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.

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials. prepared a carbon material with interconnected pores in two size ranges.

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.

Although silicon is an abundantly available element with ten times the gravimetric energy density of graphite, several performance issues continue to limit its commercial exploitation. Graphene is a single, one-atom-thick layer of the mineral graphite (an allotrope of carbon). Source: WMG. Click to enlarge.
