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.

Scheme of the new full sodium-ion battery, which combines an intercalation cathode and a conversion anode. The reported performance of the new Na-ion battery suggests that the sodium-ion system is a potentially promising power source for promoting the substantial use of low-cost energy storage systems in the near future, the team concluded.

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. —Yi Cui.
