Phosphorene, monolayer or few-layer black phosphorus (BP), has recently triggered strong scientific interest for lithium/sodium ion batteries (LIBs/SIBs) applications. However, there are still challenges regarding large-scale fabrication, poor air stability. Herein, we report the high-yield synthesis of phosphorene with good crystallinity and tunable size distributions via liquid-phase exfoliation of bulk BP in formamide. Afterwards, a densely packed phosphorene-graphene composite (PG-SPS, a packing density of 0.6 g cm−3) is prepared by a simple and easily up-scalable spark plasma sintering (SPS) process. When working as anode materials of LIBs, PG-SPS exhibit much improved first-cycle Coloumbic efficiency (60.2%) compared to phosphorene (11.5%) and loosely stacked phosphorene-graphene composite (34.3%), high specific capacity (1306.7 mAh g−1) and volumetric capacity (256.4 mAh cm−3), good rate capabilities (e.g., 415.0 mAh g−1 at 10 A g−1) as well as outstanding long-term cycling life (91.9% retention after 800 cycles at 10 A g−1). Importantly, excellent air stability of PG-SPS over the 60 days observation in maintaining its high Li storage properties can be achieved. On the contrary, 95.2% of BP in PG sample was oxidized after only 10 days exposure to ambience, leading to severe degradation of electrochemical properties. [ABSTRACT FROM AUTHOR]

In article number 1601285, Qingyu Yan and co‐workers prepare a 0D–2D Ni2P nanocrystals–black phosphorus heterostructure (Ni2P@BP, the Ni2P NCs homogeneously embedded in few‐layer BP nanosheets) by a facile sonication‐assisted exfoliation and a solvothermal process, which exhibits high electrical conductivity, low thermal conductivity, excellent Li storage properties and outstanding hydrogen evolution reaction (HER) electrocatalytic activities.

In article number 1600453, Qingyu Yan and co‐workers prepare a densely packed phosphorene‐graphene composite (PG‐SPS, a packing density of 0.6 g cm−3) by a simple and easily up‐scalable spark plasma sintering (SPS) process. The composite exhibits high specific capacity and volumetric capacity, good rate capabilities, in additon to outstanding long‐term cycling life, and especially robust air stability in maintaining its high Li storage properties.
