Abstract: There is described a carbon material comprising sp2 and sp3 hybridised carbon. Also described is a method of making a carbon material the method comprising: exposing a substrate to a flux of at least 1011 carbon ions per cm2 of substrate per 1 ms, a majority of the carbon ions having a kinetic energy of at least 10 eV. Further, electrodes comprising the carbon material are described. The electrodes may operate as an anode in Li ion battery characterised with improved specific capacity and operation life-time.
