Scientists discover material that can be made like a plastic but conducts like metal      (via sciencedaily.com) 

Scientists have discovered a way to create a material that can be made like a plastic, but conducts electricity more like a metal. The research shows how to make a kind of material in which the molecular fragments are jumbled and disordered, but can still conduct electricity extremely well. This goes against all of the rules we know about for conductivity.

Limits of lithium extraction from thermal water      (via sciencedaily.com) 

Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility -- the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers has now summarized the state of the art, analyzed raw materials markets, and assessed technologies.
