Abstract
The paper studies carbon nanotubes (CNTs) synthesized by chemical vapor deposition (CVD) method on Fe-0.7Co/2.1Al2O3, Fe-Co/2.1Al2O3, and Co-Mo/Al2O3-MgO catalysts for supercapacitor electrodes with LiPF6-based electrolyte. It was found that the specific capacitance of 150–200 F/g for electrodes made of a mixture of carbon materials and graphite depends significantly on the conditions of creating intergranular contacts between graphite particles and CNTs that form a system of vacancies for ion introduction, in which reversible intercalation of PF6--anions occurs with minimal difficulties.
