摘      要：Phosphorus sulfide cage molecule based on P4S3 was investigated for the first time as anode material for the storage of alkali metal ions(Li+, Na+, K+). Such P4S3 sample was obtained in a large scale by a simple heating reaction of low-cost rep P and S. X-ray diffraction refinement analysis indicates that P4S3 sample possesses a defect rich molecule crystal structure with S/P atom ratio of 0.74. The P4S3 anode delivered a high reversible capacity of 1266 m Ah g-1 for lithium-ion batteries at 0.1 A g-1 and good cycling performance. Experimental results demonstrated that the P4S3 anode undergoes a reversible Listorage reaction of P4S3+ 11 Li++ 11 e-←→ 0.5 Li4P2S6+ 3 Li3P during cycling. It also exhibited a high capacity of 1002 and 378 mAh g-1 at 0.1 A g-1 for Na+and K+storage, respectively. These properties suggest the promising application of P4S3 anode in high energy batteries.
