developments on battery technology. seems like obvious application EVERYWHERE... especially ERS system in F1.
Atom-thin water layers may lead to faster electric cars

Aaand it's made of tungsten. You'd need the extra power to compensate the extra weight.
This is kinda like the hullaballoo about sodium batteries. Sure, more efficient than Li-ion, but heavier. Lithium is still king.

That article is an add, and really misleading IMO. The following line makes not much sense at all.
but what about the speed of delivering that energy?
Anyone familiar with how electricity works, should raise an eyebrow or two.

I could see something like this being used as a surge battery to absorb braking energy. You aren't as worried about total capacity as you are about charging rate. If you've got one small, high C battery that can store enough energy to get the vehicle up to highway speed, then the rest of the batteries just need to be able to supply the energy to overcome drag and rolling resistance. Those batteries can be optimized for energy density (range).

Yes, that is a valid approach. We had two battery technologies fitted to our 1993 solar car, to exploit the advanatages of each,and we also had supercaps for regen braking tho that didn't get used on the race
