ZapBatt and Toshiba are partnering to unlock proven lithium titanium oxide (LTO) battery technology for micro-mobility. In a press release emailed to me, ZapBatt shared that it’s merging its proprietary artificial intelligence technology and next-gen battery hardware with Toshiba’s lithium titanium oxide battery cells.
The goal is to create a new battery option for the micro-mobility marketplace. This will enable LTO batteries to be faster, smarter, and more economical while allowing for real-time battery management and optimization.

There are three challenges of using LTO chemistry in batteries that ZapBatt is helping Toshiba solve.
- Chips. At the time, chips didn’t exist to work with LTO, however, ZapBatt’s custom LTO battery management system (BMS) is changing this. The BMS works at the unique voltages of LTO with the ability to be re-configured to adapt as the cell chemistry grows. This enables a programmable chip that works with other chemistries and voltages.
- Voltage. ZapBatt has a bi-directional adaptive terminal voltage (BATV) technology. This allows the battery system’s voltage control to be digitally controlled with software. Think of a universal adapter that allows LTO batteries to be a one-for-one swap with any lithium-ion chemistry without the need for modification to the system. The benefit is the ability to re-configure batteries for other applications at software speed.
- Energy Density. ZapBatt will use integrated AI which allows the battery to improve the system’s performance. The AI will analyze how energy is being used. One example is enhanced regenerative braking in e-bikes.
Toshiba & ZapBatt Statements
Greg Mack, Toshiba’s Vice President and General Manager of the Power Electronics Division shared the following statement about the new partnership.
“ZapBatt unlocked the potential of Toshiba’s LTO chemistry for a variety of industries and new markets with disruptive technology, moving away from the ‘miracle battery’ trap and providing a real solution hitting the market today.”
“With ZapBatt’s hardware and software, and our LTO chemistry, there is no other solution as fast, safe, and cost-effective on the market.”
Charlie Welch, CEO and Co-Founder of ZapBatt also shared a statement.
“For global carbon reduction and electrification, we need better battery solutions now, not in ten years. To address this problem, we worked with Toshiba to allow lithium titanium oxide to come alive, bridge into new markets quickly, and provide maximum economic and environmental benefit.”
“Unlike other chemistries, lithium titanium oxide is very efficient in a variety of conditions, not just on a lab bench. It’s like the Seabiscuit of batteries.”
How Toshiba’s Lithium Titanium Oxide Cells Will Work
The company noted that the cells are designed for fast charging and high-power environments with a minimal decrease in function–even after thousands of charges and uses.
These cells are ideal for micro-mobility applications and will provide up to a 100% usable charge without shortening the cycle life. They also perform in freezing temperatures as low as -30 degrees celsius.
The LTO cells also reduce operating expenses and e-waste. And they eliminate the risk of fire with ZapBatt’s LTO system. ZapBatt noted that its LTO batteries have virtually no risk for self-thermal runaway.
In addition to this, ZapBatt pointed out that its combination of machine learning and proprietary hardware will continuously improve battery performance. The software analyzes 26 data points that illustrate how the battery performs to improve charging operations.
ZapBatt’s New Hardware Solution
ZapBatt built a new hardware solution for its LTO BATV system. The BATV system allows the system to control the battery voltage input and output all digitally with software. This allows LTO batteries to integrate with a variety of applications.
Amiad Zionpur, ZapBatt’s Chief Operating Officer shared some thoughts about this technology.
“ZapBatt’s bi-directional adaptive terminal voltage (BATV) technology allows the battery to reconfigure itself based on the customer’s needs, essentially making it a universal adapter that has the potential to change the battery landscape completely.”
“Because of this unique ability, the e-bike battery can be used in many different applications, from micro-mobility to consumer products.”
My Interview With ZapBatt CEO, Charlie Welch
In June, I interviewed Charlie for CleanTechnica in a two-part series. In the first part, which you can read here, Charlie shared how he got started with ZapBatt, the difference between ZapBatt and the overall battery industry, and charging in just 15 minutes.
In the second part of our interview, which you can read here, we spoke about overlooked technologies, the industries that ZapBatt wants to impact, and availability and sustainability.

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.

The Tesla CEO shared his recent insights in a post on social media platform X.
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.
