@yoatmon That part's surely a pipe-dream. Using a sulfur cathode is a whole different beast altogether. Which is also unsolved, and might remain as such, since their main problem is that sulfur doesn't conduct electricity. Kind of silly of them to mix it in with this about solid electrolytes.
It's nice to see that 24M matured into "producing" semi-solid vaporware instead of flow vaporware.
@HarveyD | A large number of fast chargers are not viable, because they'd put an obscene load on the electric grid. If they're not constrained naturally they will have to be restrained by regulation. It's far easier to install home/parking-space outlets for load balanced charging as EV's share increases. (And approximately no-one cares about rex EVs.)
If it's really that cheap this might be something very good. The coulombic efficiency also looks really good (), judging by the linked paper. Stable above 99% after 700 cycles! (At low rates anyway)
After using Li metal anodes and sulfur cathodes, the energy density is a measly 300Wh/kg? On the market Li-ion cells are near this (if they haven reached it already) with better efficiency and provenly better cycle life.
It may be cheaper because of the lack of lasers, but certainly slower than laser sintering. It has an extra sintering step, but also I expect that the printing process is slower, because nothing's really as fast as a laser beam scanning the whole surface. Certainly not printing binder with a moving head.
"for a total of 100% clean energy. " BS. It does not include heating and not even cars, since they didn't decide to ban them off the roads. "Turkey and other similar places should follow Diablo Canyon exemple and switch to other (more economical) zero emission energy production means. " There's no more economical zero emission electricity production. Nuclear is the best.
@Engineer-Poet Thanks. (How do you follow comments? I didn't find any feature to get new comment notifications)
What's the point in having tin in the anode? Why not just use plain lithium?
I surprise they don't mention bio-fuels, it's easier to sell these days. Many of the simpler alkanes and alcohols can be used in a SOFC.
Why isn't anyone working on bio-producing butane? It's pretty much the ideal fuel based on it's energy density (both gravimetric and volumetric) and pressure requirements, which is pretty low.
This is utterly pointless. With solid electrolytes you can just dump the graphite and not replace it with silicon.
This sounds potentially revolutionary for cars made of composite materials.
It's not really a fuel if you need to produce it...
Curious, seeing neither of these materials turn into smoke and spread in the atmosphere. They remain concentrated in the cells at the end of their life just as they were at the start...
@Paroway I agree, though you can't drive without using the break pedal. It's more of an idiotic marketing misnomer. That said I think the feature they should implement is an adjustable automatic regen + brake by wire. They could call it regen drag or something which at it's fullest would brake as much the full power of the engine permits. The brake pedal should also use regen. And should automatically add friction braking when regen is maxed out.
This is just stupid. Induction motors cost less and have no permanent magnets. They have copper which is both light and rather common. The Tesla's have induction motors... Plus there are better concepts than the Tesla motor. There's the Evans electric motor:
