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 ? —Sun et al.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Schematics of Li + /Na + mixed-ion battery. 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. Chen et al.

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

Green Car Congress

Schematic illustration of the designed hybrid-seawater fuel cell and a schematic diagram at the charged–discharged state. 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.
