Delamination of black phosphorus (BP) into monolayer or few-layer, dubbed phosphorene, and manipulation of its newly discovered properties that are unattainable by its bulk structure have been a recent scientific breakthrough. As an elemental analogue of graphene, researchers intended to exploit its structural similarity to substitute graphene as anode for lithium ion batteries (LIBs) as one of the dominant power sources for portable electronic devices. In addition, theoretical studies have revealed that Li diffusion along zigzag directions in phosphorene is hundreds times faster than that in MoS<sub>2</sub> or graphene.<br/>We will present our recent activities on synthesis of few layered black phosphorus nanosheets through diferent methods and study their Li/Na storage properties. Especially, we try to improve their chemical stability by forming composite structures with the aid of spark plasma sintering (SPS) process. It shows that excellent air stability of SPS-processed black phosphorus can be achieved over the 60 days observation in maintaining its high Li storage properties.
