We reported an efficient and cost-effective strategy for self-assembly of ZnO nanoparticles attached to 3D pleated Zn-3(PO4)(2)/C from cola (ZnO/Zn-3(PO4)(2)/C). Wherein, 3D pleated Zn-3(PO4)(2)/C conductive buffer and ZnO nanoparticles were generated together under one-step hydrothermal process without secondary recombination. ZnO/Zn-3(PO4)(2)/C as anode shows the high reversible capacity of 946 mAh g(-1) after 150 cycles at 0.2 A g(-1) and the outstanding long-cycling stability of 641 mAh g(-1) after 600 cycles at 1 A g(-1). The significantly enhanced lithium storage can be ascribed to that novel pleated Zn-3(PO4)(2)/C conductive buffer accommodates the volume variation, ensures the abundant active sites and disperses ZnO nanoparticles to a certain extent during the repeated cycles. These make ZnO/Zn-3(PO4)(2)/C a potential anode for lithium ion batteries (LIBs) and provide new ideas to develop materials for other energy storage devices.
