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.

SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.

Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.

The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.

Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:

“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”

Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.

Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.

This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.

Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:

“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”

Starlink recently crossed a massive milestone of over 10 million subscribers.

Tesla nears closure of Full Self-Driving purchasing option

The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.

Tesla is nearing the closure of its Full Self-Driving outright purchasing option, which will be removed on February 14, meaning Saturday will be the last time it can be bought as a non-subscription.

Tesla is aiming to move its Full Self-Driving suite to a subscription-only platform, a move that will enable people to only pay monthly for the semi-autonomous driving functionality.

The move to bring FSD to this type of purchasing program comes after CEO Elon Musk noted in January that Tesla would move away from the outright purchase option.

It is currently priced at $8,000 for the outright option to use Full Self-Driving, a substantial decrease compared to the $15,000 it was priced at one time. For the monthly subscription, it is just $99 per month, but that price will change, likely increasing as things get more advanced.

Tesla is overhauling its Full Self-Driving subscription for easier access

We say it will likely increase because there is no indication of how Tesla will price FSD. There has been some speculation that Tesla could utilize a tiered system to price FSD, which would potentially allow owners to pick and choose a set of features that would be most ideal for them.

This would potentially introduce an even more affordable option for FSD use, but this is unconfirmed. The reason many say this could be an option for Tesla is the fact that if the price goes up further, the take rate, which is currently around 12 percent at its most recent estimate, could be lower.

Musk needs 10 million active Full Self-Driving subscriptions to unlock one of the tranches of his newest compensation package.

The move to a subscription-only platform has its positives and negatives, and owners have been more than vocal about these since Musk confirmed the move.

Positives

  • Lower barrier to entry and higher potential adoption
  • Financially better for many users
  • Easier transfers and brand loyalty
  • Predictable recurring revenue for Tesla
  • Access to the latest features

Negatives

  • Higher long-term cost for loyal/long-term owners
  • No true “ownership” or permanence
  • Risk of future price hikes or even deactivation
  • Perceived as of less value
  • Impact on resale and used market

Overall, there is a split among the Tesla community in terms of what they see as the “right” way to handle this. Tesla is likely to shed more details on what its plans for the subscription-only platform will be, including pricing, in the coming weeks.

Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe. 

The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive. 

As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project. 

The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.

The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.

Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.

The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.

For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.

“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.

The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.
