Solid state batteries?

[Superb_Raccoon]

So I came across a company selling a power station based on solid state batteries:

Yoshino B660 SST Solid-State Portable Power Station - Yoshino Power

Unleash the power of portability with Yoshino's B660 SST. Delivering 660W in a compact design, it powers your electronics and small appliances anywhere. Ideal for backyard movie nights or camping trips. Experience the safer, lighter, and more reliable solid-state power with Yoshino.

That is 602Wh per their claim. The packs are 16.2v, so 3 would be a 48v battery, and 4 would be 72v. Which means 12.5Ahr for 699... of course a lot of extra crap their we don't need, like a big case, inverter, charger, etc.

Still, the unit is just 17lbs, so if half of that is crap... 8.5lbs in batteries. Maybe less? They claim 25% lighter than a standard battery. You can see the rought size and shape of the battery here:



Of course, it might be tricky to find a BMS for it, especially since SSB's can charge and draw power way above what a Li-Ion can do.

Tempted to see if they sell "replacement batteries" for the units...

Maybe it's the same thing as the bare batteries in this thread?

Is the semi solid state claims from Chinese batteries true?

I'm doing some research for a new battery build where I aim to increase the energy density compared to my old builds (30Q & VTC6). The obvious route (at least for me) is to look into cells as Samsung 35E to push the number towards 240 Wh/kg @ 3A. I can't find any 21700 cells that would go...

Such as:

Less unneeded junk to remove with those, like the inverter to household current.

Kinda.

Two of those in series (7s for the discharge rate) would be 24Ahr and 968Whrs, and 4.6Kg.
Compared to a 20Ahr 52v battery with 1040Whrs and 6Kg.

At almost double the cost for 1.4Kg, or about 3lbs savings.. not sure it is worth it.

Now the 30Ahr model, at 6Kg or ~13lbs assuming 2 in series, that is pretty energy dense, basically 50% more power for the same weight as the 20Ahr Li-ion battery... and no fires.

Edit: I just saw they don't properly update the voltage, and the 12S is actually 44v. So that is really 6.5 lbs for 1320Whrs.

All in an approximately 3.2x4.5x7.8 inch package.

Tempting...
