Graphitized biogas-derived carbon nanofibers as anodes for lithium-ion batteries

The electrochemical performance as potential anodes for lithium-ion batteries of graphitized biogas-derived carbon nanofibers (BCNFs) is investigated by galvanostatic cycling versus Li/Li+ at different electrical current densities. These graphitic nanomaterials have been prepared by high temperature...

These graphitic nanomaterials have been prepared by high temperature treatment of carbon nanofibers produced in the catalytic decomposition of biogas.

Therefore, this result can be associated with the nanometric particle size as well as the larger surface area of the BCNFs which, respectively, reduces the diffusion time of the lithium ions for the intercalation/de-intercalation processes, i.e. faster charge-discharge rate, and increases the contact area at the anode active material/electrolyte interface which may improve the Li+ ions access, i.e. charge transfer reaction.Financial support from the Spanish Ministry of Economy and Competitiveness (MINECO) under Projects ENE2011-28318-CO3-02 and ENE2014-52189-C2-2-R is gratefully acknowledged.
