| Summary: | Various biomass materials have been developed as precursor materials to fabricate carbon-based anodes for Li-ion battery (LIB) applications due to their inherent sustainability and low cost. However, the low theoretical specific capacity of carbon materials (273 mAh g<sup>−1</sup>) restricts their further application as an anode for LIBs. Herein, silicon/reed catkin composites (Si/RC) and silicon/apricot shell-derived carbon (Si/AC) are successfully fabricated, and their performances are evaluated as anode materials for LIBs. The Si/RC anode displays a reversible capacity of 318.4 mAh g<sup>−1</sup> after 100 cycles at 200 mA g<sup>−1</sup> and remains 229.3 mAh g<sup>−1</sup> after 1000 cycles at 1 A g<sup>−1</sup>. This work discloses the feasibility and promising prospects of utilizing biomass reed catkins to prepare low-cost, porous, carbon-based materials for energy storage applications. |
