Improvement of Hybrid Electrode Material Synthesis for Energy Accumulators Based on Carbon Nanotubes and Porous Structures

Carbon materials are promising for use as electrodes supercapacitors and lithium–ion batteries due to a number of properties, such non-toxicity, high specific surface area, good electronic conductivity, chemical inertness, wide operating temperature range. Carbon-based electrodes, with their characteristic power cyclic stability, can be used new generation consumer electronics, biomedical devices hybrid electric vehicles. However, most carbon materials, low electrical conductivity insufficient diffusion electrolyte ions in complex micropores, have energy density limitations these pores diffusion. This work focuses on the optimization material based porous nanotubes by mechanical mixing. The purpose this is gain knowledge about effect composition its capacitance. study taken basis nanotubes. Electrodes made were an object research. Porous or nitrogen-containing (combined single-, double-, multi-layer (single-layer nanotubes, bilayer multilayer nanotubes) create material. catalytic vapor deposition synthesis parameters, flow rate methane-to-hydrogen ratio, well type system structure was investigated. Two types catalysts Mo12O28 (μ2-OH)12{Co(H2O)3}4 prepared precipitation combustion. resulting tested lithium ion intercalation. carbon/carbon 95:5% found efficient compared nitrogen-doped 10%. synthesized using catalyst obtained selected additives mixing dispersion aqueous solution followed lyophilization remove water. When optimizing ratio components, effective carbon:carbon component determined.
