Polyacrylonitrile and cobalt–tin compounds based composite and its electrochemical properties in lithium ion batteries

Hydrothermal synthesis and electrochemical properties of nano-sized Co–Sn alloy anodes for lithium ion batteries

“…Hydrothermal route, with respect to the relative simplicity and prominent flexibility, is recognized as a powerful technique for the preparation of a variety of nanostructured amorphous and crystalline Sn-based alloys, including Co-Sn alloys [4][5][6][7], Fe-Sn alloys [8] and Sn-Sb alloys [9,10]. These alloy materials showed better cyclic performance than the comparable ones prepared by mechanic melting method [6,9] and chemical reduction process [8].…”

Cobalt and tin oxalates and PAN mixture as a new electrode material for lithium ion batteries

“…The organic polymer may contribute to disaggregating the small metallic particles. The use of organic polymers such as polyacrylonitrile (PAN) in composite electrodes has been proposed [3,4]. The use of PAN (A[CH 2 ACH(CN)] n A) can be advantageous because of its ability to interact with metallic surfaces, electronic conductivity and easy denitrogenation that yields to carbon [5].…”

A facile carbothermal preparation of Sn–Co–C composite electrodes for Li-ion batteries using low-cost carbons

“…Most probably, Li x Sn phases are the products of the electrochemical reaction of tin metal component in the composite material. Recently, it was demonstrated that pure nanodispersed CoSn 2 does not show the typical anodic peak commonly ascribed to the formation of Li x Sn phases [40]. On further charge, a large number of reflections could be indexed to Sn, CoSn, CoSn 2 , and Li 13 Sn 5 (Fig.…”
