Can flow batteries finally beat lithium?

From the article:

This battery, though, uses a completely new kind of fluid, called a nanoelectrofuel. Compared to a traditional flow battery of comparable size, it can store 15 to 25 as much energy, allowing for a battery system small enough for use in an electric vehicle and energy-dense enough to provide the range and the speedy refill of a gasoline-powered vehicle. It’s the hoped-for civilian spin-off of a project that the Strategic Technology Office of the U.S. Defense Advanced Research Projects Agency (DARPA) is pursuing as part of a drive to ease the military’s deployment of all-electric supply vehicles by 2030 and of EV tactical vehicles by 2050.
