Amplification of the discharge current density of lithium-ion batteries with spinel phase Li(PtAu)0.02Mn1.98O4 nano-materials

Author: Ross, N ; Iwuoha, EI ; Ikpo, CO ; Baker, P ; Njomo, N ; Mailu, SN ; Masikini, M ; Matinise, N ; Tsegaye, A ; Mayedwa, N ; Waryo, T ; Ozoemena, KI ; Williams, A Date: May 2014 In this study the synergistic and catalytic properties of a novel nano-composite cathode material of nominal composition Li(M)(subx)Mn(sub2-x)O(sub4) (M = Pt-Au; x # 0.2) has been explored. Li(PtAu)xMn(sub2-x)O4 nanomaterial for use in ... Read more
Electrokinetic and impedimetric dynamics of FeCo-nanoparticles on glassy carbon electrode

Author: Ikpo, CO ; Njomo, N ; Ozoemena, KI ; Waryo, T ; Olowu, RA ; Masikini, M ; Baleg, AA ; Jahed, N ; Baker, PGL ; Iwuoha, EI Date: Jan 2013 The electrochemical dynamics of a film of FeCo nanoparticles were studied on a glassy carbon electrode (GCE). The film was found to be electroactive in 1 M LiClO4 containing 1:1 v/v ethylene carbonate – dimethyl carbonate electrolyte system. ... Read more
Graphenated tantalum(IV) oxide and poly(4-styrene sulphonic acid)-doped polyaniline nanocomposite as cathode material in an electrochemical capacitor

Author: Njomo, N ; Waryo, T ; Masikini, M ; Ikpo, CO ; Mailu, S ; Tovide, O ; Ross, N ; Williams, A ; Matinise, N ; Sunday, CE ; Mayedwa, N ; Baker, PGL ; Ozoemena, KI ; Iwuoha, EI Date: May 2014 Nanostructured poly(4-styrene sulphonic acid) and tantalum (IV) oxide-doped polyaniline nanocomposite were synthesised and their electro-conductive properties were determined. The oxide was synthesized using a modified sol-gel method and then ... Read more
Novel iron-cobalt derivatised lithium iron phosphate nanocomposite for lithium ion battery cathode

Author: Ikpo, CO ; Jafta, CJ ; Ozoemena, KI ; West, N ; Njomo, N ; Jahed, N ; Baker, PG ; Iwuoha, EI Date: Jan 2013 Described herein is the electrochemical study conducted on lithium ion battery cathode material consisting of composite of lithium iron phosphate (LiFePO(sub4), iron-cobalt derivatised carbon nanotubes (FeCo-CNT) and polyaniline (PA) nanomaterials ...
