Porous α-Fe 2 O 3 nanorods supported on carbon nanotubes-graphene foam as superior anode for lithium ion batteries

Construction of Co3O4 nanotubes as high-performance anode material for lithium ion batteries

“…Third, small particle size with increased surface-to-bulk ratio possess more sites for ions to enter and allow facile ion diffusion at high current density. Additionally, the nanotube structure possesses favorably morphological stability, which helps to alleviate the structure damage caused by volume expansion during the cycling process [35][36][37]. The basic morphology of the Co 3 O 4 nanotube is better preserved than the nanowire counterpart after 60 cycles (Fig.…”

Construction of carbon nanoflakes shell on CuO nanowires core as enhanced core/shell arrays anode of lithium ion batteries

“…comes from the formation of solid electrolyte interface (SEI) film and possibly interfacial Li ion storage during the first discharge process, which happens in all 3d transition mental oxides, including NiO [27], Co3O4 [28], Fe3O4 [29], SnO2 [30], and Fe2O3 [21]. Meanwhile, recently, Hu and co-workers found that the additional capacity might come from reversible SEI formation, and the formation of LiOH and its subsequent reversible conversion to Li2O…”

“…Particularly, one-dimensional (1D) nanostructures such as nanowires are demonstrated to manifest high capacity and enhance cycling stability due to their fast transfer of electron/ion and more stable structure during cycling [18][19][20]. The other promising strategy is to integrate CuO active materials into conductive matrixes (such as carbon, metal and conducting polymers) to construct smart hybrid architectures [1,9,11,13,16], in which structural features and electro-activities of each component are fully manifested [21]. Impressively, it has been proven that the introduction of carbon-based matrix or carbon coating on the metal oxides could significantly enhance electrochemical performance for LIBs, especially at high-rate capability.…”

Facile synthesis of α-Fe2O3 micro-ellipsoids by surfactant-free hydrothermal method for sub-ppm level H2S detection

“…Hematite (α-Fe 2 O 3 ) is one of the n-type metal oxide semiconductor materials widely utilized in the fields of catalysts, waste water treatment, pigment, magnetic materials, photo-catalyst, and electrode materials in lithium ion batteries [1][2][3][4][5][6][7]. Specially, α-Fe 2 O 3 is believed to be a promising sensing material due to its nontoxicity, stability and low cost.…”
