A new kind of battery stores energy in what researchers are calling “rechargeable fuel”—electrodes in liquid form. The result . . . theoretically allow an electric car to travel 500 miles on a charge, five times farther than most electric vehicles can now . . .
Batteries that use liquid electrodes could also be safer than conventional ones, says Ping Liu, a program manager at the Advanced Research Projects Agency for Energy, which is funding the work. Rechargeable fuels are at an early stage, but ARPA-E has deemed them promising, announcing funding for four groups that are developing the technology. In addition to the Illinois project, it is backing projects at GE, the National Renewable Energy Laboratory, and 24M, an MIT spinoff.
