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 6.9 100 to 150 mA h g ? 100 to 150 mA h g ?1

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. During charging (or discharging), the storage (or release) of Li + takes place at anode, and the release (or storage) of Na + occurs at cathode. Second, this electrochemical method is green and energy efficient.
