Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

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.
