New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

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.

Energy storage: the key to a decarbonised future

Setec Powerr

We are transitioning from fossil fuels to renewable energy sources such as wind and solar, and the use of energy storage is becoming more widespread. Just like we put food in the refrigerator, we can store it for days or weeks without eating it immediately or discarding it. So what exactly is energy storage? Mechanical storage.

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

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.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate. For capacitors, voltage translates to electrons stored —the voltage drop across a capacitor is proportional to its total charge.) volts for about 60 hours.

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

Green Car Congress

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.
