Aluminium substitution in Sb2S3nanorods enhances the stability of the microstructure and high-rate capability in the alloying regime

By constraining the charging–discharging to the alloying regime, Sb 1.9 Al 0.1 S 3 nanorods deliver superior electrochemical performance for 1000 cycles at 5C rate, unlike poor cyclability observed when cycled in both conversion and alloying regimes.
