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.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. These nanodots, roughly 10 nanometers wide, were connected to the MXene’s layers by carbon materials. A paper on their work is published in the journal Small. Alhajji, E.,
