Exploring 3D printing in the field of sodium-ion batteries is a great challenge since conventionally inks cause unavoidably compact filaments or frameworks, which significantly hamper infiltration electrolyte and diffusion big-size sodium ions (1.02 Å), resulting low reversible capacities. Here, new hierarchical porous frameworks are printed for storage by employing well-designed GO-contained inks. The resultant possess continuous filaments, multihole gridding. Such distinct properties render these able to facilitate fast transportation both ion electron. As result, 3D-printed reveal high specific capacity as well rate performance periodic steadiness up 900 cycles storage.
