One-dimensional (1D) titanate nanotubes have garnered significant attention in the field of lithium-ion batteries due to their high specific surface area, excellent electrical conductivity, and efficient ion transport properties. However, despite simplicity hydrothermal synthesis method, underlying mechanisms by which key parameters (e.g., NaOH concentration, temperature, time) influence morphology performance materials remain unclear, thereby limiting industrial application. In this study, we employed an orthogonal design approach systematically optimize process parameters. Initially, investigated effects concentration on phase products, followed a three-factor, three-level experiment. The optimal conditions were determined be 10 mol L^-1, time 36 h, temperature 150 °C, solid-to-liquid ratio 0.0375. Under these conditions, synthesized 1D exhibited average length 387 nm, area 63.114 m² g^-1, pore size 5.54 nm. material demonstrated remarkable rate (274 mAh g^-1 at 0.5C) cycling retention (83% after more than 100 cycles). By optimizing through design, study successfully fabricated high-performance nanotubes, providing reliable technological pathway for application energy storage.
