• A novel GO-directed templating approach constructs a hierarchical nanoflower superstructure from ZIF-derived carbon, featuring radially aligned meso/macroporous nanosheets.
• The optimized ZIF-9@GO-6 anode delivers a high specific capacity of 521.8 mAh·g−1 at 0.05 A·g−1 with an excellent initial Coulombic efficiency of 89.2%.
• Exceptional cycling stability is demonstrated, retaining 298.2 mAh·g−1 after 500 cycles, outperforming conventional ZIF-derived carbons.
• This strategy resolves inherent trade-offs between porosity, conductivity, and structural stability, enabling scalable, high-performance sodium-ion batteries.
