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.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.
