Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

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.

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). While high-energy Li-ion batteries (LIBs) are expected to contribute in part to the solution, the high cost and low stability prohibit wide application in this area, the researchers observe. In a prior study, they developed a new Li-ion battery electrode—Li 1.1

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5 nanometers in size.
