Re: [EVDL] Solid State Batteries differences
I haven't been able to find anyplace to order Solid State batteries in hobbyist/engineering quantities, or found datasheets yet. I've been avoiding getting excited about solid state batteries until some of that becomes available. Can anyone point me to a P/N or a datasheet for a solid state battery cell yet?

Of course, there are other > factors. Except that that's not what's doubled. It's the specific energy in Wh/KG that's doubled. Doubling SE is great, but how it effects EV range vs cost depends on battery cost per unit of weight. Also, if it's a larger battery, some of the cost vs range advantage could be wiped out by engineering and tooling costs to redesign the battery and mounting, and material costs in manufacturing. However, doubling the *energy density* in *Wh per liter* would mean that for a given SIZE of battery, the storage capacity would double. That's HUGE. It would allow nearly doubled range for any existing EV without redesign of the battery tray. Alas, that's not the case here.

Re: [EVDL] Solid State Batteries differences
Do you have any cost information ? I just did a bunch of searches but nothing turned up for me. If the current price were half that of electrolyte cells, then double the energy density would be a wash on overall cost. Of course, there are other factors. But, as with all new technology, price comes down rapidly as production scales up. I didn't know that production had started. That's exciting !
