The Chinese EV manufacturer, Nio has announced that their new ES6 SUV will have semi-solid-state batteries that offer long range with a higher energy density. See the attached article which was published in my newspaper yesterday.

What exactly is a solid state battery anyways? No liquid? That's where we are at now I thought. Cap based? well then it's not really a battery then since it's not chem based.
Either way if they can get more capacity with less weight / greater longevity then more power to them and I hope its the start of something really good here.

Yeah, no liquids inside freeing the manufacturers from some physical boundaries resulting in much higher energy density (factor 2 and up).
If that article is really true, remains to be seen. Wouldn't be the first piece of Chinese propaganda which turns into thin air when closely looked at.

Current cells are sealed with a liquid electrolyte inside (the cell is actually tightly packed and is more wet than fluid so it's best not to think of it like a can of cola or whatever), Energicas use Lithium Polymer which is still technically a liquid electrolyte but the electrolyte is some kind of weird polymerised substance rather than a simple compound. Solid state batteries use a solid electrolyte (though again, less brick, more powder) which potentially can achieve greater power density, higher charge/discharge rates, and better thermal performance but not all of those are realised in current solid state products and IIRC nobody has managed to get a mass produced one out yet.
