationwide scaling realistic. There’s still a long way to go, but things are moving in the right direction.

PepsiCo’s successful pilots already demonstrated viability, and Ralph’s sighting adds retail credibility.
As Tesla ramps high-volume Semi production through 2026, this isn’t an isolated curiosity. Instead, it’s a catalyst. More grocers adopting the platform will accelerate industry-wide decarbonization, cut operating expenses, and deliver tangible environmental wins.
The future of sustainable supply chains is already on the highway, and Ralph’s just made it impossible to ignore.
Moving forward, Tesla hopes to expand the Semi program into other regions, including Europe, which CEO Elon Musk recently said is a total possibility next year.

Tesla ramps Cybercab test manufacturing ahead of mass production
Tesla still has plans for volume production, which remains between four and eight weeks away, aligning with Musk’s statements that early ramps would be deliberately measured given the Cybercab’s novel architecture and full reliance on Tesla’s vision-based Full Self-Driving technology.
Tesla is seemingly ramping Cybercab test manufacturing ahead of mass production, which is scheduled to begin next month, the company said.
At Tesla’s Gigafactory Texas, production of the Cybercab, the company’s groundbreaking purpose-built Robotaxi vehicle, is accelerating markedly. Drone footage from Joe Tegtmeyer captured striking aerial footage today, revealing what appears to be the largest public sighting of Cyebrcabs to date.
A total of 25 units were observed by Tegtmeyer across the Gigafactory Texas property, marking a clear step-up in testing and validation activities as Tesla prepares for a broader output.
Tesla Cybercab production begins: The end of car ownership as we know it?
In the footage, 14 metallic gold Cybercabs were parked in a tight formation outside the factory exit, showcasing their sleek, autonomous-only design with no steering wheels, pedals, or traditional controls. Another 9 units sat at the crash testing facility, likely undergoing structural and safety validations, while two more appeared at the west end-of-line area for final checks.
Big day for Cybercab at Giga Texas today! Actually, yesterday to kick off March, the production line went into a higher volume & today we see 25 at three main locations, and there were several others I observed driving around too!
I think this may be the largest single grouping… pic.twitter.com/HZDMNv57lJ

Tegtmeyer noted additional Cybercabs driving around the complex, hinting at active movement and real-world testing beyond static parking.
This surge follows the first production Cybercab rolling off the line in mid-February 2026, several weeks ahead of the originally anticipated April start.
That milestone, celebrated by Tesla employees and confirmed by CEO Elon Musk, kicked off low-volume builds on the dedicated “unboxed” manufacturing line, a modular process designed to slash costs, reduce factory footprint, and enable faster assembly compared to conventional methods.
Industry observers interpret the jump to dozens of visible units in early March as evidence that Tesla has transitioned into higher-volume test manufacturing.
Tesla still has plans for volume production, which remains between four and eight weeks away, aligning with Musk’s statements that early ramps would be deliberately measured given the Cybercab’s novel architecture and full reliance on Tesla’s vision-based Full Self-Driving technology.
The Cybercab, envisioned as a sub-$30,000 autonomous two-seater for robotaxi fleets, represents Tesla’s bold pivot toward scalable autonomy and robotics.
Tesla fans and enthusiasts on X praised the imagery, with many expressing excitement over the visible progress toward deployment. While challenges remain, including software maturity, regulatory hurdles, and supply chain scaling, the increased factory activity underscores Tesla’s momentum in turning the Cybercab vision into reality.
As Giga Texas continues expanding and refining the manufacturing process of the Cybercab, the coming months will prove to be a pivotal time in determining how quickly this revolutionary vehicle reaches roads in the U.S. and internationally.

SpaceX to launch Starlink V2 satellites on Starship starting 2027
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls.
SpaceX is looking to start launching its next-generation Starlink V2 satellites in mid-2027 using Starship.
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls during remarks at Mobile World Congress (MWC) in Barcelona, Spain.
“With Starship, we’ll be able to deploy the constellation very quickly,” Nicolls stated. “Our goal is to deploy a constellation capable of providing global and contiguous coverage within six months, and that’s roughly 1,200 satellites.”
Nicolls added that once Starship is operational, it will be capable of launching approximately 50 of the larger, more powerful Starlink satellites at a time, as noted in a Bloomberg News report.
The initial deployment of roughly 1,200 next-generation satellites is intended to establish global and contiguous coverage. After that phase, SpaceX plans to continue expanding the system to reach “truly global coverage, including the polar regions,” Nicolls said.
Currently, all Starlink satellites are launched on SpaceX’s Falcon 9 rocket. The next-generation fleet will rely on Starship, which remains in development following a series of test flights in 2025. SpaceX is targeting its next Starship test flight, featuring an upgraded version of the rocket, as soon as this month.
Starlink is currently the largest satellite network in orbit, with nearly 10,000 satellites deployed. Bloomberg Intelligence estimates the business could generate approximately $9 billion in revenue for SpaceX in 2026.
Nicolls also confirmed that SpaceX is rebranding its direct-to-cell service as Starlink Mobile.
The service currently operates with 650 satellites capable of connecting directly to smartphones and has approximately 10 million monthly active users. SpaceX expects that figure to exceed 25 million monthly active users by the end of 2026.
