Herein, we report a silicon-porphyrin hybrid based pearl-chain-like anode material, obtained by a simple step-by-step vapor deposition method. It demonstrates that the self-assembly of porphyrin molecules onto the pearled silicon nanowire (SiNW) surface is a promising route to significantly improve lithium-ion flux through the active materials and also alleviate the volume strain of silicon during the cycling process. Consequently, a large capacity up to 4752 mAh g-1, improved rate capability, and excellent capacity recovery can be attained. Equally important, our straightforward fabrication process has the scale-up potential to enable SiNW-based battery technology.
