High capacity, reversible alloying reactions in SnSb/C nanocomposites for Na-ion battery applications

A new SnSb/C nanocomposite based on Na alloying reactions is demonstrated as anode for Na-ion battery applications. The electrode can achieve an exceptionally high capacity (544 mA h g(-1), almost double that of intercalation carbon materials), good rate capacity and cyclability (80% capacity retent...

Zusammenfassung:A new SnSb/C nanocomposite based on Na alloying reactions is demonstrated as anode for Na-ion battery applications. The electrode can achieve an exceptionally high capacity (544 mA h g(-1), almost double that of intercalation carbon materials), good rate capacity and cyclability (80% capacity retention over 50 cycles) for Na-ion storage.
