High-performance supercapacitors based on S-doped polyaniline nanotubes decorated with Ni(OH)2 nanosponge and onion-like carbons derived from used car tyres

Author: Bhaumik, M ; Raju, Kumar ; Arunachellan, Iviwe C ; Ludwig, T ; Mathe, Mahlanyane K ; Maity, Arjun ; Mathur, S Date: May 2020 High performance supercapacitors are designed based on hierarchical Ni(OH)2 nanosponges anchored on sulfur-enriched polyaniline (PANI) nanotubes and waste tyre-derived onion-like carbons (OLC) as counter electrode materials. The rational ... Read more
A high-rate aqueous symmetric pseudocapacitor based on highly graphitized onion-like carbon/birnessite-type manganese oxide nanohybrids

Author: Makgopa, K ; Ejikeme, PM ; Jafta, CJ ; Raju, Kumar ; Zeiger, M ; Presser, V ; Ozoemena, KI Date: Jan 2015 We present a study on the pseudocapacitive properties of birnessite-type MnO(sub2) grafted on highly graphitized onion-like carbon (OLC/MnO(sub2)). In a three-electrode setup, we evaluated two different substrates, namely a platinum disc and ... Read more
