Na-ion versus Li-ion Batteries: Complementarity Rather than Competitiveness

Jean-Marie Tarascon (1953) is a professor at Colle` ge de France, ``Solid-StateChemistry and Energy'' chair. His early career was spent in the United States, where he developed the plastic Li-ion technology. Back in France in 1995, he created the Eu- ropean network of excellence ALISTOREERI (2001) and the French network on electrochemical energy storage (RS2E) (2012). His present research is devoted to Li(Na)-ion batteries and other chemistries with emphasis on the development of new eco-efficient synthesis processes, novel reactivity concepts, and passive sensing approaches. He is the author of more than 650 scientific papers and retains around 100 patents.
