• most cases. The most common top-down approach for the synthesis of graphene is the reduction of GO and of graphite fluoride by thermal or chemical methods. The reduction of GO is a low cost, facile technique and yields bulk quantities of GSs. GO was first reported 150 years ago [43]. It is now being

However, for applications that need high energy densities, current insertion-based lithium-ion batteries do not match the targets

• –FeF2 nanocomposites. The electrochemical properties of these nanocomposites likely depend on the amount and type of carbon present in the nanocomposites. In our previous studies we used only graphite fluoride with a fluorine to carbon ratio of 1.1. This resulted from the reaction with Fe(CO)5 in 20 wt

• precursor was performed in a sealed tungsten carbide vial under inert conditions. The CFx powder was ball-milled for 2 h, with a ball to powder ratio of 24:1 and milling speeds of 200, 300, and 400 rpm. To adjust the active material to carbon ratio in the products, different graphite fluoride samples were
