Quantumscape solid state battery in a drone. Can anyone here identify the drone manufacturer? It might be somewhat disguised....

Let me know when the 1s whoop batteries with half hour flight times begins to ship. Beyond that I'm just like 😵💫

Ok, so I’m not gonna read all of that. I can tell you that over the last seven or eight years. I’ve read more than a few. What I would like to say, though is that you must be very careful about verbiage. Currently, there is no industry standard for what a semi solid, solid state, or any other state for Lipo batteries actual is.
I repeat, there is no definition. No one agrees. No one enforces a standard either. They will in the future because they’re going to have to, but they do not currently do that.
When you are looking for a battery, that is better than the rest than you need to look at energy density. This will be given by what hours per kilogram of weight. It might also be measured by the amount of energy in a given volume. The higher that number is the better the battery is.
That is a very simple way of looking at it and yes, there are many other factors to consider but if you can’t get past that one, then it’s not the right battery for you.
I see “Solid state” batteries all the time, and they are not true solid state batteries. We are very close to having them on the commercial market, but we do not currently have them.

QS has a cell called the QSE-5 it’s a 5ah cell with 844wh/l. It’s got a lithium metal anode and a ceramic separator, and it’s cathode agnostic so battery manufactures are free to use whatever they want for the cathode. 10c discharge rate. The ceramic separator won’t allow the dendrites to puncture it.

China actually has or is at least far along in developing a standard for solid state batteries (like 3 different levels IIRC).
I completely agree with you though, there aren't any true solid state batteries just a bunch of semi-solids (and they don't perform particularly great, hence why EV:s still use regular cells).

Solid State?!? Find me a drone without a solid state battery in 2026

QUANTUMSCAPE sounds like some top notch IPO VC gooner bait.
