    Tell me once it’s on the market. Been reading about better battery technology for years, and nothing happens.

          you’re being downvoted, yet you’re absolutely right.

          our current battery technology is shit compared to what a solid state battery would be.

          of course there have been advancements but it’s still the same battery technology, just with bigger capacities.

          it’s a perfectly good analogy.

      And can dissipate heat efficiently in the same package size. The limitation to lipo/life/li-ion package density isn’t cell volume. It’s cell volume plus heat removal overhead. Making the cells smaller doesn’t actually change anything about the cooling overhead.

    So does this company actually HAVE a solid state battery or is this still all in concept?

    Because we already know how amazing and good a solid state battery would be… When we finally get them. But the problem is actually getting them.

    Unfortunately the article seems to be mostly talking about how good a solid state battery would be and not much at all on this startup actually having anything functional.

    Ah yes more “crushing” tech… High density and fast charging… Always means it’s only good for like 100 charge cycles so it’s effectively useless in reality.

    Battery news have been so fake every time. I won’t believe any more battery tech news until I see an actual device or vehicle powered by one.

    First of all, their claims are not new. They claim this for a long time already but have not shown a minimal viable product yet. During the time they spend money in research, Tesla batteries grew to 3 times the originals.

    QuantumScape have only shown minuscule batteries, they need to scale up to car battery capacity. Only a car with their battery can prove their claims. Until that happens their stories are worth nothing.

    Charging a 75kWh large car battery in 15 minutes requires a charger of at least 300.000W. Imagine a charging station for 5 cars would need a 1.5MW power station. That is impractical. Also the current flowing into the car would be enormously high, requiring huge cables. Also inside the battery pack, huge cooling systems are required.

    More practical solutions are exchanging battery packs or battery fluid exchange (flow battery). In short time 100% recharge and virtually unlimited range if packs are slowly charged at exchange hubs. .

    QuantumScape will water down their claims and eventually publish a more or less standard LiFePo battery if the investors are lucky.

      Thanks for your insightful comment.

      Regarding 300kW charging: I thought new EVs already charge with up to 180kW DC (?), so this would “only” be a doubling in performance?

    We know solid-state batteries are good, we want someone to produce stable solid-state batteries cost-effectively.

    Yes, I’m going to base my investment on large scale technology on finance.yaoo.com, or better yet benzinga.com!! Especially after their exclusive on “Analyst Inside Look: Trends And Opportunities In Ohio’s Emerging Recreational Cannabis Sector”

    But this battery CRUSHES it! That’s more than SLAMS!!!

    Toyota said they are aiming for 2027 or 2028 with their solid state tech. I’m amped for when it comes but it’s not really fair to compare potential 5-years-out tech with present day tech.

    Is there any proof ? I’ve seen a single article. Nothing if substance. QS has been saying for years it will beat Tesla. Last earnings meeting had nothing to show. Was burning cash and keeping of research. That’s wasn’t too long ago.
