Scenario 2050: Lithium and Cobalt might not suffice
Lithium and cobalt are fundamental components of present lithium-ion batteries. Analysis by researchers at the Helmholtz Institute Ulm (HIU) of the Karlsruhe Institute of Technology (KIT) shows that the availability of both elements could become seriously critical. Cobalt-free battery technologies, including post-lithium technologies based on non-critical elements such as sodium, but also magnesium, zinc, calcium and aluminium, represent possibilities to avoid this criticality in the long term. These results are presented in Nature Reviews Materials. (2018-03-14)
