Abstract

Abstract: A unique 3D mesoporous interconnected Ni12 P5 /CNTs hybrid was constructed by a facile one‐step hydrothermal method and investigated as anode toward lithium‐ion batteries. The results show that Ni12 P5 nanoparticles are well hinged by the flexible CNTs, forming a hierarchically integrated structure. The system delivers an initial discharge capacity of 1108 mAh g −1 and a high reversible discharge capacity of 676 mAh g −1 after 120 cycles at 200 mA g −1 . Furthermore, the hybrid also achieved long‐term cycling stability and good rate capability, such as 584 mAh g −1 at a current density of 400 mA g −1 after 240 cycles and 245 mAh g −1 at a rate current density of 3200 mA g −1 . The enhanced electrochemical performance could be attributed to the synergistic effect of increased specific surface area, mesoporous structures, and 3D interconnected conductive network Abstract : Easy, yet effective : A facile and cost‐effective one‐step strategy was introduced to fabricate a 3D mesoporous Ni12 P5 /carbon nanotubes (Ni12 P5 /CNTs) hybrid by using natural abundant and non‐toxic red phosphorous (RP) at low‐temperature of 160 °C. The electrochemical results confirm that this unique 3D architecture has improved electrochemical performance.
