Ultrasound-assisted fabrication of a new nanocomposite electrode of samaria and borazon for high performance supercapacitors.

The fabrication of hetero structured materials with supercapacitor applications for industrial use remains a key challenge. This work reports a new supercapacitor material with high capacitance, comprising samaria and borazon (OSm/BN) synthesized ultrasonically (40 ± 3 kHz, 200 W). The successful synthesis, probable interfaces between OSm and BN and thermal stability of the nanocomposite were studied by UV-Vis.
