Graphitized carbon material was obtained by one-step physical activation of hydrolised lignin (HL). It has been
established that the main structural units of HL (AHL) pyrolysis products at various temperatures are nanographites and/or few-layered nanographenes with zigzag and armchair edges. The resulting materials, as well as products of their chemical modification, have prospects of using them as electrode materials in energy storage and conversion devices. Fluorination of lignin and its thermally activated forms leads to higher initial voltage of lithium battery made using the obtained materials. Samples of some fluorinated AHLs can be used as electrodes in rechargeable (secondary) batteries.
