Synthesis and Electrochemical Performance of Sn-based Composite oxides
A new route-the rheological phase-precursor reaction method was employed to prepare Sn-B-P composite oxides (TBP). The structural and composition evolution of Sn-B-P composite oxides was investigated by X-ray diffraction (XRD), the electrochemical performances of TBP as anode for Li-ion batteries were studied in the form of Li/TBP cells used the galvanostatic charging-discharging experiments and electrochemical impedance spectroscopy (EIS). The results revealed that the existence of inactive B<,2> O<,3>, P<,2>O<,5> component not only increase the interface impedance, but also change the electrochemical reaction course and controlling step. So, compared with that of SnO, the electrochemical performances of the samples dispersed B-P is hardly improved.
