Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

UT Austin team devises new strategy for safe, low-cost, all-solid-state rechargeable Na or Li batteries suited for EVs

Green Car Congress

John Goodenough, known around the world for his pioneering work that led to the invention of the rechargeable lithium-ion battery, have devised a new strategy for a safe, low-cost, all-solid-state rechargeable sodium or lithium battery cell that has the required energy density and cycle life for a battery that powers an all-electric road vehicle.

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 Harvesting for Wearable Technology Steps Up

Cars That Think

The best-known wearable energy-harvesting tech today is, of course, solar, which pulls down electrons from sunlight or ambient light. But solar is just the opening gambit. A backpack with a giant solar panel might work technically, but not in reality. volts for about 60 hours. Leveraging watch tech for…bisons?

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. An important one, Sprenkle adds, is understanding the value of that stored energy. “A
