Solid State Battery Technology, a Tesla Gigafactory Killer?

Published

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 has pushed a crazy new incentive package, known as the “Luxe Package,” on the flagship Model S and Model X, along with a $10,000 price increase on each trim level.

The move aims to likely bolster margins for the company on the two cars while also giving those who choose to buy the Tesla lineup mainstays a variety of awesome advantages, including Free Supercharging, Full Self-Driving, and other add-ons.

Tesla is offering a crazy Supercharging incentive on its two ‘sentimental’ vehicles

Last night, Tesla launched the “Luxe Package” for the Model S and Model X, which includes the following four add-ons:

Full Self-Driving (Supervised) – Your car will be able to drive itself almost anywhere with minimal driver intervention
Four-Year Premium Service – Wheel and Tire Protection, Windshield Protection, and Recommended Maintenance
Supercharging – Charge for free at 70,000+ Superchargers worldwide
Premium Connectivity – Listen to music, stream movies, monitor live traffic, and more – no Wi-Fi needed

Full Self-Driving is priced at $8,000. Free Supercharging for the life of the car is between $10,000 and $15,000 over the life of the vehicle, although Tesla has valued it at $5,000 in recent promotions.

Free Premium Connectivity is roughly $1,000, and the four-year tire, wheel, windshield, and maintenance plan is about $3,200.

🚨 Tesla increased the price of both the Model S and Model X by $10,000, but both vehicles now include the “Luxe Package,” which includes:
-Full Self-Driving
-Four years of included maintenance, tire and wheel repairs, and windshield repairs/replacements
-Free lifetime… pic.twitter.com/LKv7rXruml

In all, the value is over $25,000, but this is loosely based on usage.

The Model S and Model X are low contributors to Tesla’s overall sales figures, as they make up less than five percent of sales from a quarterly perspective and have for some time.

As they are certainly the luxury choices in Tesla’s lineup, the Model 3 and Model Y are the bigger focus for the company, as a significantly larger portion of the company’s sales is made up of those vehicles.

The Luxe Package is an especially good idea for those who drive high-mileage and plan to use the Model S or Model X for commuting or long drives. The free Supercharging makes the deal worth it on its own.

As for the price bumps, each of the vehicles are now priced as follows:

Model S All-Wheel-Drive: $94,990
Model S Plaid: $109,990
Model X All-Wheel-Drive: $99,990
Model X Plaid: $114,990

Tesla Roadster could have a formidable competitor with BYD’s 3000-HP supercar

The Roadster is one of the most anticipated vehicles of all time, especially because we’ve all had to wait so long for it. On its own, it will have a 1.9-second 0-60 MPH acceleration rate, which is projected to be better than the 2.3 seconds the U9 Track Edition will offer.

The Tesla Roadster is on the way, and yes, we know we’ve heard that for quite a few years. But when it comes, it might have a formidable competitor, and it might come from no one other than Chinese rival BYD.

BYD’s Yangwang U9 Track Edition is a new configuration of the U9 supercar that hit the Chinese Ministry of Information Technology (MIIT) database recently.

The vehicle was first spotted on the MIIT database by CarNewsChina. It will have a quad-motor powertrain, each dedicated to one wheel. Instead of the 1,287 horsepower that comes with the standard U9 configuration, the Track Edition will have 2,977.

There are only two cars that even come close in terms of horsepower: the Lotus Evija with 1,972 and the Rimac Nevera at 1,914 horsepower. The Tesla Roadster is expected to have somewhere around 1,000 horsepower.

The Roadster is one of the most anticipated vehicles of all time, especially because we’ve all had to wait so long for it. On its own, it will have a 1.9-second 0-60 MPH acceleration rate (without the SpaceX package, which brings the projection to 1.1 seconds), which is projected to be better than the 2.3 seconds the U9 Track Edition will offer.

The Roadster also beats the U9 Track Edition in projected top speed and range. The Roadster could top out at over 250 MPH, compared to the 217 conservative projection for the U9 Track Edition.

Range on the Roadster is 620 miles, beating 280 miles for the BYD.

The U9 Track Edition will also have some additional features compared to its base model. These include some aerodynamic additions, like a carbon fiber rear wing, diffuser, and an adjustable front splitter and adjustable rear wing.

The latter two are optional, but if you have enough scratch to drop on this car, you’re probably adding those two features as well.

We hope that both the Roadster and U9 Track Edition will hit a drag strip, road course, or even a superspeedway for some racing. It would truly be something for EV fans to drool over.

Tesla is breaking even its own rules to cap off an intense Q3

Tesla is pulling out all the stops to have a strong Q3 as the EV tax credit will phase out.

Tesla is breaking its own rules by advertising on various platforms in an effort to sell as many cars as possible before the end of the $7,500 electric vehicle tax credit.

Tesla has had a very polarizing perspective on advertising. Over the years, it has taken on different attitudes toward spending any money on marketing. It has instead put those dollars into research and development to make its vehicles more advanced.

Back in 2019, Tesla CEO Elon Musk talked about the company advertising its vehicles and energy products:

Tesla does not advertise or pay for endorsements. Instead, we use that money to make the product great. https://t.co/SsrfOq1Xyc
— Elon Musk (@elonmusk) May 19, 2019

In 2021, in response to analyst Gary Black, who has pushed for Tesla to have a PR or marketing department, Musk said:

Other companies spend money on advertising & manipulating public opinion, Tesla focuses on the product.
I trust the people.
— Elon Musk (@elonmusk) April 27, 2021

However, this did not hold as Tesla’s strategy for the long haul. While Musk did resist advertising for a long time, Tesla started placing ads on platforms like X, Google, and YouTube several years back. It’s pretty rare that Tesla pushes these ads, however.

The company’s stance on setting aside capital for advertising seems to be circumstantial. Right now, it is working to sell as many vehicles as it can before the tax credit comes to a close.

As a result, it is pushing some ads on YouTube:

It’s a move that makes sense considering the timing. With just six weeks roughly left in the quarter, Tesla is going to work tirelessly to push as many cars into customer hands as possible. It will use every ounce of effort to get its products on people’s screens.
