Книга: Ozgul Keles,Khalil Amine and Billur Deniz Polat «Nanocolumnar Porous Cu-Sn Thin Film as Anode Material for LIB»

Производитель: "LAP Lambert Academic Publishing"

Thin film coating technologies have taken attention for LIB battery makers for two decades. These technologies have shown the opportunities to develop new electrode materials with various compositions and morphologies delivering higher sustainable reversible capacities in batteries. In this study, two nanocolumnar structured porous Cu-Sn films were produced by tuning the duration of an oblique angle deposition (OAD) technique of electron beam co-evaporation method. The structural and morphological properties of these porous Cu-Sn films are characterized by thin film X-ray diffraction, scanning electron microcopy (SEM),atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). Galvanostatic half-cell electrochemical tests of the Cu rich Cu6Sn5 thin film having homogenously distributed nanocolumns delivered a good cycleability upto 100 cycles with a high capacity retention; while the Cu6Sn5 nanostructured porous thick film with inhomogeneous morphology only showed...
