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.

Aqua Metals has developed a process for recycling lithium-ion batteries that it says is much cleaner, more efficient and more cost-effective than current methods (see our recent in-depth interview with company execs ). At full scale, Aqua will provide 30% of the nickel and lithium carbonate needed at 6K’s PlusCAM facility.
