Tin-Based Anode Materials for Lithium-Ion Batteries
Tin oxide has a theoretical reversible capacity of 783 mAh g −1.An irreversible reaction occurs prior to the SnLi 4.4 formation: the reduction of SnO 2 to Sn and the formation of a matrix of Li 2 O. However, Li 2 O is not decomposable which means that a large irreversible capacity of 711 mAh g −1 is associated with this reaction. It is important to remember that for a …
