New organic cathode for high performance solid-state sodium-ion battery

Green Car Congress

Solid-state sodium-ion batteries are safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Yao also is a principal investigator at the Texas Center for Superconductivity at UH. —Yan Yao.

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

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. Example of a lithium-water rechargeable battery.

ARPA-E awards $38M to 12 projects leading used nuclear fuel recycling initiative

Green Car Congress

Upon discharge from a nuclear reactor, the UNF is initially stored in steel-lined concrete pools surrounded by water. Most of the nation’s used fuel is stored at more than 70 reactor sites across the country. It is later removed from the pools and placed into dry storage casks with protective shielding. Award amount: $1,580,774).

U-M leads new DOE-funded research center for ceramic ion conductors; MUSIC

Green Car Congress

The University of Michigan (U-M) and eight partner institutions will explore the use of ceramic ion conductors as replacements for the traditional liquid or polymer electrolytes in common lithium-ion batteries for electric vehicles and in flow cells for storing renewable energy in the grid.

Researchers devise electrode architectures to prevent dendrite formation in solid-state batteries

Green Car Congress

But the promise is worth pursuing, says MIT Professor Yet-Ming Chiang, because the amount of energy that can be stored in experimental versions of such cells is already nearly double that of conventional lithium-ion batteries. The team solved the dendrite problem by adopting a compromise between solid and liquid states.
