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.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

As described in an open access paper in the journal NPG Asia Materials , the system is an intermediate between a battery and a fuel cell, and is accordingly referred to as a hybrid fuel cell. Sodium can serve as an alternative to lithium in rechargeable batteries as the reversible storage mechanisms for sodium ions are very similar (e.g.,

Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery

Green Car Congress

Batteries based on this system allow the use of various anode materials, such as lithium and sodium, without the requirement to develop new cathode intercalation materials. These materials have been found to allow topotactic [transformation within a crystal lattice] and reversible extraction/insertion of oxygen atoms. —Hibino et al.

Chinese steel group Tsingshan investing $375M to build lithium plant in Argentina with Eramet

Green Car Congress

It is a key milestone in the deployment of our strategic roadmap which aims at positioning Eramet as a reference player in metals for the energy transition. Purification of the lithium, then reaction with sodium carbonate to convert it to lithium carbonate. Fresh water is then used to release the stored lithium.
