    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.
