Tesla’s battery research team in Canada, led by Jeff Dahn, is on the verge of proving revolutionary battery density through a new, next-gen battery cell. The team released its findings in a new paper, which shows how to combat anode-free cell failure through electrolyte solutions.

The paper is titled “Diagnosing and correcting anode-free cell failure via electrolyte and morphological analysis.” Dahn and his team of researchers at Dalhousie University show that some of the anode-free battery cells that are used tend to store more energy per volume than traditional lithium-ion cells. This is crucial in increasing the range availability of electric cars.

The anode-free batteries also are lighter than traditional cells, according to Hansen Wang, a battery researcher at Stanford University.

“The idea is to only use lithium on the cathode side to reduce weight,” Wang said in an interview with the prestigious school in Northern California.

However, with the increased energy storage capacity, some downsides become present. One fallback is the cells “tend to experience rapid capacity loss and short cycle life,” the paper’s abstract says on Nature. There are also safety issues with anode-free cells that pertain to the metallic lithium that is present within.

Dahn and his team stated that the anode-free cells are capable of an extended lifespan when a dual-salt carbonate electrolyte solution is used to combat the effects of degradation.

The team states:

“Recently, we demonstrated long-lifetime anode-free cells using a dual-salt carbonate electrolyte. Here we characterize the degradation of anode-free cells with this lean (2.6 g Ah−1) liquid electrolyte. We observe deterioration of the pristine lithium morphology using scanning electron microscopy and X-ray tomography, and diagnose the cause as electrolyte degradation and depletion using nuclear magnetic resonance spectroscopy and ultrasonic transmission mapping. For the safety characterization tests, we measure the cell temperature during nail penetration.”

When Dahn’s team utilized the dual-salt carbonate electrolyte solution in battery cells, it showed that an inactive mix of dead lithium forms large lithium columns in the cell. This creates an exemplary lithium morphology within the cell, which could solve the issues with a short lifespan.

In the past, Tesla patented an electrolyte solution that could be added to lithium-ion batteries to extend a cell’s lifespan.

The optimized electrolyte successfully extended the lifetime of anode-free cells to 200 total cycles, which is a significant improvement from other findings. For example, the previously mentioned experiment at Stanford University was performed in June 2020. This experiment showed that anode-free battery cells ran 100 cycles before the capacity dropped to 80 percent.

The improvements in battery cell lifespan will eventually lead to longer-lasting cells in electric vehicles. Tesla has been working toward a million-mile capable battery cell for an extended period, which could be unveiled at the company’s Battery Day event on September 22.

Energy density is ultimately the key to more extended range, but there is a fine line between jeopardizing lifespan for more miles per charge. Ultimately, the research with Dahn’s team will continue, and it is a significant advancement in terms of what past research has shown.

During Elon Musk’s interview at the Qatar Economic Forum, he announced that Neuralink aims to implant its Blindsight brain-to-computer interface (BCI) device in a human patient by late 2025 or early 2026.

Blindsight focuses on restoring vision. A few years ago, Musk mentioned that Neuralink’s BCI devices would restore vision for people, even those born blind.

“The first two applications we’re going to aim for in humans are restoring vision, and I think this is notable in that even if someone has never had vision ever, like they were born blind, we believe we can still restore vision. The visual part of the cortex is still there. Even if they’ve never seen before, we’re confident they could see,” Musk said during Neuralink’s Show & Tell in 2022. 

Musk said Blindsight could be implanted into a human patient in the United Arab Emirates (UAE). Neuralink plans to partner with the Cleveland Clinic Abu Dhabi to implant the first human patient with Blindsight.

Elon Musk’s neurotechnology company is partnering with the Cleveland Clinic Abu Dhabi to conduct the first clinical trial of the UAE-PRIME study. Like Neuralink’s PRIME study in the United States, UAE-PRIME will focus on human patients with motor and speech impairments.

Neuralink received Food and Drug Administration (FDA) approval to conduct the PRIME and CONVOY studies in the United States. PRIME tests the capabilities of the company’s Link implant to restore or enable motor and speech in participants. Meanwhile, the CONVOY study explores Link’s ability to control assistive robotic devices. Neuralink already has an assistive robotic arm called ARA that could expand patients’ autonomy beyond smart devices.

Blindsight would probably require a separate study from PRIME and CONVOY. As such, Neuralink might need FDA approval in the United States to start human trials for Blindsight. However, Blindsight already received a “breakthrough device” designation from the US FDA.

In April 2025, Neuralink opened its patient registry to participants worldwide. The neurotechnology company has already implanted its Link BCI device into five patients. Earlier this year, Neuralink welcomed one of its first PRIME study participants as the first patient in its CONVOY study.

Elon Musk just revealed more about Tesla’s June Robotaxi launch

Tesla CEO Elon Musk gave more information about the Robotaxi launch in Austin set for June.

Tesla CEO Elon Musk just revealed more details about the company’s June Robotaxi launch, which will kick off in Austin.

As of right now, Tesla is still set to push out the first Robotaxi rides in Austin, Texas, in early June. These vehicles will be in short supply at first, as Musk says the company is purposely rolling out the fleet in a slow and controlled fashion to prioritize safety. There will be ten vehicles in the Robotaxi fleet to start.

Tesla Robotaxi deemed a total failure by media — even though it hasn’t been released

However, in an interview with CNBC on Tuesday afternoon, Musk also revealed some other new details, including where in Austin the vehicles will be able to go, how many Robotaxis we could see on public roads within a few months, and other information regarding Tesla’s Full Self-Driving suite.

A Controlled Rollout

Tesla has maintained for a few months now that the Robotaxi fleet will be comprised of between 10 and 20 Model Y vehicles in Austin.

The Cybercab, which was unveiled by the company last October, will not be available initially, as those cars will likely be produced in 2026.

Musk said during the CNBC interview that Tesla is doing a low-yield trial at first to initiate a safety-first mentality. It is important for Tesla to launch the Robotaxi fleet in a small manner to keep things in check, at least at first.

As confidence builds and the accuracy of the fleet is ensured, more vehicles will be added to the fleet.

Musk believes there will be 1,000 Robotaxis on the road “in a few months.”

Geofenced to Certain Austin Areas

Tesla will be launching the Robotaxi program in a geofenced fashion that gives the company the ability to control where it goes. Musk says that the areas the Robotaxis will be able to travel to are among the safest neighborhoods and areas in Austin.

This is yet another safety protocol that will ensure the initial riders are not put in dangerous neighborhoods.

Some might be disappointed to hear this because of Tesla’s spoken confidence regarding Robotaxi, but the initial rollout does need to be controlled for safety reasons. An accident or incident of any kind that would put riders’ lives in danger would be catastrophic.

No Driver, No Problem

As the company has rolled out an employee-only version of the Robotaxi program in Austin and the San Francisco Bay Area, some wondered whether the rides would be driverless, as these initial trials for Tesla workers were not. Employee rides featured a human in the driver’s seat to ensure safety.

Tesla says it has launched ride-hailing Robotaxi teaser to employees only

The company did not report whether there were any interventions or not, but it did state that the vehicles traveled over 15,000 miles through 1,500 trips.

Musk confirmed during the interview that there will be no driver in the vehicle when the Robotaxi program launches in June. This will be groundbreaking as it will be the first time that Tesla vehicles will operate on public roads without anyone in the driver’s seat.

Full Self-Driving Licensing

For more than a year, Tesla has indicated that it is in talks with another major automaker regarding the licensing of Full Self-Driving. Many speculated that the company was Ford, but neither it nor Tesla confirmed this.

Musk said today that Tesla has been in touch with “a number of automakers” that have inquired about licensing FSD. Tesla has yet to sign any deal to do so.

Elon Musk on Tesla vehicle sales: “We see no problem with demand”

“The sales numbers at this point are strong, and we see no problem with demand,” Musk said.

During a rather testy interview with Bloomberg’s Mishal Husain at the Qatar Economic Forum, Elon Musk stated that the demand for Tesla’s vehicles is still strong. Musk also stated that the issues that Tesla faced earlier his year have already turned around.

Already Turned Around

Tesla sales saw notable drops in the past months, particularly in Europe, where several countries saw drastically fewer Tesla sales year-over-year. Tesla stated in its Q1 2025 vehicle delivery report that the declines were largely due to the company’s changeover to the new Model Y, but media reports nevertheless placed the blame on Musk’s politics and his work with the Trump administration’s Department of Government Efficiency (DOGE).

It was then no surprise that Bloomberg’s Husain pointed out Tesla’s low sales in Europe this April during the interview. When questioned about the matter, Musk stated that things have “already turned around.” Musk also noted that while Tesla sales are down in Europe so far, this is true for numerous other carmakers in the region.

No Problem With Demand

When asked for evidence to back up his claims, Musk stated that Europe is indeed Tesla’s weakest market, but the company remains “strong everywhere else.” He also admitted that while Tesla has “lost some sales from the left,” the company also “gained some from the right.” Musk highlighted the fact that Tesla stock, which is partly affected by analysts with insider information, is trading at near all-time highs.

“The sales numbers at this point are strong, and we see no problem with demand. You can just look at the stock price. If you want the best insider information, the stock market analysts have that, and our stock wouldn’t be trading near all-time highs if things weren’t in good shape. They’re fine. Don’t worry about it,” Musk said.
