Treść
New materials obtained by pyrolysis of gelatine (G) and poly(1,2-dimethylsilazane) (PSN) (weight ratio: G/PSN 70/30) at temperatures 700 and 900 °C were characterized by SEM and Raman spectroscopy. The presence of ceramics influences on the cluster size of the materials. Electrochemical tests were performed by cyclic voltammetry and galvanostatic cyclic polarization. The capacity of G/PSN was 464 and 527 mAh/g for materials pyrolysed at 700 and 900 °C. The capacity fading was 1 % after 17th cycle for G/PSN at 900 °C. This value is higher of 185 mAh/g in comparison to capacity of gelatine pyrolysed at the same conditions. Keywords : Lithium-ion batteries; SICN ceramic materials; hard carbon; anode material
