Tesla quietly revealed in its Q1 report that nearly half the vehicles it produced in the first quarter of 2022 were equipped with cobalt-free lithium iron phosphate (LFP) batteries. The news, however, was overshadowed in the news cycle, particularly by Tesla’s $19 billion revenue and CEO Elon Musk’s acquisition of social media platform Twitter.
LFP batteries are not a new innovation, but it has not been used as much in areas outside China. According to data from Benchmark Mineral Intelligence (BMI), only 3% of electric vehicle batteries in the United States and Canada and 6% in the European Union are iron-based. In China, however, LFP batteries command 44% of the EV market.
Tesla currently uses LFP batteries in its base vehicles, though Elon Musk has hinted that the EV company will be using more cobalt-free cells in more products. Considering the prolific nature of Tesla and its influence on the market, it would not be surprising if other EV makers also began exploring the option of using LFP batteries for their own cars.
Amusingly enough, by playing a notable part in LFP battery adoption, it appears that Elon Musk has effectively become an “iron man” of sorts.
According to a Reuters review of the EV market, Tesla is not alone in its support for LFP batteries. Over a dozen companies are reportedly considering building LFP battery cell plants in the United States and Europe in the next three years. And things will likely only pick up from there. Mujeeb Ijaz, the founder of US battery startup Our Next Energy, noted that LFP has a future in the EV industry.
“I think lithium iron phosphate has a new life. It has a clear and long-term advantage for the electric vehicle industry,” he said.
There was a reason why LFP batteries took this long to gain ground. While LFP cells use cheaper materials, and while they could be consistently charged fully without much degradation, they tend to be larger, heavier, and generally hold less energy than nickel-cobalt-manganese (NCM) cells. Thus, electric cars that use LFP batteries tend to have shorter range.
Tesla’s decision to use LFP batteries for its base vehicles could be considered a strategic move. Since the company is electively the undisputed leader in the electric vehicle sector, the roughly 150,000 cars it produced last quarter that were equipped with LFP batteries took a number of analysts and specialists by surprise. And similar to other innovations from the company, such as its use of megacasts, it appears that other carmakers will soon be following suit.
EV startup Fisker, for one, noted that it is planning on using LFP batteries for its lower-range SUVs. CEO Henrik Fisker noted that the company is in discussions with battery suppliers from the United States, Canada, or Mexico. Fisker noted that LFP batteries are perfect for vehicles that are used by city-dwellers.
“If I never leave Los Angeles, I never leave San Francisco, I never leave London … I think that’s where LFP comes in really well,” he said.
Audi CEO Markus Duesmann, in comments that were shared last March, also spoke highly of LFP cells’ potential. “It may well be that we will see LFP in a larger portion of the fleet in the medium term. After the war, a new situation will emerge; we will adapt to that and choose battery technologies and specifications accordingly,” he said.
Even BMW, which is arguably lagging in the electric vehicle race considering the pace of rivals such as Volkswagen and Daimler, is looking towards LFP batteries. Recent comments from BMW chief procurement officer Joachim Post indicated that the German automaker was analyzing the merits of iron-based cells. “We’re looking at different technologies to minimize the use of resources and also we’re looking at optimizing chemistry,” the executive said.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.
