Tesla has filed a patent that aims to recover undamaged and unutilized nickel and cobalt, two crucial raw materials in battery cells. The patent outlines the use of an electrochemical dissolution to recover the Earth metals for recycling purposes, moving toward a more efficient supply chain as some battery materials are becoming hard to obtain due to global supply chain shortages.
The patent is titled “Metal Sulfate Manufacturing System via Electrochemical Dissolution” and was filed by three Tesla engineers. The automaker filed it on July 29th, 2021, just days after the Q2 2021 Earnings Call, where Tesla reported its eighth consecutive profitable quarter.
The patent
Battery manufacturing has been a central focus of electric car companies since day 1. Batteries are the lifeblood of electric cars, and as more companies enter the EV sector, batteries and battery materials are becoming less available due to growing demand. One way to utilize EV batteries after their lifespan has come to an end is to recover the undamaged and unutilized raw materials from the non-functioning cells. Battery cell recycling could be the best and most efficient way to alleviate battery material supply shortages and increase the number of available cells for a company’s products. Nickel and cobalt are two materials that would be ideal for this patent: nickel due to its low availability and cobalt due to its environmental effects and commonly immoral mining practices.
“Nickel and cobalt sulfates are often used as raw materials for lithium-ion battery cathode material precursors, nickel metal hydride battery cathodes, and nickel cadmium battery cathodes. It is sometimes difficult or expensive to purchase metal sulfate products from the market due to their limited availability,” the patent states. “As a result, several companies synthesize metal sulfate solutions via dissolution in sulfuric acid from more readily available metal products, such a nickel powder, nickel briquette, cobalt powder, and cobalt briquette. However, the growth of the electric and hybrid-electric vehicle markets is expected to continue into the future and result in a shortage of metal powders and briquettes, in addition to sulfates.”
Tesla aims to utilize an electrolyte bath container to hold a solution for battery cells to be placed in. The bath would utilize “relatively dilute sulfuric acid” in an electrochemical dissolution device with an anode and a cathode, synthesizing a metal sulfate solution from the cathodes, powders, or briquette materials. The metals can be extracted from the cells through the bath, which will have low-voltage currents applied to it, freeing the undamaged materials from the battery.

Why this is a big deal
The patent, if granted, would open doors for Tesla to recover some of the most crucial elements of an electric vehicle or energy storage battery. With the increased demand for these materials, Tesla could cut its expenditures for material mining and new battery cell production, allowing the company to remove itself from the extensive waiting list for these materials. Costs for both nickel and cobalt have skyrocketed recently. Cobalt has increased in price significantly since September 2019, increasing by 62.64% since then. Nickel is up 9.25% in the same time frame, according to Investing.com.
Musk’s callout for Nickel and Cobalt
Tesla CEO Elon Musk has been requesting nickel for several quarters, even requesting a supplier to offer its services to the automaker for a “giant contract.” Tesla has signed supply deals with Australia’s BHP and has also been in talks with Canadian and Indonesian companies.
Musk said during the Q2 2020 Earnings Call:
“Well, I’d just like to reemphasize, any mining companies out there, please mine more nickel, OK? Wherever you are in the world, please mine more nickel, and don’t wait for nickel to go back to some long — some high point that you experienced some five years ago or whatever. Go for efficiency, as environmentally friendly, nickel mining at high volume. Tesla will give you a giant contract for a long period of time if you mine nickel efficiently and in an environmentally sensitive way. So hopefully, this message goes out to all mining companies.”
Cobalt, a highly controversial metal that is crucial for cell stability, is an element Tesla is attempting to move away from. However, if the automaker can get its hands on reusable cobalt from old batteries, it would likely not say no to the option of having it on hand. Mining practices have widely been characterized as immoral and have taken advantage of child labor. Tesla has worked its way around these issues through routine due diligence checks at its supplier’s mines, but still, getting cobalt out of the supply chain altogether is the goal. Tesla is working toward a zero-cobalt LPF cell in China, and suppliers like Panasonic have also indicated that they could have cobalt-free cells ready in 2-3 years.

Summary:
“Modular data center hardware systems for artificial intelligence computing, comprised of computer servers, computer hardware for artificial intelligence processing, computer networking hardware, electrical power distribution units, and… pic.twitter.com/3l85DsKadl— Robin (@xdNiBoR) June 19, 2026
According to the official goods and services description in the application, Tesla describes ‘MEGAPOD’ as:
“Modular data center hardware systems for artificial intelligence computing, comprised of computer servers, computer hardware for artificial intelligence processing, computer networking hardware, electrical power distribution units, and cooling systems, sold as a unit; self-contained modular computing hardware systems for artificial intelligence workloads; integrated computer hardware platforms for artificial intelligence computing, namely, enclosures containing computer hardware, power distribution hardware, and cooling hardware, sold as a unit; downloadable software for monitoring, managing, optimizing, and regulating modular artificial intelligence computing hardware systems.”
This description specifies complete, self-contained modular units that integrate servers and specialized AI processing hardware with networking components, power distribution, and cooling systems. It also includes associated downloadable software for oversight and optimization of these systems. The language emphasizes hardware sold “as a unit” and enclosures that combine the necessary elements for AI computing workloads.
Tesla has an established history of developing and commercializing modular hardware systems. Its Megapack product line, for example, consists of utility-scale battery energy storage systems designed as containerized units for grid applications. The MEGAPOD filing follows a similar pattern of protecting a name for modular, integrated hardware platforms, this time focused on artificial intelligence computing infrastructure.
This could be an early move, especially as Tesla did not have trademark rights to the word ‘Cybercab,’ the name of its self-driving, ride-hailing-focused vehicle.
Trademark applications of this type allow companies to secure priority rights to a name for defined categories of goods and services. The USPTO examines applications for compliance with legal requirements, including distinctiveness and absence of conflicts with prior marks. If the application proceeds successfully through examination, publication, and any opposition period, it could result in a federal trademark registration providing nationwide protection. This is what Tesla’s obvious intention is with ‘MEGAPOD.’
Public reports and analysis suggest MEGAPOD could represent modular, container-style AI computing pods designed for easy deployment. These would bundle servers, AI accelerators, power systems, and cooling into self-contained units suitable for distributed AI workloads. This approach aligns with Tesla’s announced AI compute strategy.
In March 2026, Elon Musk outlined plans for “Digital Optimus” (also referred to as Macrohard), a joint Tesla-xAI project for AI agents capable of handling complex digital tasks. The plans include running these agents on Tesla’s AI4 hardware in parked vehicles as well as dedicated compute units installed at Supercharger stations, which collectively offer substantial unused electrical capacity.
What is Digital Optimus? The new Tesla and xAI project explained
A modular hardware platform like the one described in the ‘MEGAPOD’ filing would support scalable, rapid deployment of such distributed compute resources. It could complement Tesla’s other AI infrastructure efforts, including the Dojo supercomputer used for training models and the development of AI systems for autonomous driving and robotics, by enabling edge or regional AI inference without reliance on traditional centralized data centers.
In a notable intersection of Big Tech powerhouses, Meta, led by Mark Zuckerberg, has partnered with Canadian energy infrastructure giant Enbridge on a significant renewable energy initiative that will rely on battery technology from Elon Musk’s Tesla.
The project, which was announced this week, marks another step in Meta’s aggressive push to power its expanding data center operations with clean energy, dispelling many of the complaints people have about them.
This new development is located near Cheyenne, Wyoming, and will feature a 365-megawatt (MW) solar farm paired with a 200 MW/1,600 megawatt-hour (MWh) battery energy storage system, also known as BESS. Tesla is providing the batteries for the project, valued at roughly $200 million.
The story was originally reported by Utility Dive.
This Wyoming project represents the first phase of Enbridge and Meta’s joint “Cowboy Project.” Once operational, it will deliver power to Meta’s regional data centers through Cheyenne Light, Fuel, and Power under Wyoming’s Large Power Contract Service tariff.
This tariff, originally developed in collaboration with Microsoft and Black Hills Energy, is designed specifically for large loads like data centers. It ensures that the renewable supply serves hyperscale customers without impacting retail electricity rates for other users.
The battery system will operate under a long-term tolling agreement, providing dispatchable capacity that enhances grid reliability. During periods of high demand, the utility can access the backup generation, addressing one of the key challenges of integrating large-scale renewables with the explosive growth of data center electricity demand driven by artificial intelligence.
This latest collaboration builds on prior joint efforts between Enbridge and Meta in Texas, including the 600 MW Clear Fork Solar, 152 MW Easter Wind, and 300 MW Cone Wind projects. Together with the Wyoming initiative, the companies have now partnered on roughly 1.6 gigawatts (GW) of combined solar, wind, and storage capacity.
The deal highlights the intensifying demand for reliable, low-carbon power from technology giants. Meta has committed to supporting its data center growth with renewable energy, joining peers like Microsoft and Google in seeking large-scale solutions. Enbridge’s Allen Capps described the project as “one of the larger utility-scale battery installations supporting U.S. data center operations and growth.”
The involvement of Tesla’s battery technology adds an intriguing layer, linking two of the world’s most prominent tech leaders—Zuckerberg and Musk—in the clean energy transition.
As data centers continue to drive unprecedented electricity load growth across the United States, projects like this one illustrate how hyperscalers are turning to strategic partnerships with traditional energy players and innovative storage solutions to meet both sustainability goals and reliability needs.

Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO
SpaceX has secured an option to acquire Cursor AI for $60 billion ahead of its historic IPO.
SpaceX announced today it has struck a deal with AI coding startup Cursor, securing the option to acquire the company outright for $60 billion later this year, while committing $10 billion for joint development work in the interim. The announcement described the partnership as building “the world’s best coding and knowledge work AI,” and comes just days after Cursor was separately reported to be raising $2 billion at a valuation above $50 billion.
The move makes strategic sense given where each company currently stands. Cursor currently pays retail prices to Anthropic and OpenAI to the same companies competing directly against it with Claude Code and Codex. That means every dollar of revenue Cursor earns partially funds its own competition. With SpaceX bringing computational infrastructure to the Cursor platform, that could reduce Cursor’s dependence on OpenAI and Anthropic’s Claude AI as its providers. Access to SpaceX’s Colossus supercomputer, with compute equivalent to one million Nvidia H100 chips, gives Cursor the infrastructure to run and train its own models at a scale it could never afford independently. That one change restructures the entire unit economics of the business.
Elon Musk teases crazy outlook for xAI against its competitors
Cursor’s $2 billion in annualized revenue and enterprise reach across more than half of Fortune 500 companies gives SpaceX something its xAI subsidiary currently lacks, which is a proven, fast-growing software business with real enterprise distribution.
For Cursor, SpaceX’s $10 billion in joint development funding is transformational. Cursor raised $3.3 billion across all of 2025 to reach that $2 billion in revenue. A single $10 billion commitment from SpaceX, even as a development payment rather than an acquisition, dwarfs everything Cursor has raised in its entire existence. That capital accelerates product development, enterprise sales infrastructure, and proprietary model training simultaneously.
The timing is deliberate. SpaceX filed confidentially with the SEC on April 1, 2026, targeting a June listing at a $1.75 trillion valuation, in what would be the largest public offering in history. The company is expected to begin its roadshow the week of June 8, with Bank of America, Goldman Sachs, JPMorgan, and Morgan Stanley serving as underwriters. Adding Cursor to the portfolio before that roadshow gives IPO investors a concrete enterprise software revenue story to price in, alongside rockets and satellite internet.
The deal also addresses a weakness that became visible after February’s xAI merger. Several xAI co-founders departed following that acquisition, and SpaceX had already hired two Cursor engineers, signaling where its AI talent strategy was heading. Cursor, for its part, faces a pricing disadvantage competing against Anthropic’s Claude Code.
Whether SpaceX exercises the full acquisition option before its IPO or after remains the open question. Either way, this deal reshapes what investors will be buying into when SpaceX goes public.
