This review is focused on the theoretical and practical aspects of electrochemical c a p a c i t o r sb a s e do nc a r b o nn a n o t u b e s .I np articular, recent improvements in the capacitance properties of the systems are discussed. In the first part, the charge storage mechanisms of the electrochemical capacitors are briefly described. The next part of the review is devoted to the capacitance properties of pristine single-and multi-walled carbon nanotubes. The major portion of the review is focused on the capacitance properties of modified carbon nanotubes. The electrochemical properties of nanotubes with boron, nitrogen, and other atoms incorporated into the carbon network structure as well as nanotubes modified with different functional groups are discussed. Special attention is paid to the composites of carbon nanotubes and conducting polymers, transition metal oxides, carbon nanostructures, and carbon gels. In all cases, the influences of different parameters such as porosity, structure of the electroactive layer, conductivity of the layer, nature of the heteroatoms, solvent and supporting electrolyte on the capacitance performance of hybrid materials are discussed. Finally, the capacitance properties of different systems containing carbon nanotubes are compared and summarized.

The composites of C 60 -Pd polymer and carbon nanostructures, single walled carbon nanotubes (SWCNTs), multi walled carbon nanotubes (MWCNTs), and graphene, were synthesized chemically in benzene solution containing zero-valent Pd complex, C 60 , and carbon nanostructure. Two kinds of morphologies are observed on the surface of carbon nanoparticles during polymer deposition. Initially, a thin layer of 5 nm C 60 -Pd polymeric nanoparticles is formed. Next, these particles aggregate into bigger spherical structures ca. 150 nm in diameter. The capacitance performance of synthetized materials was investigated. Specific capacitances per mass of the polymer in the composite are significantly higher in comparison to pure chemically formed polymeric material. This effect is related to the nanostructured morphology of composite resulting in the higher efficiency of charge accumulation.Since carbon nanotubes were discovered, 1 a lot of work was dedicated to the development of materials containing nanotubes and conducting polymers. 2-10 These systems possess novel properties with superior characteristics than either of the individual components. [11][12][13][14][15][16][17] Carbon nanotube films with a high surface area allow electrochemical deposition or chemical polymerization of significant amounts of conducting polymers. Composites of conducting polymers with carbon nanotubes are promising electrode materials as supercapacitors because of their good conductivity, high surface area and their good ability to store energy. [18][19][20][21][22][23][24][25] Recently, a lot of attention has been also focused on graphene -the newest carbon material, which is preferred over other conventional carbon materials due to the ease synthesis, cost effectiveness, high theoretical specific surface area, high electrical conductivity, mechanical strength and chemical stability comparable with or even better than CNTs. 26,27 Electrodes composed of graphene sheets exhibit relatively good capacitance properties. 28-30 Graphene was also successfully used for formation of composites with conjugated polymers. These materials exhibit very promising capacitance properties. 31-36 However, the electrochemical behavior of graphene strongly depends on the synthesis method and functionalization of its surface. [37][38][39] So far, most studies have been limited to p-type polymers, such as polypyrrole, polyaniline, poliothiophene, and their derivatives. [40][41][42][43][44][45][46] We developed an electrochemical procedure for the formation of two-component fullerene films based on the electroreduction carried out in a solution containing fullerene 47-52 or fullerene derivatives 53-55 and various transition metal complexes. In these polymers, fullerene moieties are covalently bonded to transition metal atoms or their complexes to form a polymeric network. These materials exhibit electrochemical activity in the negative potential range due to the good electron-accepting properties of the fullerene moieties. The electropolymerization and electrochemical ...
