Can "Cambridge Crude" Sludge Revolutionize EV Battery Charging?

Very interesting technology. I might have named it Cambridge Crud however.

 

nice to see people thinking out of the box.

 

wonder what the energy density they achieved..

Li-Ion is 0.90-2.23 MJ/L and Gasoline is 35 MJ/L. Liquid natural gas is 25 MJ/L. E85 is 31 MJ/L

with ~35% ICE efficiency you figure it has to be 15-25MJ/L range to be comparable

 

cool tech with future potential.

This allows the anode and cathode to be scaled for the power needed in the battery, but the energy is in solution and can be stored in a tank. You can charge the semi-solid energy carrier on-board or off board. This seems like it has huge potential for cars and electrical buffering on the grid. It sounds like it will be a while before it is commercialized.

 

yeah it has the potential to solve current EV shortcomings: long charge time and range. Given that pumping in/out would take minutes/not hours and 5-20 time density would give 350-1400mi range in current packaging.
