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. The present sodium-sulfur battery operates above 300 °C.

The Jadar project would support the evolution of Rio Tinto—one of the world’s largest miners—into a chemical producer to make battery-grade lithium carbonate, a critical mineral used in large-scale batteries for electric vehicles and storing renewable energy.

Cobalt extraction creates hazardous working conditions and generates toxic waste that contaminates land, air, and water surrounding the mines. Dinca and his team plan to continue developing alternative battery materials and is exploring possible replacement of lithium with sodium or magnesium, which are cheaper and more abundant than lithium.

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). There is only so much salt you can dissolve in a glass of water. Importantly, the nanofluids are engineered to remain suspended indefinitely, unlike other suspensions—for instance, sand in water.

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). When demand is high, the water is released through turbines that generate electricity. —Charles Barnhart.

This allows storage of charge at a higher volumetric or gravimetric density, which translates to a higher stored energy density or storage capacity for a given size or weight. Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge.
