Sb-Si Alloys and Multilayers for Sodium Ion Battery Anodes

This work describes the synthesis and testing of thin film silicon anodes for use in sodium ion batteries. Antimony (Sb)-rich phases show high capacities and negligible loss of cycling stability over 200 cycles. This work suggests that the exploration of multicomponent materials could be a promising and useful route towards the discovery of new anode materials for batteries based upon sodium and other ions.
