Tesla’s 1 million-mile battery takes a step forward with new electrode patent
A newly released patent from Tesla has teased what appears to be a step towards Elon Musk’s one-million-mile battery target. The patent describes a new lithiation process for battery cells, which has the potential to improve the quality of cells and possibly even save on costs.
Tesla has submitted a patent titled “Method for Synthesizing Nickel-Cobalt-Aluminum Electrodes.” The document outlines a new electrode synthesizing method that could be used for battery cell production. The proposed application defines an efficient heating process for Nickel-Cobalt-Aluminum (NCA) electrodes. According to the document, previous heating methods at times cause the formation of a lithium substrate known as L15AIO4, which is an impurity. Lowering the amount of lithium within a battery reduces the presence of the contamination, but also leads to “materials with inferior electrochemical properties.”
As noted in the patent, batteries would heat to a temperature high enough to allow for single crystal growth. The revised ratio of lithium to other metals would limit the formation of impurities during the first heating process. Then, the battery would be heated a second time at a temperature lower than the first heating cycle. Researchers involved in the patent noted that this process helped develop an impurity-free single crystal NCA that allowed battery cells to achieve over 4,000 charge cycles.
The patent outlines the heating process:
“Methods disclosed herein include a first lithiation step, wherein a lithium and an other metal component are present in a first lithium/other metal ratio of less than 1.0 and are sintered at a temperature between 800 and 950°C for a time period between 1 and 24 hours to obtain a first lithiated material. The method further includes a second lithiation step, wherein a lithium and a other metal component are present in a second lithium/other metal ratio and further wherein the first lithiated electrode material is sintered with additional LiOHTLO at between 650 and 760°C for a time period between 1 and 24 hours to obtain a second lithiated material.”
In summary, the use of NCA electrodes in batteries would allow for single-crystal materials to present themselves without impurities. The lack of contaminants could lead to an increased lifespan of the cells altogether, helping Tesla take a giant leap forward in its quest to produce a one-million-mile battery for its vehicles.
Interestingly enough, one of the listed names on the patent is battery expert and researcher Jeff Dahn, who has worked with Tesla in the past. Tesla summoned the help of Dahn, who leads a team of researchers at Canada’s Dalhousie University, to help the electric car maker improve its batteries. Dahn’s research has helped Tesla’s development of high-quality battery cells by inventing new electrode combinations, like the one described in this patent, and electrolyte solutions aimed at further increasing battery life.
Tesla’s batteries are always in a state of improvement, and over the years, the cells that the company utilizes for its vehicles and energy storage systems have gotten more energy-dense. Economies of scale that is made possible with facilities such as Gigafactory Nevada have also gone a long way towards helping Tesla near the $100 per kWh mark, a level that is widely considered the point where electric vehicles could achieve price parity with their internal combustion-powered counterparts.
Apart from its battery patents, Tesla has also been busy acquiring several battery companies. Among these are Maxwell Technologies and Hibar Systems, both of which were developing technologies that would allow for better battery quality and more efficient production costs. Relatively simple developments such as those described in Tesla’s recent patent help this cause too, especially since every little bit of optimization helps.
Tesla’s development of its battery technology could lead to its vehicles lasting 20 to 30 years, far longer than petrol-powered cars. It appears the company is planning to create a product line that could stay with owners for extended periods with relatively no annual maintenance. And that, together with price parity, can very well be the catalyst for society’s acceleration towards sustainability.

Tesla is building a massive Cybercab car wash in Las Vegas
Tesla quietly filed plans to build the Cybercab car wash, and on May 12, the company submitted a permit to begin renovating the “Tesla Center Cybercab Phase 2 Car Wash,” documents show.
Tesla is beginning to construct what will be an incredibly unique project, as it is now building a 36,000-square-foot car wash just for the Cybercab in Clark County, Nevada, near Las Vegas.
Tesla quietly filed plans to build the Cybercab car wash, and on May 12, the company submitted a permit to begin renovating the “Tesla Center Cybercab Phase 2 Car Wash,” documents show.
This is not just some ordinary car wash. Instead, it’s a dedicated, high-tech maintenance hub built specifically for Tesla’s ride-hailing vehicle and the many units that will be in the fleet.
According to the permit documents, which were first spotted by MarcoRP, a Supercharger observer on X, the work involves upgrading and updating the interior and exterior of an existing 36,000-square-foot facility. Crews will construct a full car-wash enclosure, relocate tire-service equipment, and install new power raceways.
Tesla has reportedly submitted plans for a carwash dedicated for Robotaxis in Las Vegas. The permit, filed with Clark County on May 12th, describes “Tesla Center Cybercab Phase 2 Car Wash.”

Every camera on a Tesla Cybercab must stay clean, and without a human driver to perform manual maintenance on the vehicle, this Cybercab-specific car wash will be crucial in keeping the fleet operational, safe, and effective.
Tesla has spent years perfecting unsupervised FSD, and the Cybercab – unveiled last year as a driverless, two-seater purpose-built for ride-hailing – is the physical embodiment of that vision. Industry skeptics have long questioned how a massive Robotaxi network could scale without drivers handling basic upkeep.
Tesla just answered them with a permit filing. Sources close to the project suggest this could be the first of several such hubs, with whispers of similar plans already surfacing in Texas.
A purpose-built Robotaxi wash station means fleets can cycle vehicles through cleaning, charging, and minor servicing at lightning speed with almost no human intervention. Optimus robots could eventually handle the physical work, turning the entire operation into a lights-out, 24/7 machine.
Las Vegas, with its endless tourist traffic and wide-open roads, is the perfect proving ground. Imagine stepping out of a gleaming Cybercab after a night on the Strip, knowing the same vehicle will be sparkling clean and ready for the next rider within minutes.

Critics who claimed Robotaxis would get filthy and unreliable now look shortsighted. However, it will be interesting to see how many of these types of facilities the company establishes, especially as it plans for the Robotaxi fleet to be available everywhere.
If the permit moves forward as expected, Las Vegas could witness the first large-scale, fully autonomous taxi operation complete with its own cleaning infrastructure. As soon as Tesla solves wireless charging, we’re looking at a very capable and potentially fully autonomous ride-sharing business from A to Z.

Tesla puts Giga Berlin in Plaid Mode with new massive investment
The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.
Tesla is pushing forward with significant upgrades at its Gigafactory Berlin-Brandenburg in Grünheide, Germany, signaling renewed confidence in its European operations despite past market challenges.
The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.
In April, plant manager André Thierig announced a 20 percent increase in Model Y production starting in July, following a record Q1 output of more than 61,000 vehicles. To support the ramp-up, Tesla plans to hire approximately 1,000 new employees beginning in May and convert 500 temporary workers to permanent positions.
The move is expected to lift weekly production significantly, addressing rebounding demand in Europe after a challenging 2025.
Today, we announced a $ 250m investment for our Giga Berlin Cell factory. This will enable 18GWh of annual 4680 cell production and create more than 1500 new jobs. Good news during challenging times for the German industry. pic.twitter.com/ou4SWMfWh9

The expansion builds on earlier progress. In 2025, Tesla secured partial approvals to add roughly 2 million square feet of factory space, raising potential annual vehicle capacity from around 500,000 toward 800,000 units, with longer-term ambitions approaching one million vehicles per year. Logistical improvements, new infrastructure, and battery-related facilities are already underway on company-owned land.
Battery production is the latest major focus. On May 12, Thierig revealed an additional $250 million investment in the on-site cell factory. This more than doubles the planned 4680 battery cell capacity to 18 gigawatt-hours annually—up from the 8 GWh target set in December 2025—while creating over 1,500 new battery-related jobs.
Total cell investments at the site now exceed previous figures, bringing the factory closer to full vertical integration: cells, packs, and vehicles produced under one roof. Tesla describes this as unique in Europe and a step toward stronger supply chain resilience.
The plans come amid regulatory and community hurdles. Earlier expansion proposals faced protests over environmental concerns and water usage, leading to phased approvals beginning in 2024. Tesla has navigated these by emphasizing sustainable practices and economic benefits, including thousands of local jobs in Brandenburg.
With nearly 12,000 employees already on site and production steadily climbing, Gigafactory Berlin is poised for growth. The combined vehicle and battery expansions position the plant as a key hub for Tesla’s European ambitions, potentially making it one of the continent’s largest manufacturing complexes if local support continues.
As EV demand recovers, these investments underscore Tesla’s commitment to scaling efficiently in Germany while addressing regional supply chain needs.

Honda gives up on all-EV future: ‘Not realistic’
Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.
Honda has given up on a previous plan to completely changeover to EVs by 2040, a new report states. The company’s CEO, Toshihiro Mibe, said that the idea is “not realistic.”
Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.
Mibe said (via Motor1):
“Because of the uncertainty in the business environment and also the customer demand, is changing beyond our expectation and, therefore, we have judged that it’ll be difficult to achieve. That ratio [100-percent electric in 2040] is not realistic as of now. We have withdrawn this target.”
Instead of going all-electric, Honda still wants to oblige by its hopes to be net carbon neutral by 2050. It will do this by focusing on those popular hybrid powertrains, planning to launch 15 of them by March 2030.
Honda will invest 4.4 trillion yen, or almost $28 billion, to build hybrid powertrains built around four and six-cylinder gas engines.
There are so many companies abandoning their all-electric ambitions or even slowing their roll on building them so quickly. Ford, General Motors, Mercedes, and Nissan have all retreated from aggressive EV targets by either cancelling, delaying, or pausing the development of electric models.
Hyundai’s 2030 targets rely on mixed offerings of electric, hybrid & hydrogen vehicles
Early-decade pledges from multiple brands proved overly ambitious as infrastructure lags, battery costs remain high in some markets, and many buyers prefer hybrids for their convenience and range. Toyota has long championed hybrids, while others have quietly extended internal-combustion timelines.
For Honda—historically known for reliable gasoline engines—this shift leverages its core strengths while buying time to refine electric technology. Whether the hybrid-heavy strategy will protect market share in an increasingly competitive landscape remains to be seen, but one thing is clear: the gas engine is far from dead at Honda, unfortunately.
