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
Fluorinated Mn3O4 nanospheres for lithium-ion batteries: Low-cost synthesis with enhanced capacity, cyclability and charge-transport

Author: Palaniyandy, Nithyadharseni ; Nkosi, Funeka P ; Raju, Kumar ; Ozoemena, KI Date: Apr 2018 A facile synthesis of fluorinated Mn3O4 nano-spheres (F-Mn3O4) from low-cost electrolytic manganese dioxide (EMD) at different temperatures and times has been reported. While the as-prepared materials are micron-sized (>200 nm) and the ... Read more
Transition metal alloy-modulated lithium manganese oxide nanosystem for energy storage in lithium-ion battery cathodes

Author: West, N ; Ozoemena, KI ; Ikpo, CO ; Baker, PGL ; Iwuoha, EI Date: Jul 2013 This paper explores the synergistic and catalytic properties of a newly developed lithium ion battery (LIB) composite cathode of LiMn(sub2)O(Sub4) modified with bimetallic (Au–Fe) nanoparticle. Spinel phase LiMn(sub)2O(sub4) was doped with ... Read more
