Graphene coating improve energy density in Li-ion battery - publication in Nature Communications

A group of scientists based in Korea, Germany and Poland (CMPW PAN) have developed a lithium ion battery in which highly crystalline graphene coats silicon cathode material. Using this material leads to batteries with energy densities two times more than commonly-used lithium ion batteries. The study has been published in the online journal Nature Communications published as "Silicon carbide-free graphene growth on silicon for lithium-ion battery with high volumetric energy density".

In short

The Center belongs to category A of scientific facilities in Poland. It was established on January 1, 2007 as a result of a merger of the Center of Polymer Chemistry of PAN in Zabrze and the Institute of Carbochemistry of PAN in Gliwice – two centers of the Polish Academy of Sciences which, for many years, had been conducting systematic work on the production and properties of macromolecular polymer and carbon materials.
