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 ... -
Aligned carbon nanostructures based 3D electrodes for energy storage
Lou, Fengliu; Chen, De (Journal article; Peer reviewed, 2015)Electrochemical energy storage systems with high specific energy and power as well as long cyclic stability attract increasing attention in new energy technologies. The principles for rational design of electrodes are ... -
Aligned carbon nanotubes@ manganese oxide coaxial arrays for lithium ion batteries
Lou, Fengliu (Doktoravhandlinger ved NTNU, 1503-8181; 2013:257, Doctoral thesis, 2013)Lithium ion batteries (LIB) have attracted widespread interests due to their higher specific energy compared with nickel–cadmium batteries and lead–acid batteries. However, their specific power remains too low to power ... -
