Tesla in talks with Brazil-based startup to access lithium supply for EV batteries
Tesla is reportedly looking to strike a deal with Sigma Lithium Resources Group, a Brazilian startup company that can supply Tesla with lithium, a key ingredient of electric car batteries.
Sigma was granted a license to begin mining lithium by the Environmental Authority of the State of Minas Gerais, the Council of Environmental Policy on June 11, 2019. The license will allow Sigma to mine hard rock lithium, a crucial piece of automotive-grade lithium-ion batteries, for six-years, making the company an extremely valuable asset for automakers pursuing electric mobility.
It should be noted that Brazil was ranked No.7 among countries with the highest concentration of lithium. A large percentage of the metal, used primarily for the production of glass and batteries, is available in the Minas Gerais area.
Sigma has previously met with Tesla’s current lithium supplier, Ganfeng Lithium, a Chinese-based company that is currently the country’s largest supplier of the material. Tesla reportedly organized the meeting between both parties that unfortunately did not end in a deal. Sigma CEO Calvyn Gardner cited the Brazilian startup company could not meet the financial or production needs that Ganfeng requested.
“There’s a bunch of other things that they [Ganfeng] need, not just prices, but other demands which are a little more complicated that sort of restricts Sigma to almost supplying purely into China. It’s not really what we think we should be doing over the long term,” Gardner remarked at a mining conference in Brazil.
Gardner, who calls himself a “fan” of Tesla, was interested in purchasing a Model 3 for himself but ran into roadblocks as Tesla does not have a sales office in the South American country. After import taxes would have more than doubled the cost of the Model 3, he decided to hold off.
Striking a deal with Tesla would directly benefit both companies. Tesla currently uses Gigafactory partner Panasonic as its battery supplier but appears to be seeking to expand it lineup of partners, especially after the Japanese electronics conglomerate has cut its profit outlook due to China’s trade war with the US. Tesla’s acquisition of Maxwell Technologies, an ultracapacitor producer, also hinted at the electric car maker’s plans to pursue battery technology beyond its Panasonic partnership.

It would be beneficial for both Tesla and Sigma to strike a deal directly, with the Brazilian company shipping the lithium to the electric car maker. Unfortunately, this could only happen once makers of cathodes, another primary component of batteries, set up facilities in the United States.
Other large automakers that are bursting into the electric transportation market, such as Volkswagen and BMW, have held talks with Sigma already. Gardner, a graduate of the University of South Africa, is optimistic over the talks with both German automakers. “Having options to get lithium from other jurisdictions and that you can supply over the long term,” he said. “That’s what all of them are interested in and we think Sigma can do that.”
There is no shortage of money or optimism in the lithium mining industry. Sigma has recently received a $30 million loan from Japanese trading group Mitsui, according to Reuters. The money is planned to be used in building Sigma facilities, and will be repaid in a big way: a third of Sigma’s planned output of lithium from its Minas Gerais mining facility.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
