Water-Based Battery Could Extend EV Range Beyond 240 Miles

Scientists at GE Global Research and the Lawrence Berkeley National Laboratory are developing a new kind of water-based “flow” battery for electric vehicles that could achieve single-charge driving range of 240 miles, “and go beyond it,” GE says.

‘Go With the Flow,' says GE: ‘New water-based battery could extend EV range beyond 240 miles.’

The flow battery could be 75% cheaper than those on the market today, “and multiply current EV driving range,” GE says. The project is lead by Grigorii Soloveichik, who serves as director of the GE-led and Department of Energy-funded Energy Frontier Research Center.

“The DoE wants a battery that can power a car for 240 miles,” Soloveichik says in a GE report. “We think we can exceed that goal.”

Unlike lithium ion and other high-end battery systems, the new technology will use water-based solutions of inorganic chemicals capable supplying high energy density by ferrying more than one electron at a time, GE says. Researchers call it a “flow” battery “because the discharge and recharge occurs in electrochemical cells that stand apart from the energy storing tanks, which makes them safer.”

‘A Game-Changing Technology’

“We envision a flow battery with applications for both transportation and large-scale energy storage,” Soloveichik said. “For EVs, this represents a game-changing technology.”

The research is part of the Department of Energy’s ARPA-E RANGE program that seeks to develop game-changing electrochemical energy storage technologies. RANGE stands for Robust Affordable Next Generation EV Storage.

Engineers from GE and the Berkeley Lab says they plan to develop a working prototype and “demonstrate feasibility” of the flow battery concept over the next year, GE says.
