New electrode material obtained by pyrolysis of aquatic biomass macro (red algae) soaked with glucose solution has been characterized by SEM, EDX and Raman spectroscopy. Graphitized carbon was identified by Raman spectroscopy. Galvanostatic cyclic polarization of the materials in contact with 1M LiPF6 electrolyte in EC:DMC (1:1 v/v) and Li as a counter electrode was performed. Specific capacity of the novel material was enhanced in comparison with graphitic charge capacity. The best specific capacity was achieved for the sample with a carbon cluster size La of 39 Å and was equal to 578 mAh/g with capacity fading about 9 % for C/20 –rate.
