Tin is a promising anode material for sodium ion batteries. Theoretical [1] specific capacity = 847 mAh g-1 and volumetric capacity = 6238 mAh cm-3.
Needs review: this page is a brief stub. It would benefit from expansion covering mitigation strategies for the volume-expansion and ion-trapping challenges listed below, and how tin anode performance compares with hard carbon and other Na-ion anode materials.
Challenges:
- large volume expansion
- structural stability
- electrolyte compatibility
- large sodium ion can lead to ions being trapped
