Redwood CEO JB Straubel talks battery supply crisis, dubs tenure at Tesla as “amazing adventure”
During a recent interview with CNN anchor Julia Chatterley, Tesla co-founder and Redwood Materials CEO JB Straubel shared his thoughts about what he estimates is an upcoming electric vehicle battery supply crisis, his thoughts on the adoption of recycled batteries, and his long tenure with the Elon Musk-led EV maker.
With the world’s most prominent automakers embracing electric vehicles, the demand for EV batteries is expected to rise sharply in the coming years. This is an encouraging sign, though Straubel explained that the demand shift to electric vehicles could be very challenging for automakers, particularly those that are late to the EV game. The Redwood CEO even stated that the challenges connected to battery supply in the coming years could be a “2.0” version of the ongoing semiconductor shortage.
“I think it’s going to be quite challenging for a lot of the automakers that are coming into this late. The market is making a dramatic shift. The demand shift toward EVs is phenomenal to see, it’s inspiring to see. But securing enough supply of both batteries and all the components that go into them is going to be challenging. I think we may see a version of the semiconductor shortage, kind of like a 2.0 version of that, coming in a few years as so many new automakers ramp up their EV production,” Straubel said.
Battery recycling is still in its early stages, and while companies like Panasonic are poised to use Redwood’s recycled battery components for its cell production in Tesla’s Gigafactory Nevada later this year, the percentage of batteries produced today that use recycled materials is still very small. Speaking about where he believes battery recycling would be in the near future, Straubel noted that he believes Redwood’s work would help prove that recycled batteries are a feasible solution.
“Batteries are amazing because they are so recyclable. More than 90% of the critical materials in the battery could be reused many, many times without degradation. Today, the batteries that we buy and put into our products admittedly still have a pretty small recycled material content, but this is changing fast… We’re demonstrating and showing that you can make batteries that have very high percentage (of recycled materials) and still have extremely good performance and exceptional life,” the Redwood CEO said.
Being a Tesla co-founder, it was no surprise that the Redwood CEO was asked about his long tenure at the electric vehicle maker. The CNN anchor even mentioned one of Elon Musk’s past statements, where the CEO noted that Tesla would not exist without Straubel. The former Tesla CTO responded by stating that he actually enjoyed his tenure at Tesla, and he roots for the company every day. He also noted that he believes everyone should root for his previous employer for the sake of the planet and its future.
“Tesla was an amazing adventure. I had such a fun time there helping build everything with the team. It is a wonderful team, and part of the joy of being there for so long was the caliber of the engineers and the people that made up that group. I still root for the Tesla team every single day. I love the mission and I love the company. I think we all need to root for them for the sake of the planet and the future,” Straubel noted.

Tesla confirms that work on Dojo 3 has officially resumed
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo 3,” Elon Musk wrote in a post on X.
Tesla has restarted work on its Dojo 3 initiative, its in-house AI training supercomputer, now that its AI5 chip design has reached a stable stage.
Tesla CEO Elon Musk confirmed the update in a recent post on X.
Tesla’s Dojo 3 initiative restarted
In a post on X, Musk said that with the AI5 chip design now “in good shape,” Tesla will resume work on Dojo 3. He added that Tesla is hiring engineers interested in working on what he expects will become the highest-volume AI chips in the world.
“Now that the AI5 chip design is in good shape, Tesla will restart work on Dojo3. If you’re interested in working on what will be the highest volume chips in the world, send a note to AI_Chips@Tesla.com with 3 bullet points on the toughest technical problems you’ve solved,” Musk wrote in his post on X.
Musk’s comment followed a series of recent posts outlining Tesla’s broader AI chip roadmap. In another update, he stated that Tesla’s AI4 chip alone would achieve self-driving safety levels well above human drivers, AI5 would make vehicles “almost perfect” while significantly enhancing Optimus, and AI6 would be focused on Optimus and data center applications.
Musk then highlighted that AI7/Dojo 3 will be designed to support space-based AI compute.
Tesla’s AI roadmap
Musk’s latest comments helped resolve some confusion that emerged last year about Project Dojo’s future. At the time, Musk stated on X that Tesla was stepping back from Dojo because it did not make sense to split resources across multiple AI chip architectures.
He suggested that clustering large numbers of Tesla AI5 and AI6 chips for training could effectively serve the same purpose as a dedicated Dojo successor. “In a supercomputer cluster, it would make sense to put many AI5/AI6 chips on a board, whether for inference or training, simply to reduce network cabling complexity & cost by a few orders of magnitude,” Musk wrote at the time.
Musk later reinforced that idea by responding positively to an X post stating that Tesla’s AI6 chip would effectively be the new Dojo. Considering his recent updates on X, however, it appears that Tesla will be using AI7, not AI6, as its dedicated Dojo successor. The CEO did state that Tesla’s AI7, AI8, and AI9 chips will be developed in short, nine-month cycles, so Dojo’s deployment might actually be sooner than expected.

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.
