ELECTROCHEMICAL ACTIVITY OF CARBONS MODIFIED BY d-METAL COMPLEXES WITH ETHANOLAMINES

摘要

1. Modification of carbon materials by tri-nuclear complexes of 3 d-metals with ethanolamine ligands increases the catalytic activity with regard to the electrochemical reaction of oxygen reduction. The Co-Ni complex is most active in this reaction if pyrolyzed at 600°C. 2. Modification of Graphite-type materials by the Co-Ni complex pyrolyzed at 500°C improves significantly the performance of these material in the anode of Li battery. The inner mechanism of this effect is still unclear. We suggest the formation of nanosized spinel structures which facilitate the charge transfer across SEI. 3. No positive effect of the modification was found for Carbon-type (non-graphite) materials.
