Solid State Battery Technology, a Tesla Gigafactory Killer?
With 2014 coming to an end, automotive battery news has been trickling out and solid state battery technology appears, again.
In early December, Volkswagen acquired a small equity stake in Stanford-based QuantumScape and Daimler recently announced that its lithium production output will be larger in 2015 due to a new battery plant in Kamenz, Germany, said to be ready by mid-2015.
The VW news keeps the the solid state battery thread for 2014 going as scientists point to its reported improved energy density over lithium-ion technology. A solid state battery does not use a liquid electrolyte like a lithium battery does and, in theory, a solid electrolyte can hold more energy. Yes, please.
Getting rid of an electrolyte—no liquid—can also improve battery safety and reduce costs due to less cooling electronics and micro-controllers needed for pack management, thus reducing weight too, according to Harvard Business Review.
What about downsides to this technology? A solid-state battery has electrical contacts or, electrodes, that are applied to a solid electrolyte—similar to a thin-film solar panel process—and if there’s a lack of uniformity in this process, it can cause short circuits. However, this type of manufacturing application has been done in the thin-film solar area and these obstacles should be easy to overcome.

Earlier this year, Scientific American did a profile on Ann Arbor, Michigan-based Sakti3 and their push with solid-state battery technology and move closer to the “god” battery.
Ann Marie Sastry, co-founder and CEO of the company, said, “that the company’s prototype solid-state lithium battery cells have reached a record energy density of 1,143 Watt-hours per liter—more than double the energy density of today’s best lithium-ion batteries.”
However, as Elon Musk said in the most recent Tesla earnings call,
“Talk is super cheap, the battery industry has to have more BS in it than any industry I’ve ever encountered. It’s insane.”
So is this technology an immediate challenger to Tesla Motors’ Gigafactory strategy? Will this battery technology get ahead of Tesla, due its battery equipment investment at the Gigafactory being close to complete and, thus, no turning back?
No and the reason is battery development takes a lot of time and these recent statements by Sakti3 in the Scientific American article bear this out.
Sakti3 says it’s close to the end of lab work—custom prototype manufacturing line—but then the next step is on to small scale production and this could take a another year or two of testing before you hit mass production.
That rules out GM going with this type of battery for their mass-produced battery electric vehicle for 2016 or 2017. Plus, Sakti3 mentioned its first aim is small-scale electronics and smartphones.
More importantly, JB Straubel and Tesla Motors aren’t looking for the God battery for 2017. Everyone seems to be looking for this right chemistry to scale with at this point. Granted, these are big automakers that could scale quickly as long their company culture is rowing in the same direction.
Tesla has their battery composition set and plan to cut 30 percent or more of costs out of their current battery price, which stands anywhere from $260 to maybe $220 kWh. Take the high end and with the cost savings, the battery pack is at $185 kWh, approximately.
That’s just over $10,000 for a battery pack for a 55kWh battery pack—assumption 30% battery cost reduction translates to battery pack. Also, my assumption above is that a Gen 3 car will be smaller and could get 220 miles with a smaller battery pack.
The rub for me is that the roadmap is in place for Tesla Motors battery chemistry and this should get them to a mass-market electric vehicle, first. Maybe other automakers are close to a new chemistry, but automotive testing and applications take time.
In the end, I’m all for the god battery sooner rather than later but Tesla Motors just isn’t waiting for it.
Tesla Cybercab rides are officially open to the public in Austin, Texas, as the company confirmed on Thursday following its launch event that the two-seater would be available in the company’s Robotaxi fleet.
Cybercab is Tesla’s first vehicle completely void of any manual controls. It has no steering wheel and no pedals, and it will utilize Tesla’s Full Self-Driving fleet to operate. The first rides have already happened, as those at the event were able to hail a Cybercab to any location within the company’s geofence in Austin.

The addition of Cybercab to the public Robotaxi fleet is a major statement in Tesla’s trek to launch fully autonomous driving. For years, critics have complained about the need for drivers to continuously supervise the vehicle.
With Cybercab, there are no manual controls in the cockpit other than to control the seat, the center screen, and the climate. The vehicle is fully geared toward being a living room on wheels in a sense: equipped with Starlink V5 satellites, CEO Elon Musk said the vehicle would enable 4K live video, gaming, and other entertainment options during travel.

Musk noted that Cybercab is “designed and built for maximally efficient autonomous operation.”
Tesla continues to push the envelope on autonomy, and over the next several months, the company could start selling Cybercab units to the public.
The company opened up a public interest form on its website to gauge demand, and many have already submitted requests to purchase a fleet of Cybercab units for their own personal ride-hailing side hustle.
The launch of Cybercab in this area marks a major accomplishment for Tesla, as it also announced that it has reached 1 million unsupervised autonomous miles since launching driverless rides on the Robotaxi fleet.
Things are moving along at a fine pace, and although we have waited for this for some time, the day has finally come when Tesla is offering self-driving rides of some kind to the public.
Tesla has quietly opened a public interest form for companies that want to buy fleets of its purpose-built Cybercab robotaxis, marking the first official channel for commercial purchases of the two-seat autonomous vehicle. The form went live on September 3, the same day Tesla hosted an invite-only Cybercab launch event in Austin, Texas.
Tesla titled the page “Help Us Build Our Robotaxi Network.” Applicants provide name, email, phone number, company name, and deployment region. They then select one or more categories: Cybercab fleet vehicle purchasing, mobility hubs and infrastructure, event collaboration, or other. Tesla says a representative will follow up with those who express commercial interest.

Until now, the company had no public ordering path for the vehicle, which was first shown as a concept at the October 2024 “We, Robot” event.
The Cybercab is designed from the ground up for unsupervised operation. It has no steering wheel and no pedals.
Regulatory filings list a 48-kilowatt-hour battery, a single 219-horsepower front motor, a curb weight of 3,113 pounds, and an EPA-adjusted range near 290 to 300 miles. Tesla has already registered dozens of the vehicles with Texas authorities and has been testing them on public streets around Austin.
Tesla Cybercab sightings broaden well outside of Austin with autonomy in focus
The company’s existing Robotaxi service, which currently uses modified Model Y vehicles in parts of Texas and Florida, is expected to add Cybercabs as production ramps up at Gigafactory Texas.
The form signals that Tesla is preparing to treat the Cybercab as more than an in-house fleet asset. Investors and operators have discussed buying groups of the vehicles and placing them on Tesla’s ride-hailing network, with Tesla taking a platform fee. High-profile figures have publicly stated plans to acquire fleets if Tesla allows third-party ownership.
The new page gives those parties a direct way to register interest rather than waiting for a conventional configurator.
Whether the form leads quickly to firm purchase agreements remains unclear. Regulatory approval for widespread unsupervised operation still varies by state, and Tesla has not published pricing or delivery timelines for fleet customers. The company has previously discussed a target price near $25,000 to $30,000 per vehicle.
For now, the form is an early signal that Tesla wants partners to help scale the network rather than operate every Cybercab itself.
Pairing the launch of the Cybercab fleet form with the Austin event is no coincidence. Tesla is inviting businesses to participate in the next phase of its Robotaxi plan at the moment the production vehicle first appears in public.
Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
