PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. A paper on the work appears in Nature Energy.

New high performance Janus electrode for rechargeable Na-S batteries

Green Car Congress

containing both cathode and anode properties in the same body—for sodium-sulfur (Na-S) batteries by adopting a metal-organic framework (MOF) to incorporate single Yttrium atoms in a nitrogen-doped rhombododecahedron carbon host (Y SAs/NC). Researchers in China have designed a high-performance Janus electrode—i.e.,

BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.
