On the high cycling stability of NbSnSb in Li-ion batteries at high temperature

Abstract : Inspired by the high performance obtained previously with TiSnSb, NbSnSb was investigated as negative electrode in Li-ion batterie. After its synthesis by ball milling and full characterization by XRD and Mössbauer spectroscopy, electrochemical tests at various current rates and temperatures were realized. The electrochemical performance at 25 and 60 °C turned out to be very promising, being better than those previously obtained with the parent electrode material TiSnSb with a specific capacity higher than 450 mAh/g maintained during more than 400 cycles at 60 °C. Preliminary tests in full cells confirmed that this anode material could be considered as a potential material for future Li-ion batteries.
