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.
Investor's Corner
Tesla price target boost from its biggest bear is 95% below its current level
Tesla stock (NASDAQ: TSLA) just got a price target boost from its biggest bear, Gordon Johnson of GLJ Research, who raised his expected trading level to one that is 95 percent lower than its current trading level.
Johnson pushed his Tesla price target from $19.05 to $25.28 on Wednesday, while maintaining the ‘Sell’ rating that has been present on the stock for a long time. GLJ has largely been recognized as the biggest skeptic of Elon Musk’s company, being particularly critical of the automotive side of things.
Tesla has routinely been called out by Johnson for negative delivery growth, what he calls “weakening demand,” and price cuts that have occurred in past years, all pointing to them as desperate measures to sell its cars.
Johnson has also said that Tesla is extremely overvalued and is too reliant on regulatory credits for profitability. Other analysts on the bullish side recognize Tesla as a company that is bigger than just its automotive side.
Many believe it is a leader in autonomous driving, like Dan Ives of Wedbush, who believes Tesla will have a widely successful 2026, especially if it can come through on its targets and schedules for Robotaxi and Cybercab.
Justifying the price target this week, Johnson said that the revised valuation is based on “reality rather than narrative.” Tesla has been noted by other analysts and financial experts as a stock that trades on narrative, something Johnson obviously disagrees with.
Dan Nathan, a notorious skeptic of the stock, turned bullish late last year, recognizing the company’s shares trade on “technicals and sentiment.” He said, “From a trading perspective, it looks very interesting.”
Tesla bear turns bullish for two reasons as stock continues boost
Johnson has remained very consistent with this sentiment regarding Tesla and his beliefs regarding its true valuation, and has never shied away from putting his true thoughts out there.
Tesla shares closed at $431.40 today, about 95 percent above where Johnson’s new price target lies.

I subscribed to Tesla Full Self-Driving after four free months: here’s why
It has been incredibly valuable to me, and that is what my main factor was in considering whether to subscribe or not. It has made driving much less stressful and much more enjoyable.
I have been lucky enough to experience Tesla Full Self-Driving for the entire duration of my ownership experience for free — for four months, I have not had to pay for what I feel is the best semi-autonomous driving suite on the market.
Today, my free trial finally ran out, and I had two choices: I could go without it for a period until I felt like I absolutely needed it, or I could subscribe to it, pay $99 per month, and continue to experience the future of passenger transportation.
I chose the latter, here’s why.
Tesla Full Self-Driving Takes the Stress Out of Driving
There are a handful of driving situations that I don’t really enjoy, and I think we all have certain situations that we would just rather not encounter. This is not to say that I won’t ever experience them as someone who has driven a car for 15 years (it feels weird saying that).
I don’t love to drive in cities; I really don’t like driving on I-695 on my way to Baltimore, and I truly hate parallel parking. All three things I can do and have done, all three within the past few weeks, too.

However, if I can avoid them, I will, and Tesla Full Self-Driving does that for me.
Tesla Full Self-Driving Eliminates the Monotony
I drive to my alma mater, Penn State University, frequently in the Winter as I am a season ticket holder to Wrestling and have been for 16 years now.
The drive to State College is over two hours and over 100 miles in total, and the vast majority of it is boring as I travel on Rt 322, which is straight, and there is a lot of nature to look at on the way.
I am willing to let the car drive me on that ride, especially considering it is usually very low traffic, and the vast majority of it is spent on the highway.
The drive, along with several others, is simply a boring ride, where I’d much rather be looking out the windshield and windows at the mountains. I still pay attention, but having the car perform the turns and speed control makes the drive more enjoyable.
Tesla Full Self-Driving Makes Navigating Easier
Other than the local routes that I routinely travel and know like the back of my hand, I’ve really enjoyed Full Self-Driving’s ability to get me to places — specifically new ones — without me having to constantly check back at the Navigation.
Admittedly, I’ve had some qualms with the Nav, especially with some routing and the lack of ability to choose a specific route after starting a drive. For example, it takes a very interesting route to my local Supercharger, one that nobody local to my area would consider.
But there are many times I will go to a new palce and I’m not exactly sure where to go or how to get there. The Navigation, of course, helps with that. However, it is really a luxury to have my car do it for me.
To Conclude
There was no doubt in my mind that when my Full Self-Driving trial was up, I’d be subscribing. It was really a no-brainer. I am more than aware that Full Self-Driving is far from perfect, but it is, without any doubt, the best thing about my Tesla, to me.
It has been incredibly valuable to me, and that is what my main factor was in considering whether to subscribe or not. It has made driving much less stressful and much more enjoyable.

Tesla Diner becomes latest target of gloom and doom narrative
The Tesla Diner has been subject to many points of criticism since its launch in mid-2025, and skeptics and disbelievers claim the company’s latest novel concept is on its way down, but there’s a lot of evidence to state that is not the case.
The piece cites anecdotal evidence like empty parking lots, more staff than customers during a December visit, removed novelty items, like Optimus robot popcorn service and certain menu items, the departure of celebrity chef Eric Greenspan in November 2025, slow service, high prices, and a shift in recent Google/Yelp reviews toward disappointment.
The piece frames this as part of broader Tesla struggles, including sales figures and Elon Musk’s polarizing image, calling it a failed branding exercise rather than a sustainable restaurant.
This narrative is overstated and sensationalized, and is a good representation of coverage on Tesla by today’s media.
Novelty Fade is Normal, Not Failure
Any hyped launch, especially a unique Tesla-branded destination blending dining, Supercharging, and a drive-in theater, naturally sees initial crowds taper off after the “Instagram effect” wears down.
Tesla makes major change at Supercharger Diner amid epic demand
This is common for experiential spots in Los Angeles, especially pop-up attractions or celebrity-backed venues. The article admits early success with massive lines and social media buzz, but treats the return to normal operations as “dying down.”
In reality, this stabilization is a healthy sign of transitioning from hype-driven traffic to steady patronage.
Actual Performance Metrics Contradict “Ghost Town” Claims
- In Q4 2025, the Diner generated over $1 million in revenue, exceeding the average McDonald’s location
- It sold over 30,000 burgers and 83,000 fries in that quarter alone. These figures indicate a strong ongoing business, especially for a single-location prototype focused on enhancing Supercharger experiences rather than competing as a mass-market chain
It’s not a ghost town lol. The @Tesla Diner still had over 30,000 burger orders and 83,000 fries orders in Q4. The diner generated over $1M in revenue in Q4, a $4M annual run rate, which is more than the average McDonald’s…. pic.twitter.com/XvAGLUqxej

Conflicting On-the-Ground Reports
While the article, and other similar pieces, describe a half-full parking lot and sparse customers during specific off-peak visits, other recent accounts push back:
- A January 2026 X post noted 50 of 80 Supercharger stalls were busy at 11 a.m., calling it “the busiest diner in Hollywood by close to an order of magnitude
TESLA DINER 🍔
Frantic!!!
Crazy busy. pic.twitter.com/wMbmr8SFFn
— Rich & Sharon (@HullTeslaModel3) January 4, 2026
- Reddit discussions around the same time describe it as not empty when locals drive by regularly, with some calling the empty narrative “disingenuous anti-Tesla slop.”
When we visited it last week it was packed. We had to wait to enter, get a table and go to the restroom. We were lucky to find a spot to charge.

Bottom Line
The Tesla Diner, admittedly, is not the nonstop circus it was at launch–that was never sustainable or intended. But, it’s far from “dying” or an “empty pit stop.”
It functions as a successful prototype: boosting Supercharger usage, generating solid revenue, and serving as a branded amenity in the high-traffic EV market of Los Angeles.
