Herein, we report on the synthesis and Li-ion storage properties of the 0D-2D nanohybrid consisted of bimetal phosphorus trisulfides nanoneedles (Co0.5Ni0.5PS3) and graphene nanosheets (denoted as Co0.5Ni0.5PS3@G). By choosing the Co0.5Ni0.5(OH)(2) nanoneedles as precursor, the Co0.5Ni0.5PS3 derived by a simple solid-state transformation (SST) process was successfully attached onto the graphene surface. The as-prepared nanohybrids showed a superior cycling stability and rate performance for Li-ion storage. After cycling at a current density of 0.5 A g(-1) for 500 cycles, the capacity are 456 mA h g(-1). Particularly, the capacity can reach 302 mAh g(-1) at a current density of 10 A g(-1), which is 66.2% of the capacity at 0.5 A g(-1). Even cycling at a current density of 50 A g(-1), the nanocomposite can still kept a capacity of 153 mA h g(-1) with a capacity retention of 33.6%.
