Isn’t this the company where some hedge fund published report on and they have a short position? Until there is no 3rd party testing and independent publications verifying their claims I am not buying anything. I know I sound skeptical but I’ve lost enough money on SPACs.
> By weight, it offers between 380-500 Wh/kg, as compared to 260 Wh/kg in packages currently used by Tesla.<p>That's pretty huge if the company's claims hold up. That's in the ballpark where doing an EV conversion on an existing ICE car becomes a lot easier because you could theoretically just replace the original gas tank with 100-200 pounds of batteries and have a good-enough range to be useful for short/medium trips. And the car might end up lighter than stock.<p>I wonder what the material inputs are? Does this battery use cobalt or nickel or anything else that's similarly expensive? Or can these things in theory be made super cheap once the manufacturing scales up?

For comparison, a Tesla Model S Plaid charges to 80% in 30 minutes, on a v3 supercharger. Reference (exactly 78% in 30 minutes): <a href="https://insideevs.com/news/544379/tesla-model-s-plaid-supercharging/" rel="nofollow">https://insideevs.com/news/544379/tesla-model-s-plaid-superc...</a>
First commercially viable lithium solid state battery? There are Mercedes buses with solid state batteries right on the road right now:

But still, seems to be further ahead in the product development cycle.
<i>"We continue to target delivery of A-sample cells to at least one customer in 2022. The A sample is planned to have dozens of layers and is intended to demonstrate the core functionality of the battery cells."</i> That's moderately encouraging. It's better than the usual "we got this new surface chemistry result, huge revolution real soon now."<p>As with too many battery articles, this is either a huge deal or total bullshit.<p>(Electrek should have a monthly column: "1, 5 and 10 years ago in battery press releases.")
Here's a direct link to the white paper: <a href="https://www.quantumscape.com/resources/blog/white-paper-a-deep-dive-into-quantumscapes-fast-charging-performance/" rel="nofollow">https://www.quantumscape.com/resources/blog/white-paper-a-de...</a>
80% charge in 15 minutes is not far off from some current commercially available EVs using conventional li-ion technology.<p>For example, the Hyundai Ioniq 5 will charge to 80% in 18 minutes on a 350 kW charger.
Sorry if this is a silly question, but what are the moving parts that make normal lithium ion batteries not solid state?<p>Phones and laptops don't make any noticeable movement sounds when they charge, but I have noticed that my Tesla will produce some random knocking sounds when supercharging. Are these the kinds of moving parts that solid state batteries would remove?
Two thoughts:<p>* First, although they are claiming every aspect of this battery is quite a bit better, the key variable missing is price.<p>* Interesting that $1 billion investment, partially by Qatar Investment Authority. It seems the oil states may be realizing things are changing. It might also incentive them to get on board with electrification.
I think one of the biggest hurdles to overcome is actually being able to make produce a product. Because as many many have said before, prototypes are easy, mad production is where the problems lie.
Yet another revolutionary new battery. Graphene batteries, liquid salt batteries, etc etc.<p>My dad has a popular mechanics do it yourself encyclopedia from the 1950s and it has several articles of new battery technologies in the works that will be available in a few months, just you wait and see.<p>For my entire life, new batteries have been just around the corner to replace lithium ion, every 12 to 18 months, one of these articles come out.<p>At this point, I will believe them when I see them on store shelves and not one second before.

A 50 kWh car battery charging to 80% in 15 minutes would be a 160 kW average load. That's going to need high voltage or a thick cable. Is that going to be practical?<p>Also I wonder what the power connection to a busy all electric refueling station/convenience store by the highway would look like if it wanted to have 16 of these. At least there would be no fumes so it could be more enclosed than a gasoline pump, and presumably no safety reason why you'd need to pay attention to the refueling.
