ChemInform Abstract: Nanospheres of a New Intermetallic FeSn₅ Phase: Synthesis, Magnetic Properties and Anode Performance in Li‐Ion Batteries.

Abstract

Fe0.74Sn5 nanospheres are synthesized from a mixture of Sn nanospheres (obtained by reduction of SnCl2 with NaBH4 in tetraethylene glycol at 170 °C) and FeCl3 in tetraethylene glycol (205 °C, 2 h).

Facile synthesis of hollow Sn–Co@PMMA nanospheres as high performance anodes for lithium-ion batteries via galvanic replacement reaction and in situ polymerization

“…However, the commercial graphite anodes in current LIBs could not meet the increasing demands of social requirements due to their low specific capacity (372 mAh g −1 ). Owing to higher theoretical capacity, lower operating potential versus Li, better morphology diversity and rich resource, Sn-based intermetallic compounds have been widely investigated as the anode materials for LIBs [3][4][5][6]. Nevertheless, the large volume change during charge/discharge cycling results in the capacity fading and poor cycle life.…”

One-step synthesis of Ni3Sn2@reduced graphene oxide composite with enhanced electrochemical lithium storage properties

“…Because of the buffering effect of inert M matrix, the M-Sn alloy exhibits enhanced electrochemical cycling performance compared with pure tin anode. These inert matrixes such as copper [8][9][10], cobalt [11,12], nickel [13,14] and iron [15,16], etc. have been explored to fabricate Cu-Sn, Co-Sn, Ni-Sn and Fe-Sn alloys as anode materials for LIBs.…”

Colloidal Tin–Germanium Nanorods and Their Li-Ion Storage Properties

“…Owing to their excellent size, shape, and compositional homogeneity, colloidally synthesized inorganic nanostructures are considered as future building blocks for novel electronic and optoelectronic materials . At present, monodisperse inorganic nanocrystals (NCs) smaller than 20 nm and with size distributions not exceeding 10–20% serve as a convenient platform for studying individual size-dependent properties of NCs (luminescent quantum dots, nanomagnets, and catalysts) − and collective optical or electronic responses in NC arrays (charge transport, lasing, photoconductivity, photovoltaics). − There is also a growing recognition that complex electron and ion transport phenomena occurring in Li-ion batteries (LiBs) and in related electrochemical energy storage technologies can also be better understood and further tailored using well-defined NCs as active electrode materials. − In the last 10 years, nanostructuring has revived a tremendous interest to a large number of those alternative cathode and anode materials which, despite the ability to uptake large quantities of Li-ions, were previously discarded on the basis of poor electronic conductivity, slow reaction kinetics, or large volumetric changes. Nonexhaustive list of these substances includes group IV elements (Si, Ge, Sn), their alloys and heterostructures, as well as metal oxides and fluorides. − …”
