“…Basedonthis consideration,m any researchers expanded their sight to relatively stablep hosphides. As eries of phosphides, such as NiP 2 , [10] Ni 3 P-Ni, [11][12][13] Ni 2 P, [14,15] Cu 3 P, [16] CoP, [17][18][19][20] CoP 2 , [21] Ni 5 P 4 , [22,23] FeP, [24,25] Sn 4 P 3 @C, [26] Cu 3 (PO4) 2 @C, [27] and Mn 2 P 2 O 7 -C@reduced graphene oxides [28] have been successfully synthesized and applied as the anode in Li-ion batteries. Among these phosphides and phosphates, CoP with ah ight heoretical capacity of 894 mAh g À1 and relatively low charge and discharge voltage platforms (0.9 and 0.6 V, respectively) is suitable for secondary battery anodes.…”
