摘要: Abstract Aqueous Na-ion capacitor and battery are of great significance for both wearable electronics stationary energy storage due to the inherent safety low cost. However, conventional NaTi2(PO4)3 materials with irregular morphology large size prepared by solid-state reaction still hinder application these systems. Herein, a newly structured porous single-crystal uniform sizes was fabricated via well-designed novel liquid transformation ultrathin TiO2 nanosheets, followed coating conductive carbon sheath. To best our knowledge, this is first report structure materials. Examined in three-electrode cell, electrode demonstrates an outstanding rate capability 80–102 mA h g−1 at varied current densities 0.5–3 A g−1 synergistic effect between nanostructure stability originated from structure. The high-quality also assembled N-doped fabricate aqueous robust flexibility. This work paves way designing advanced Na super ion conductor (NASICON) based
