Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. A typical Li-air battery discharges at 2.5-2.7

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Electrofuels approaches will use organisms able to extract energy from other sources, such as solar-derived electricity or hydrogen or earth-abundant metal ions. Water will be the primary byproduct. A novel metal complex for electrolysis of water will be used to generate the hydrogen at high rates. Electrofuels. per gallon.

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 cell of a flow battery uses two chemical solutions containing ions, one acting as the anolyte (adjacent to the anode), the other as the catholyte (near the cathode).
