Solid State Battery Technology, a Tesla Gigafactory Killer?

Published

on

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 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 CarNewsChinaIt 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:

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

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.

Throw in one of the many incentives it is offering currently, and there will surely be some takers.

Tesla rival’s CEO makes shock suggestion to customers about Model Y

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

Tesla rival Xiaomi is experiencing demand that is off-the-charts with its new YU7 crossover, which competes with the Model Y. The company’s CEO has stated that demand is truly outpacing what it can build, and that customers in limbo should consider the Model Y because “it’s a great car.”

The Xiaomi YU7 has already gained an incredible number of orders so far. Its launch a few months ago had consumers busting down doors to place an order before others, and demand has been so high that customers will wait, on average, between 56 and 59 weeks for delivery.

Tesla Model Y meets new competition from Xiaomi 

Within 18 hours, Xiaomi received about 240,000 orders, CarScoops reported. Some customers are truly interested in the vehicle, but cannot wait the extended period to take delivery as they might need a car now.

Xiaomi CEO Lei Jun said on social meida that there are other cars out there that would be suitable as a replacement to the YU7:

“If you need to buy a car quickly, other China-produced new energy vehicles are pretty good.”

He explicitly mentioned the Model Y, Xpeng G7, and Li Auto i8.

Regarding the Model Y, he said:

“The Model Y is a great car, and Tesla also announced a number of promotions yesterday, so you might want to consider it.”

The Model Y has been the best-selling car in the world over the past two years, and it still leads in many markets as the most sought-after EV. However, in China, there are so many formidable competitors that customers are seemingly going for whatever they can get to first.

Of course, a car is a car, but Tesla has gained a more notable reputation for its industry-leading tech and driver assistance systems, including City Autopilot, which has been used in China for a few months now.
