Anisotropic black phosphorene nanotube anodes afford ultrafast kinetic rate or extra capacities for Li-ion batteries
文献摘要：
As an important anode material for fast-charging Li-ion batteries(LIBs),black phosphorus(BP)has attracted extensive attention.Black phosphorene nanotubes(BPNTs)can be theoretically produced by rolling up the black phosphorene nanosheet along armchair(a-BPNTs)and zigzag(z-BPNTs)directions.The effects of curvature,chirality,Li-storage concentrations and strain stress on the Li-storage perfor-mance such as Li diffusion barriers and mechanical stabilities of BPNTs are mainly investigated by first principles calculations.The theoretical calculations predict that the a-BPNTs and z-BPNTs have good max-imum Li-storage capacities,and the z-BPNTs exhibit better flexibility than a-BPNTs.The mechanical sta-bilities and Li-migration are all related to the curvature of BPNTs.Additionally,both a-BPNTs and z-BPNTs exhibit fast Li-ion conductivity along the c-axis direction.Moreover,the average Poisson's ratio of a-BPNTs(0.68)is larger than that of z-BPNTs(0.17),indicating that the strain stress is more difficult to apply on a-BPNTs than z-BPNTs.Our calculations predict that the a-BPNTs can afford ultrafast kinetic rate for fast-charging and high-power LIBs,while the z-BPNTs can provide extra capacity for high-energy LIBs.
