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 expands Robotaxi in a way that was long anticipated

Instead, it has to do with the consumer base it offers Robotaxi to, because it has not offered it to everyone in the past.

Tesla has expanded Robotaxi in a way that was long anticipated, and it does not have to do with a new, larger geofence in a city where it already offered its partially autonomous ride-hailing suite, or a new city altogether.

Instead, it has to do with the consumer base it offers Robotaxi to, because it has not offered it to everyone in the past.

Tesla has taken a major step forward in its autonomous ride-hailing ambitions with the official launch of the Tesla Robotaxi app for Android users. Released on the Google Play Store on April 24. Titled simply “Tesla Robotaxi,” the app is now available to download directly from Tesla.

This rollout fulfills a long-anticipated expansion that opens the service to hundreds of millions of Android smartphone users who were previously unable to access it on iOS alone.

The app delivers a streamlined, driverless ride experience powered by Tesla’s automated driving technology.

Users sign in with a Tesla Account, view the current service area map within the app, enter a destination, and receive an estimated fare and arrival time before confirming the ride. When a Model Y from the Robotaxi fleet arrives, riders confirm the license plate, enter the vehicle, fasten their seatbelt, and tap “Start Ride” on either the app or the vehicle’s touchscreen.

During the trip, passengers have access to all the same controls that iOS users do, and can adjust climate settings, seat positions, and music while tracking progress on an in-app map. The interface also allows drop-off changes or support requests if needed. After the ride, users exit, close the doors, and submit feedback.

This Android availability directly broadens the rider base for Robotaxi in its initial service areas. Unfortunately, Android users are used to being subject to delayed launches of new features available to Tesla owners.

By removing the iOS-only barrier, Tesla instantly expands the addressable market, enabling far more people to summon and use the autonomous vehicles already operating on public roads.

The move is a foundational requirement for scaling ride volume and gathering the real-world data needed to refine the unsupervised Full Self-Driving system that powers every trip.

For the Robotaxi program itself, the launch signals steady operational progress. It prepares the service for higher utilization rates as the fleet grows and supports the transition from limited early deployments to a more robust network.

Tesla expands Unsupervised Robotaxi service to two new cities

Tesla has indicated that users outside current service areas can sign up at the company’s website for future notifications, pointing to a deliberate, phased geographic rollout.

Looking ahead, the company plans to incorporate Cybercab vehicles to increase fleet capacity and efficiency while continuing to expand service territories. With the Android app now live, Tesla has removed a key adoption hurdle and positioned Robotaxi for the next phase of growth in autonomous urban transportation.

The infrastructure is now in place to support significantly larger rider demand as production and deployment accelerate.

UPDATE: SpaceX’s Falcon Heavy that launched a Tesla into space is back on a mission

SpaceX Falcon Heavy returns after 18 months away to deliver a satellite that only it could carry.

UPDATE: 10:29 a.m. et: SpaceX is standing down from today’s Falcon Heavy launch of the ViaSat-3 F3 mission due to unfavorable weather. A new target date will be shared once confirmed.

After an 18-month absence, SpaceX’s Falcon Heavy is returning to mission on Monday morning when it’s scheduled to lift off from Launch Complex 39A at Kennedy Space Center at 10:21 a.m. EDT.

The mission is called ViaSat-3 F3, and the heavy satellite payload needs to reach geostationary orbit, sitting 22,236 miles above Earth where its speed matches the planet’s rotation. Getting a satellite that heavy to that altitude demands more thrust than a single-core Falcon 9 can deliver.

This marks the Falcon Heavy’s 12th flight overall since its debut in February 2018, and its first since NASA’s Europa Clipper mission in October 2024.

Arguably, the most exciting element for spectators will be watching the booster recoveries in action when the two side boosters, B1072 and B1075, will attempt simultaneous landings at Landing Zone 2 and the newer Landing Zone 40 at Cape Canaveral Space Force Station, while the center core will be expended over the ocean.

SpaceX wins its first MARS contract but it comes with a catch

Following satellite deployment, expected roughly five hours after launch, ViaSat-3 F3 will spend several months traveling to its final orbital slot before undergoing in-orbit testing, with service entry expected by late summer 2026

As Teslarati reported, NASA awarded SpaceX a $175.7 million contract on April 16, 2026, to launch the ESA Rosalind Franklin Mars rover aboard a Falcon Heavy no earlier than late 2028, which would mark the first time SpaceX has ever sent a payload to Mars. That contract came on top of an already deep pipeline that includes the Roman Space Telescope, the Dragonfly Saturn mission, and multiple national security payloads.

SpaceX executed 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. With Starlink surpassing 10 million subscribers and an IPO targeting a $1.75 trillion valuation still ahead, Monday’s launch is one more data point in a company that has quietly become the backbone of both commercial and government space access worldwide.

Tesla launches solution to end Supercharger fights once and for all

Tesla is launching its solution to end Supercharger fights once and for all, eliminating any confusion on who is to charge next at a congested location.

Last year, a notable incident at a Tesla Supercharger led to a fight, and it all stemmed from a disagreement over who arrived at the location first.

Congestion at Tesla Superchargers is a pretty infrequent occurrence for most of us, but there are more congested and popular areas where wait times can be extensive. An unfortunate growing pain of EV ownership is the plain fact that chargers are not as available as gas pumps, and there are, at times, lines to charge.

This can cause tensions to flare and people to get entitled when visiting Superchargers. Nobody wants to spend hours at a Supercharger, but now, there will be no more confusion when there is a queue, and that’s thanks to Tesla’s new Virtual Queue for Superchargers.

Tesla is finally starting to build out the Virtual Supercharger Queue, according to Not a Tesla App, but it still relies on drivers to make it work.

When a driver is near a Supercharger that is full, a message will pop up on the Tesla App, using the driver’s location to determine their eligibility to join the virtual queue.

The app states:

“While the app is closed, Tesla uses your location to notify you of accurate wait times at Superchargers when you arrive.”

Another message within the app states:

“There is a waitlist to charge. Are you sure you want to start a charging session now?”

This sounds as if it will require drivers to act appropriately and only plug in when the app prompts them to do so, by letting them know it is their turn.

The app will notify the driver of their position in the queue, as well as how many vehicles are ahead of them.

Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means

The company announced a while back that it would be working on a solution for this issue. Personally, I’ve only had to wait at a Supercharger for a charge on one occasion, and there was a line of between 3 and 10 cars during this singular occurrence.

There were no conflicts or arguments about who had arrived first, but there was some discussion between several drivers during my time there about who was to charge first. Throw a non-Tesla EV into the mix, one that can only charge at a pull-in spot, and that causes even more of a complication.
