- The major scientific challenge for a competitive Na-ion battery technology is to develop viable anode materials. In this paper we reported on a hybrid material made out of a few phosphorene layers sandwiched between graphene layers shows a specific capacity of 2,440mAh/g at 0.05mA/g and an 83% capacity retention after 100 cycles. Using in-situ TEM and ex situ XRD, we explained the large capacity through a dual mechanism of intercalation of sodium ions along the x axis of the phosphorene layers followed by the formation of a Na3P alloy.
