Unlocking the potential of amorphous red phosphorus films as a long-term stable negative electrode for lithium batteries

Amorphous red phosphorus films (NS-RP) synthesized by a high energy sonication technique delivered a reversible capacity of 2137 mA h g(-1) when used as a sole active lithium battery anode. After incorporation of reduced graphene oxide in NS-RP, the hybrid delivered a reversible capacity of 706 mA h g(-1), even after 200 cycles.
