Can Flow Batteries Finally Beat Lithium?
Nanoparticles may boost energy density enough for EVs
As she drives her electric vehicle to her mother's house, Monique's
battery gauge indicates that it's time to reenergize. She stops at a
charging station, taps her credit card at the pump, inserts a nozzle
into the car, and in 5 minutes exchanges 400 liters of spent nanofluid
for fresher stuff. As she waits, a tanker pulls up to refill the
station itself by exchanging tens of thousands of liters of charged
for spent fuel. Monique closes her EV's fueling port and heads onto
the highway with enough stored energy to drive 640 kilometers (400
miles).
The battery in her EV is a variation on the flow battery, a design in
which spent electrolyte is replaced rather than recharged. Flow
batteries are safe, stable, long-lasting, and easily refilled,
qualities that suit them well for balancing the grid, providing
uninterrupted power, and backing up sources of electricity.

Great news for all those forecourts! (and folk that can't get a cable to the kerbside at their home).
I spy a little fly in the ointment: they speak of "in five minutes
exchanges 400 liters of spent nanofluid for fresher stuff."
That's a bloomin' big notpetrol tank with its associated weight
and volume penalties.
