A New Composite Material on the Base of Carbon Nanotubes and Boron Clusters B12 as the Base for High-Performance Supercapacitor Electrodes

We explore the quantum capacitance, stability, and electronic properties of single-walled carbon nanotubes decorated with B12 icosahedral boron clusters by first-principle calculation methods implemented in SIESTA code. After optimization built supercells, formed bonds walls demonstrated metallic all cases. The network its large area branched surface is able to increase capacity electric double-layer capacity, but low each nanotube this limits application supercapacitors. found that addition both outer inner increased capacitance nanotubes. transmission function near Fermi energy showed an conductivity supercells. It was also concentration structure led a decrease heat formation positively affects stability specific charge density concentration, considered material asymmetric electrode.
