Can Flow Batteries Finally Beat Lithium?

Cars That Think

The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The scientists found the nanofluids could be used in a system with an energy-storing potential approaching that of a lithium-ion battery and with the pumpable recharging of a flow battery.
