摘　　要：With the in-depth research of sodium-ion batteries(SIBs),the development of novel sodium-ion anode material has become a top priority.In this work,tube cluster-shaped SbPS_(4)was synthesized by a high-temperature solid phase reaction.Then the typical short tubular ternary thiophosphate SbPS_(4)compounded with graphene oxide(SbPS_(4)/GO)was successfully synthesized after ultrasonication and freeze-drying.SbPS_(4)shows a high theoretical specific capacity(1335 mAh/g)according to the conversion-alloying dual mechanisms.The unique short tube inserted in the spongy graphene structure of SbPS_(4)/GO results in boosting the Na ions transport and alleviating the huge volume change in the charging and discharging processes,improving the sodium storage performance.Consequently,the tubular SbPS_(4)compounded with 10%GO provides an outstanding capacity of 359.58 mAh/g at 500 mA/g.The result indicates that SbPS_(4)/GO anode has a promising application potential for SIBs.
