3D aligned-carbon-nanotubes@Li2FeSiO4 arrays as high rate capability cathodes for Li-ion batteries
Zhou, Haitao; Lou, Fengliu; Vullum, Per Erik; Einarsrud, Mari-Ann; Chen, De; Vullum-Bruer, Fride (Journal article; Peer reviewed, 2013-09-27)3D aligned-carbon-nanotubes (ACNTs)@Li2FeSiO4 nanocomposite arrays on Al foil were developed as cathode materials for Li-ion batteries. The ACNTs were grown directly on an Al foil by a chemical vapor deposition method to ... -
Boosted Supercapacitive Energy with High Rate Capability of aCarbon Framework with Hierarchical Pore Structure in an Ionic Liquid
Wang, Xuehang; Zhou, Haitao; Lou, Fengliu; Li, Yahao; Buan, Marthe Emelie Melandsø; Duan, Xuezhi; Walmsley, John Charles; Sheridan, Edel; Chen, De (Journal article; Peer reviewed, 2016)The specific energy of a supercapacitor (SC) with an ionic liquid (IL)-based electrolyte is larger than that using an aqueous electrolyte owing to the wide operating voltage window provided by the IL. However, the wide-scale ... -
