Silicon anodes (+ possibly LMFP cathodes) in a race with solid state to be the next dominant EV battery, a race that we all win.
🔌💡Prologium has launched a new lithium ceramic battery with 100% silicon anode, that can charge up to 80% in 8.5 minutes. It has an energy density of 320-350 Wh/kg. They are partnering with FEV to being this new battery to EVs. #EVs #battchat interestingengineeri...
Test data from TÜV Rheinland shows the battery can charge from 5 percent to 60 percent in five minutes and reach 80 percent in 8.5 minutes.

These are cool! Platinum mesh anodes for the Boise State Chemistry Department in for repair.These are cool! Platinum mesh anodes for the Boise State Chemistry Department in for repair.
That seems to match what I've seen from the data from them. IMHO it always surprises me how hot they run the cells during supercharging. But I guess that's what you need to get the sort of ion mobility in the anodes for them to intercalate fast enough for those currents ;)
the relative fire risk between EVs and ICE vehicles was given in the article, and favors EVs, and saltwater flooding is a severe test, but it seems to me that electrical shorts and fires (in batteries with flammable electrolytes and Li anodes) is largely a design problem.

Using AFM-based resistivity measurements, Zoey shows how thermal curing of Si-PEO anodes induces phase segregation between the low-resistance carbon binder and the high-resistance Si active material, which benefits the electrodes' electrochemical and mechanical properties.Using AFM-based resistivity measurements, Zoey shows how thermal curing of Si-PEO anodes induces phase segregation between the low-resistance carbon binder and the high-resistance Si active material, which benefits the electrodes' electrochemical and mechanical properties.
