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 Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
