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

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. To maximize the benefit of the open structure, the researchers needed to use ions that fit; hydrated potassium ions proved to be a much better fit compared with other hydrated ions such as sodium and lithium.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. When demand is high, the water is released through turbines that generate electricity.

Rio Tinto commits $2.4B for Jadar lithium project; planning 58,000 tons/year lithium carbonate by 2029

Green Car Congress

In addition, Jadar will produce borates, which are used in solar panels and wind turbines. For example, to date the company has finalized 12 environmental studies and more than 23,000 biological, physical and chemical analyses of air and water. Based on this annual production of lithium carbonate, Rio Tinto aims to produce 2.3

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. At the depot, the spent fuel could be recharged with electricity from any source—solar, wind, hydroelectric, nuclear, or fossil fuels.
