| Abstract: | A morphology-conserved transformation yields Sn@C nanowires (UTP@CW, ～21 wt% carbon and ～77 wt% tin) with a high encapsulation density of ultrafine tin nanoparticles in porous carbon nanowires, which exhibit excellent reversible capacities and cycling performance for lithium ion batteries, especially at high current rates. |
